I never thought of that. That's a good idea. I have a bedroom here that's not being used and my hydro system is for 4 plants so it wouldn't be no problem. I'm thinking I could get 4 more hydro baskets fill with clay pellets and use the small rockwool cubes for the cuttings. If I can slow their growth down I would then place the baskets into the hydro buckets. I could probably cut holes in a piece of plywood to put over the baskets to protect the roots from the light until they're ready.
