So I have 2 cuttings that are in 6 inch rockwool cubes, the roots are starting to grow out the sides. Both are going to be mother plants. I was wondering what kind of container would be best to transplant to. They are in a 2x4 tray with a drip system under 4 4ft T5s I was thinkin maybe coco pete pots but wasnt sure if the roots would grow out the sides of those too. or would plastic be the best bet? any input is greatly appreciated! Thanks CG goers!
