Tray & Shelf Setup

Tray Cross-Section

Stack from bottom up. Mesh-in-solid lets you lift out blocks to drain and refresh water.

░░░ heat mat (germ only) ░░░

Bottom water only. Pour into the solid tray — blocks wick up through the mesh. Lift the mesh insert to check water level, drain, and refresh. Never pour water on top of blocks.

Water level: Keep ~¼" in the solid tray. Blocks should feel damp, not soggy. If the solid tray is dry, add water. If blocks are sitting in standing water, lift mesh and pour some out.

Shelf Layout

5 shelves give you room to spread out. Each lit shelf gets its own light 2-4" above. The heat mat stays on the germination shelf.

Shelves 3-5 — Growing (2" blocks)

Potted-up seedlings live here. After selecting the best minis and nesting them into 2" blocks, move them to these shelves. Light 2-4" above, fan on, cover open. Plenty of room to spread out.

Shelf 2 — Sprouted Minis

Mini blocks move here once sprouted. Light 2-4" above leaf tips. No heat mat. Fan on low. Seedlings grow here until first true leaves, then the best get potted up to 2" blocks and promoted to Shelves 3-5.

Shelf 1 — Germination Station

Fresh mini blocks go here. Heat mat ON. Light ON (even before sprouts emerge). Rack cover closed around this shelf for humidity. Check daily — move sprouted trays up to Shelf 2.

Soil Block Count

Two-stage approach: Start 1 seed per mini block (~¾"), grow to first true leaves, then select the strongest and pot up into 2" blocks. More seedlings, better selection, less seed waste.

Mini block capacity: A 1020 tray fits 150+ mini blocks easily — each wave fits in a single tray. Press minis, germinate, grow to first true leaves on Shelf 2, then pot up the best into 2" blocks and move to Shelves 3-5. Compost the runts or give them to neighbors.

Wave-by-Wave Guide

Wave 1 — Brassicas + Greens Mar 14-16

setup — 20 min

Press 46 mini blocks into Tray A (mesh in solid). Group by crop and label tray edges with tape — you won't remember which is which in a week. 1 seed per mini block, press gently into surface (~¼" deep for brassicas). Lettuce: surface-press only — needs light to germinate, don't bury.

environment

Heat mat to 70°F. These are cool-season crops — they don't need tropical heat, but basement temps (60-65°F) slow germination. The mat cuts germination time from 7-10 days to 3-5 days. Rack cover closed around this shelf for humidity. Mini blocks dry fast — check water twice daily.

days 3-5 — watch for sprouts

Once most seeds have sprouted: Move Tray A to Shelf 2. Take it off the heat mat. Open the cover. Lights 2-4" above. Let seedlings grow until first true leaves appear (not the round seed leaves).

days 10-14 — pot up

Select the stockiest seedlings and pot up to 2" blocks. Press fresh 2" blocks, poke a hole in the center, and nest each mini block into it. Keep 27 total (see table above). Compost the runts or give them away. Move potted-up blocks to Shelves 3-5.

Wave 2 — Tomatoes + Friends Mar 28 - Apr 1

setup — 15 min

Press 34 mini blocks into Tray B. 1 seed per mini block. Tomatoes: ¼" deep. Chard: ¼" deep. Parsley: surface press only — parsley needs light to germinate, don't bury it. Label everything.

environment

Heat mat to 80°F — critical for tomatoes. They won't germinate reliably below 70°F. Cover closed. Mini blocks dry fast — check water twice daily. Your Wave 1 brassicas are growing on Shelf 2 or already potted up to 2" blocks on Shelves 3-5.

days 5-10 — staggered sprouting

Tomatoes emerge first (5-7 days), then chard (5-7). Move sprouted minis to Shelf 2. Parsley takes 14-21 days — don't give up on it. Leave parsley mini blocks on the mat or at room temp. They'll come.

days 14-21 — pot up

At first true leaves, select the best and pot up to 2" blocks. Keep 22 total (see table). Tomatoes especially benefit from selection — pick the stockiest, shortest seedlings. Nest each mini block into a fresh 2" block. Move to Shelves 3-5.

Wave 3 — Basil Apr 15-20

setup — 10 min

Press 8 mini blocks. Use a fresh tray or add to Tray B if there's room. 1 seed per mini block, surface press — basil needs light to germinate.

environment

Heat mat to 75-80°F. Basil is tropical — cold soil = no germination. By now your Wave 1 brassicas may be hardening off outside, freeing up shelf space.

days 5-10 — sprouts + pot up

Basil sprouts quickly in warmth. Move off mat once up. At first true leaves, select the best 5 and pot up to 2" blocks. Basil tolerates 2 seedlings per 2" block if you want to keep extras. Keep under lights until transplant in late May.

Heat Mat Rotation

Your single mat works perfectly — waves are staggered so it's never needed in two places at once.

Light & Airflow

Light height is critical. 2-4" above the tallest leaf tip. Raise as seedlings grow. Too far = leggy, weak stems (the #1 indoor failure mode). Too close = rare issue with LEDs but watch for leaf curl.

14-16 hours per day, on a timer. 6am-10pm works well. Seedlings need a dark period — don't run 24/7.

Airflow prevents damping off. Once seedlings emerge, add a small clip fan aimed at the growing shelf. Low speed — gentle leaf movement, not a gale. This also strengthens stems for outdoor life.

Rack cover protocol: Closed around the germination shelf (humidity helps seeds sprout). Open around the growing shelf (airflow prevents fungal disease). If you can't zone the cover per-shelf, prioritize airflow — remove the cover entirely once most seeds have sprouted and rely on bottom watering for moisture.

Basement humidity is your friend. Basements are usually humid enough for soil blocks. If block edges are crumbling or turning pale, lightly mist with a spray bottle. But usually bottom watering handles it.

Daily Check (2 minutes)

Every morning. Fast and simple.

1. Water level. Lift mesh insert — is there water in the solid tray? Add ~¼" if dry. Blocks should feel damp, not soggy. If saturated, let them dry a bit before adding more. Mini blocks dry out much faster than 2" blocks — check twice daily, especially trays on the heat mat.

2. Check for sprouts. Any new seedlings emerging on the germination shelf? Once most are up, move that tray to the growing shelf (lights close, mat off, cover open, fan on).

3. Light height. Seedlings grow fast. Adjust to maintain 2-4" clearance. If stems are stretching and getting thin, the light is too far.

4. Quick disease scan. White fuzz on block surfaces = harmless mold (increase airflow). Seedling collapsed at soil level with a pinched stem = damping off (remove block, increase fan, reduce water). Yellowing lower leaves = overwatering or not enough light.

If Things Go Wrong

Leggy seedlings (tall, thin, floppy): Light is too far or too few hours. Move to 2" above. Confirm 14-16 hrs/day. Can't fix leggy stems, but bury them deeper when transplanting (especially tomatoes — they root from buried stems).

Damping off (seedlings topple at soil line): Fungal — caused by wet + stagnant air. Remove dead seedlings. Increase fan. Reduce watering. Open the cover. Prevention is everything — you can't save a damped-off seedling.

Blocks crumbling or falling apart: Mix was too dry. Re-wet aggressively (should drip freely when squeezed) and re-press. Easier to start over than rescue crumbly blocks.

Nothing germinating after expected time: Check temperature (too cold = slow/no germination for warm-season crops). Check seed age — old seeds lose viability. Paper towel test: 10 seeds in a damp towel in a zip bag on the heat mat. If fewer than 5 sprout in a week, seed is bad.

White mold on block surfaces: Harmless saprophytic fungi feeding on organic matter. Increase airflow. Scrape off if thick. Won't hurt seedlings. Don't panic.

Roots poking out of mini blocks: Time to pot up — don't wait. If you're not ready to select yet, nest the mini block into a 2" block anyway. Circling roots in a tiny block set back growth more than potting up a day early.

Build Sequence

Step 0: Pre-dig (1-2 weeks before)

Call 811 for utility marking. Probe soil along planned perimeter with rebar — check for rock at 12". Mark perimeter with stakes and string, 18-24" out from bed edges. Choose gate location (side closest to house/hose).

Step 1: Dig the Trench (Day 1 morning)

Spec: 12" deep, 6-8" wide, full perimeter (~64 ft).

Recommended: Rent a walk-behind trencher (~$150-200/day from Home Depot Tool Rental or Sunbelt). Does 64 feet in under an hour vs. a full day of manual labor. Warren County has shale and evergreen roots — a trencher handles both. Reserve ahead, spring is busy season.

Manual alternative: Trenching shovel (narrow 4" blade, $35) + mattock ($35) for roots and rock. Budget a full day. Dig in 6" lifts, pile dirt on the outside. Cut tree roots cleanly with loppers — don't rip them.

If you hit rock at 8-10": Compensate with a wider L-apron (18" outward instead of 12"). Doesn't need to be perfect — just needs to defeat a groundhog's dig attempt.

Step 2: Set Posts (Day 1 afternoon)

Drive T-posts every 5-6 feet around the perimeter with a manual post driver. Corner posts go at corners. Gate posts: use two T-posts side by side, or 4×4 wood posts in concrete for stability. Posts go 18-24" into ground, flat nub side facing inward. 14 posts total for a 64' perimeter.

Step 3: Attach Fencing + Apron (Day 2 morning)

Unroll 4' welded wire (2"×4" mesh) along the perimeter. Attach to posts with T-post clips or heavy zip ties every 8-12" vertically. The bottom 12" bends outward at 90° into the trench to form the L-apron — this is the critical anti-dig barrier. If using separate hardware cloth for the apron, overlap it with the vertical fencing by 4-6" and tie together with wire.

Step 4: Wobble Top

Leave the top 12" of fencing unattached to any post or rail. Bend it outward at ~45°. It should flop loosely when pushed. A groundhog climbing the rigid lower section hits this wobbly overhang and can't get leverage to climb over. If your fencing is too rigid to flop, attach a strip of chicken wire at the top extending outward.

Step 5: Backfill Trench

Push piled dirt back over the buried L-apron. Tamp firmly. The apron should be completely covered. Grass will eventually grow over it, locking it in place.

Step 6: Build + Hang Gate

36-40" wide (wheelbarrow width). Frame from 2×4 PT lumber: two stiles + two rails + diagonal brace (bottom hinge side → top latch side to prevent sag). Staple welded wire across frame. Hang with strap hinges, latch with barrel bolt. No gap under the gate — add a wire mesh threshold if needed.

Maintenance

Monthly inspection during growing season. Look for dig marks at the fence line. Add soil over apron if you see attempts. Replace rusted/damaged wire before it becomes a weak point. Check after winter for snow/ice deformation.

Quick Alternative: Temporary Bed Cages

Since your beds are raised 12", you can staple hardware cloth directly to the bed sides extending 3-4' upward as a temporary cage while you build the real fence. Ugly and annoying to work inside, but buys you a few weeks if the real fence isn't done by planting time.

Season-Long Growing Guide

A lazy-but-reasonable maintenance schedule for two raised beds in part shade. Do the bolded tasks, skip the rest if life gets busy. The garden will forgive you.

Ground Rules (Part-Shade Edition)

Water: Shade = slow evaporation. Let the top inch of soil dry between waterings. Stick your finger in — if damp, skip it. Overwatering kills more part-shade gardens than underwatering. When you do water, soak deep, avoid wetting foliage.

Feed light: Less sun = slower growth = less demand. One side-dress of compost or balanced fertilizer mid-season is enough. Don't push nitrogen on tomatoes or you'll get jungle with no fruit.

Harvest often: Greens that get picked stay productive. Greens that sit bolt. Pick outer leaves of lettuce/kale/chard every few days once they're big enough.

Slugs are your #1 pest: Shady + moist = slug paradise. Scatter Sluggo (iron phosphate) around transplants and resow areas. Reapply after rain. That's it — no other pest management is likely needed.

Monthly Schedule

Late March setup

one-time

Prep beds. Top-dress each bed with 2-3" of aged compost, work into top 6". Mix in 5 lbs all-purpose fertilizer + 2 lbs greensand per bed. Run a pH test if you bought one (target 6.0-7.0).

ongoing — daily check

Tend indoor seedlings. Brassicas + lettuce already started. Lights 2-4" above, 14-16 hrs/day. Bottom-water when blocks feel light. Don't let them dry out, don't let them sit in water.

Mar 28 – Apr 1

Start tomatoes, chard, parsley indoors. Same soil block setup. Tomatoes need warmth (70-75°F) to germinate.

April build + sow

Apr 1–15 — one-time

Build groundhog fence. Non-negotiable before anything goes outside. See Fence Build tab.

Apr 10–20

Direct sow cool-season crops in Bed 2. Peas (on trellis, north edge), spinach, arugula, lettuce mix, radishes, beets, carrots (Little Finger), scallions. Water in well, then leave alone — cool soil does the work.

Apr 15–20

Start basil indoors. Needs warmth. Don't rush it outside.

late Apr

Transplant brassicas + kale + chard to beds. Harden off for 5-7 days first (set outside in shade a few hours, increase daily). Use row cover if frost threatens. Scatter Sluggo around transplants.

weekly — 10 min

Walk the beds. Check soil moisture (finger test). Pull any weeds while they're tiny. Check fence perimeter for dig marks.

May transplant + first harvests

early May

Direct sow bush beans in Bed 1 once soil is 60°F+. Also sow scallions if not done in April.

May 20–25

Transplant tomatoes + basil to Bed 1. South edge for tomatoes, 24" apart. Stake or cage immediately — don't wait. Bury tomato stems deep (up to first true leaves). Direct sow cilantro nearby.

late May

First radish harvest! Pull at 1" diameter. Resow the empty spot if you want — or just leave it.

weekly — 15 min

Routine care: Finger-test water (2x/week in hot spells, less in rain). Harvest baby lettuce/arugula outer leaves. Pull weeds. Check for slug damage on transplants — reapply Sluggo after rain.

June growing hard

every 1-2 weeks

Prune tomato suckers. Pinch out side shoots in leaf axils to keep plants to 1-2 leaders. This is the single highest-value 5 minutes you'll spend — more fruit, less disease, in part shade. Also remove lowest leaves touching soil.

early Jun

Resow round 2: lettuce, arugula, radishes in Bed 2 where spring greens bolted. skip-ok — spring sowing still producing?

ongoing

Harvest greens aggressively. Lettuce + spinach bolt fast in June heat. Pick everything usable before flower stalks appear. Kale and chard keep going — just harvest outer leaves.

mid-late Jun

Harvest broccoli main heads. Cut when florets are tight, before yellowing. Leave the plant — it'll produce side shoots for weeks.

weekly — 15 min

Routine: Water deeply 1-2x/week (more in heat waves). Sucker tomatoes. Harvest whatever's ready — beans, greens, radishes. Pull bolted lettuce/spinach.

July peak season

ongoing

Tomato harvest begins! Cherries (Tiny Tim, Red Cherry, Sungold) ripen first. Pick when fully colored. Keep suckering. In part shade, expect later and slower ripening than packet says.

mid Jul

Pull spent peas. They're done. Replant that south-edge Bed 2 space with fall carrots or scallions. skip-ok — just mulch the bare spot

late Jun / early Jul

Resow bush beans round 2. skip-ok if first round is still producing

once

Side-dress tomatoes with a handful of compost or balanced fertilizer per plant once they're setting fruit. Don't overdo it.

weekly — 15 min

Routine: Water, harvest, sucker tomatoes, pull weeds. Check fence. This is the easy part — everything is growing itself.

August harvest + fall prep

ongoing

Peak tomato harvest. Check every 2-3 days. Overripe fruit attracts pests. Pick anything showing color — it'll ripen on the counter.

Aug 1

Start fall brassicas indoors (kale, broccoli, cabbage). Same soil block method. Transplant late Aug / early Sep. skip-ok — ambitious but rewarding

late Aug

Direct sow fall greens: spinach, arugula, lettuce, radishes in Bed 2. Shortening days + cooler nights = prime conditions. skip-ok — but these are easy wins

mid-late Aug

Harvest beets and remaining carrots. Don't leave beets in the ground too long or they get woody.

weekly — 15 min

Routine: Water (less as temps cool), harvest, remove spent plants, compost debris.

September – October fall harvest + wind down

before first frost (~Oct 10-15)

Final tomato harvest. Pick all remaining fruit, even green ones. Green tomatoes ripen in a paper bag on the counter or make fried green tomatoes.

Sep – Oct

Harvest fall greens. Spinach, arugula, lettuce, kale all thrive in cool fall weather. Kale gets sweeter after light frost. Row cover extends the season 2-3 weeks.

Sep

Transplant fall brassicas if you started them in August. They'll produce into November with row cover.

late Oct — one-time

Season close-out: Pull all spent plants. Compost healthy debris (trash anything diseased). Top-dress beds with 1-2" of compost or shredded leaves as winter mulch. Clean and store stakes/cages. Leave fence up — groundhogs don't take winters off.

The Lazy Minimum

If you only do five things all season, do these:

1. Water when dry. Finger in soil, water if top inch is dry. Deep soak, not a sprinkle. 2x/week in summer, less in rain.

2. Sucker tomatoes every week or two. Pinch side shoots. Single biggest return on 5 minutes of effort.

3. Harvest everything the moment it's ready. Leaving ripe produce on the plant signals "stop producing." Pick early, pick often.

4. Scatter Sluggo after rain. 30 seconds, prevents the most likely pest damage in your shady beds.

5. Pull weeds while they're small. One pass a week, 5 minutes. Way easier than dealing with an overgrown bed in July.
