I should be getting some VFT seeds tomarrow and I will be putting them under my grow lights. I have these questions. What is the minimal soil depth and how long should I keep them under the light. Last time I tried seeds I started them by my window and they grew but in the spring I took them outside and they died. I think they just burned and being so young they just died. I'm either going to put them on peat moss and sand or just on some New Zealand LFS. If I do the LFS then the depth is only going to be about a inch and a half.
