My Grand Daddy Purple AF seedling seems really stunted. At day 10 past emergence she still only has the first true leaves with the tiniest second set starting (2nd set < 1mm across). [seedling_day10] Light: GE LED grow floodlight on 18/6 timer, reads 240 PPFD on phone app, I’ve successfully grown…

Thanks for the feedback @dirtydave @Flitme @OGIncognito @Dexterado . I put a humidity dome on top until my USB mini humidifier arrives, then I’ll try the humdifier so I can monitor the RH. The potting soil and seed starter mix I’m using has a dry pH around 6.5 but the jug of spring water I was usi…

I have a couple of stunted Gelato Aotos; I believe it’s due to low humidity.

Pics? I purposely did not use domes like @Hellraiser this grow just to see if I could get seedlings through dry winter heat without them. I do use a humidifier that is misting near the leaves but rarely can get my tent above 45%rh. Soil, ph, and temp play the biggest role in seedlings imo. [202301…

Thanks again to everyone who gave advice! Six days later, I’ve corrected the pH and started using a humidity dome. I measured the pH of a tap water soil slurry (I have a Hanna pH pen) at 6.9, which is inside the zone I see recommended everywhere. The humidity dome has kept the soil moist for 6 days…

What’s the temps in the grow space? Low temps can stall seedling growth. 78-82 are ideal :love_you_gesture:

The thermometer reads 73F when the grow light is on. ILGM’s own grow guide says the seedling temperature range is 68F - 77F with the optimum at 73F. [image] Cannabis Seedling Stages, Our How-to Care Guide - ILGM Cannabis seedlings require the right amount of water, light, and nutrients.…

Your call but if you get the temps I posted you’ll see some growth :love_you_gesture:

Seems like you’re forcing seeds to grow in a crappy soil mix and blaming it on the seeds. Maybe try regular soil before wasting seeds on that mix. Who recommended you mix that?
