Unfortunately that one was definitely dead and I honestly feel a little bad for it's suffering. Pretty sure the initial over watering and a 300 watt LED made sure she never stood a chance. Pulled it out after it was completely yellow and falling. Most of the taproot grew curved to the side and was brown.
I have followed advice of previous posts and put 2 60w 2700 CFLs about two inches away on a Jack Herer photo fem. It was already germinated and I planted, taproot down, today. Medium is a seed starter made of coco coir in the same peat pot, but I did use the bigger one. Not much bigger. Watered right before I put the seed in. Will be checking soil a little closer this time and not deciding to water by how it looks on the surface.
Taproot curled on this one too and I'm not sure why that keeps happening. Didn't attempt to straighten per advice of this site. Chose start in soil with peat pots to reduce transplanting difficulties. This taproot wasn't as long to start though so it might do better even though it's curved. I am using a wet paper towel in a sandwich bag. Then it goes into the peat pot, watered first, just under the surface. Then a couple drops of water. This is now under the two 60 watt 2700, only ones available at the store. Hopefully tomorrow evening or so it'll be popping up!
