hey, i just went to the nearest hydroponics store and picked up stuff for my next grow. For rockwool, you will need nutrients in the water? or can you just water it without nutrients and it will grow the same as in soil?
they do have specials, like buy 3 nirvana packs and get 1 free nirvana pack, i think you get to choose it too. When i buy my seeds its gonna be them or seed boutique
