Rockwool size/plant size
VitaManstarted grow question 3 months ago
I have a recirculating drip system. Works great
Other than starting seeds I don't have experience with rockwool.
How large a plant can be grown in a 4×4×4" block? Can 3 of them fill my 3×3 tent?
Alternatively, what size block is good for a 9 plant Sea of Green in that tent?

4x4x4" block is only taking up 16 square inches.
a 3x3 foot tent has 1,296 square inches.
You could fit 81 4x4x4" cubes in the tent,
Try aiming for a bigger cube. like 6"x6"x6" or 8"x8"x8" or 12"x12"x12"

You'd probable be better off with the clay pebbles and coco mix with a drip system. If you really want to use roakwool then you maybe better with a 12ltr,4gal pot full of cubes whcih is how I used to do it 20yrs ago before I stated using coco.They say you can grow huge plants in very little rockwool but its mainly done with NFT System and a mat.
