So I'm using ffof mixed with 50% perlite for my seedling germinating now I'm using a 150 hps light how far should I have it when it breaks the soil an should I but it under the light before it breaks the soil?
I wouldn't use or ups to start off your seedling, it will grow very leggy. And wouldn't really have it running wasting electric. If you are unable to run my or cfl then I'd keep it about 2/3 feet away from the new seedling, an watch or temps. Good luck
