I received a bunch of these seeds (F1's) from a good friend. He missed a male KNK and it pollinated his other strains. Anyway, I sowed 12 of them directly to germinating medium, which is just Espoma seed starter with a small amount of Ocean Forest mixed in, and all 12 of them sprouted and are looking good. Today was their 3rd day of showing true leaves, and they do seem to have that "hybrid vigor" that I've heard about. I have them under a Grow Northern 6 running 18/6. I will either be running Elite Nutrients or CleanGrow. I supposed I have a couple weeks to decide. I have ran into problems with all my of previous grows, and I think most of them were pH related. I thought I could just throw some Dolomite in there, feed with tap water that wasn't pH'd and never have to worry about it. Didn't work so well. Now I pH my water after everything has been mixed and check the runoff from time to time as well. Here's a picture of what we have so far.
