Hi, I've got easy sativa and frisian dew and I'm, planning on planting in mid april in a micro greenhouse. I'll then be moving them into the ground at the start of may. I'm mixing my own organic soil and i dont want to give my seeds nute burn by putting them in too early. My question is how big should i let them grow before moving them outdoors into the ground. Bare in mind they'll be going from germination to the greenhouse pot then straight into the ground. Cheers, MA2S.
