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.
They can grow to any size until you want to put them into the ground, but makes sure that you have enough soil for the root to grow in before you plant them into the ground. If you want to mainly grow them in the ground you can plant them when there around 3-6 inches.
