Drip system as many as 5x per day. Crazy fast growth. If you can automate your watering you will be able to spend more time training, pruning troubleshooting issues etc.
Had a gorilla grow that was boat/canoe access only. A cousin dropped me off so i could water. He proceeded to go back to my cottage and drink all my booze then pass out hard. I had to swim at night 1/2 km in my underwear to the nearest island, steal a boat (temporarily) to get back to my place...
I usually grow less plants than this but I am trying a more SOG approach this round. Well rooted clones were let veg for 4 days then flipped to 12/12.
The picture is at day 21 of 12/12. You can see that near the lower section there is a lot of developing bud sites.
My fear is that this turns...
Composite would definitely be better. I figured I could replace these every couple of years. We get lots of snow and -40F here. I use this to cool year round so the snow always melts around the unit.
This is a massive endeavor.
1. For walls, how about, spray foam, osb, puck board.
2. 3 tons seams light for a sealed room with that many lights.
3. Based on my experience I think you would require 500-600 ppd of dehumidification.
I run 4 lights over a 5x16 table in a very similar setup to yours. Right now I have 210 pints of dehumidification and sometimes it barely keeps up. Shocked me.
