Are you still vegging these and if so when did you start your lights? I started adding light 7/15 and my seed plants reverted to single leaves but clones only went to three leave. I thought i was a week early starting extra light but I guess not. They were 1-2 feet on average height.The seeded are all C99 crosses and C99 f2s
i noticed the greenhouse was anchored on a pier it looks, is it bolted on or set when the concrete was poured?
I did not add light ... I put some up in case ... Most are sativas and hybrids and my gh gets allot of light ... They have stretched more than I would have liked and will stretch allot more ... Large plants are a month+ old three weeks in the ground ... Small ones are gg4 put in the 16th ... I may add suppulmentry lights to help reduce the stretch but it mostly has to do with the heat.
