4" rockwool cubes

What kind of plant would a 4" re cube support? Drip to waste.

Been using coco, looking for an easier medium from clone to flower

works better in ebb and flow. 3 foot plant.

I would stick with coco. Rockwool in top drip is miserable! I moved to coco cause all my babies were water logged all the time. Either stick with the coco or go to ebb and flow if you really want to switch to rockwool

Check out Sure to grow cubes...I hear they're better than rockwol. Personally I use Hydroton in an ebb n flow...its reusable, and you don't have to play games with the PH(set it and forget it).

Kind of a step backwards using Rockworry cubes??? Stick with the Coco. whats the issue, looking for simple. Coco in small pot 6" veg for 4 weeks transplant to 3 gal pot done?? If you got to use them than, Ebb & Flow is the way to go, but there are better ways to grow don't you know, check out some other grows then you will know the answer to the question you pose.

Peace
