The only thing that im a little concerned about is what happened when my buddy topped off the pots. Instead of using the rest of the biobizz light mix he used greenlite by roots. This has some nutes in it and i hope it doesn't burn the initial roots. He put about an inch on top of the biobizz. I scraped a hole and pulled up a handful of the biobizz where i planted. Its a noob thing since our first run was tooooo smooth! Also, my buddy is OVER 75 years old, glaucoma and a tumor in the brain but he can smoke reefer like a chimney. Lol, but he does a great job tending to the girls. Funny thing, he almost forgot where he put this batch of seeds we planted. He is why i got us into growing instead of him just buying.
