So, I planted 6 seeds in plastic cups yesterday, and I have them sitting on the windowsill while they sprout. Once they get big enough, I am going to transfer them to 4 gallon pots in the grow closet and turn the lights on. I am a little worried that I might damage the roots doing this, though. So what is the safest way to transfer a 1-2 week old plant into the big pots?
