Oh interesting, maybe the HPS was too strong.. usually you want MH for seedlings.
Yes that is what I did. My ballast can be changed to different wattages. So I ran my 1000w bulb at 600w.. Seems the plants did not like that.. it changed the color spectrum a little bit and was still too bright.
oh damn, maybe some phone sensors do not support it.
Yes, definitely wanted that MH bulb. It had been about a decade since I last grew and somehow forgot I used to have different bulbs for veg and flower 😭 Killed so many plants! Blamed everything from the water to the incubator before realising my error!
Yep sensor, it was a mid range phone when I bought it (Samsung A12) but it's done well, I think the only other thing I wish it could do is automatic focus stacking.
Well hope both our lucks improve soon, it always sucks loosing plants.
If you can get your hands on a MH bulb it may change everything. If I tried growing seedlings under my HPS I would expect problems.
