I think I over or under watered and murdered most of my seedlings. (I usually start with rooted clones) Going to try this schedule now with new beans and want to make sure it seems fine with you guys before I do it. I know this is more art than science but does this look like we're in the right ballpark here?
If anyone has a sure fire method that has worked over time please let me know!
STAGE 1: JUST SPROUTED (Days 1–5)
Water
~50–100 ml (a few tablespoons)
Soil should be:
Slightly moist NOT wet or heavy
Light
18–20 hours/day
LED: 24–30 inches away, low intensity (25–40%)
Too much light = stress
Too little = stretching
STAGE 2: EARLY SEEDLING (Days 5–14)
Water
75–150 ml per watering
Let top 1 inch dry before watering again
Light
Same schedule (18/6 or 20/4)
Slightly closer light if they stretch
STAGE 3: ESTABLISHED SEEDLING (Weeks 2–3)
Now roots are forming.
Water
150–300 ml
Wider circle, approaching full pot gradually
Every 2–3 days
OR
Day 8 → ~750 ml every few days
Day 14 → ~1 liter
(Adjust based on pot size)
Light
Increase intensity slightly
Still not blasting them (PPFD ~200–400)
STAGE 4: ROOTED / CLONE-LIKE (Week 3+)
Now they can actually drink.
Water
Full watering (until slight runoff)
Then WAIT until pot gets light
Usually every 2–4 days
Light
Full veg lighting now
Lower light distance gradually

~50–100 ml (a few tablespoons)
- Small ring around stem (not soaking whole pot)
- Every 2–3 days (not daily unless super dry)
Slightly moist NOT wet or heavy
18–20 hours/day
LED: 24–30 inches away, low intensity (25–40%)
75–150 ml per watering
- Still watering in a ring, expanding outward
- Every 2–4 days
Same schedule (18/6 or 20/4)
