Hiya folks!
Berlin-based grower here, returning to growing after a loooong time. Hooray for the recent legalisation!
I've grown indoor (HID Scrog) and outdoor in the past, bust since I don't smoke, it's been almost 20 years now.
Here are two (Cherry Pie) seedlings, about 2 weeks after I put the seeds straight into soil (just a few hours pre-soaked in water). Broke surface after 3 days, so this is Day 11 above ground.
They are tiny (maybe 2-3 inches) and I decided to repot when their growth basically stopped for a few days. That was a good decision (new growth afterwards) and went well. The roots looked healthy, unexpectedly long and thin actually, with very little lateral growth.
Now they are in a mix of 25% soil, 10% clay pebbles, 10% coffee grounds and the rest coco coir.
Moisture level seems OK now, very fluffy medium and lots of air. Love the coco!
I have a heat mat under the box, hooked up to a temp sensor. Soaked clay pebbles at the bottom of the box.
Rather DIY, but this keeps a very stable, low maintenance environment at 22°C air temperature and 65% (+/-3) humidity.
Soaked the coco with a weak (diluted to 15% of normal dose) nutrient solution before potting, and have that in my spray bottle (no watering needed so far).
I think, initially the pure soil medium was just too compact, hence the decision to repot. Additionally, I might have overdone it with the light, so lightburn could have been another issue.
Now using a (diffused) 4000k / 11w LED at 4-5 inches plus a quantum board dimmed to 30/40% at 20 inches.
Photone tells me around 200 PPFD at plant level.
I removed the dome today which was rather open and ventilated anyway. Medium was not drying off with the dome on, but it wasn't wet either, just fluffy and moist. I don't know how coco retains water, but it seems OK to me.
They look OKish and seem to do better, but the eye test is noticeably on the yellow / pale side.
Solid green in the center / around the veins, but rather pale towards the edges.
Anything I should look out for or check? I'm just watching and waiting, but would rather course-correct early if someone with more experience has any advice.
Cheers & Thanks!
