Seaweed Extract not clonex , just a spray bottle only a few squirts a day maybe .
I agree with letem grow no ammendments. Seedling require practically nothing but alone time and proper temps. Rh is important but can be overcome. Temps cant. My rh stays in 30-40s. I adjust with watering in veg and flower. Temps i can control easy and keep 80-85 with a drop to 70 lights out. Here is a pic of some photo. Seed to here low rh…sigh…but learned to adjust other factors.
