My cannabi seed just open ,and I'm confused of what to do after I put it on Rockwood,should put it under the light or on the Rockwood seed kit on a dark room and wait unti I see the leaves?
what do you intend to do with it in rockwool? if you dont know this basic shit, hydroponics are not for you, you gotta put the seed in soil. cover it with a thin layer (less than half an inch) of soil, keep it moist for the first week and then start letting it dry out between waterings. if you choose a good soil (and you should!), you wont have to add fertilizers for at least a month. edit: oh yeah, you need to throw a lot of light at seedlings right from the moment they penetrate the growing medium, otherwise they will use their stored energy to grow very stretched weak stems instead of good stems and leaves.
I'd flush it and then read some guides. No offense, but you have to have some inclination To read a little before you decide to grow plants.
