Rockwool block sizes / plant sizes / 3×3×6' space
VitaManstarted grow question 1y ago
No irrelevant responses about other medium this time!
I succeed with drip hydroton and coco. 3'×3'×6' tent.
Exploring rockwool as a mediums for (4×bushy indica) and (9×single cola SOG)
I can get 3×3, 4×4×2.5, 4×4×4, and 6×6 blocks. What do you recommend?

I don't think it's really gonna matter.
Whatever makes sense for your setup. If you're growing a plant of any size, even the 6x6 will probably need to be anchored in some way or the plants trellised to keep them from falling over. Personally I don't even like rockwool as a starter cube, pretty sure I'd hate it as a primary media. Good luck.

Moss in 2nd weekHey everyone,
What should be the next course of action as moss has grown on the plants in the past two days (and it seems likely that the pH level is excessively acidic - source the internet)?

Did I need to size up to larger rockwool cubes?Geminated seeds in 1x1x1 rockwool cubes. End state is to be in 5 gallon buckets with 8" net pot and clay pebbles. I figured the roots are too small to reach all the way into water solution still so put small cubes into 4x4x4 rockwool. Did I need to use larger cubes?4y ago
