sorry pretty new with rockwool and ive read the fourms about it but didnt seem to get the answers i was looking for thanks for any info people can throw at me.

Welcome growpimp. It's been a few years since I've used RW cubes but I remember how to do it. Soak your cubes in pH 5.0 water for 24 hours (RW is very high pH so you have to go very low to counteract that) before putting your seeds in it, or better yet, germ them in a paper towel first then drop them into the RW. Don't use nutes at all for at least a week, then you can start off with 1/4 strength nutes after they are a week old. You'll go up to 1/2 strength after a couple of weeks, then on to full strength after another week. I'm assuming you're using the little plugs and putting them in the 3" cubes; you will have roots coming out the bottom within a week so keep tabs on that. You won't be actually "transplanting" them, just adding the plugs to the cubes.

yes. rinse the shit outa that rockwool! then soak them in whatever solution you want. for seeds just water is fine, for seedlings (a week on or so), i would recommend 1/4th nutrient strength, if that. weak is good with plants. at such a young age, youll want a wide variety of nutes, N for growth, P for rooting, and a lil of everything else. but go weak, they need time to adjust.

thanks alot guys i was wondering if i could use x nutrients with super thrieve to
