Rockwool size/plant sizeI 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?1y ago

Otherwise mature flowers during flush. New foxtails white pistils. Harvest?Death bubba week 10 of bloom, in flush. All pistils were orange but now lots of foxtail are appearing, with bright white pistils. Harvest in 6 days but if new pistils are still white should I wait? Trich cloudy, I am unable to get in close with a lupe to see how much amber.

Leaf necrosisWhat's going on with mk Ultra? It gets Neem every 2-3 days, and I have tried to keep pH down to 6. This has been going on since I got the clone, and it continues to happen. The pink kush (last pic) has a few similar spots.
Lights are 50cm above.

Peltier dehumidifier @300ml per day adequate for 3x3x6 tent? Alternatively, a conventional dehumidifier outside the tent?Peltier thermoelectric dehumidifiers extract 300ml of water per day. Weak compared to compresser units, small and use less energy. Is it enough?
Would a conventional dehumidifier set outside of the tent near the intake be effective, or does it need to be inside the tent to work2y ago
