4 ft x 3 feet 9 inch. Wall to wall with branches touching all sides. 3 plants. The one in front was started almost 2 weeks later because I had baby plants dying off from gnats. Lost 9 good seeds. I know I have some discoloration I flushed yesterday from nute buildup. I wasn't pushing enough clean water. They wanted food so they got fed every watering. Daily. I flushed 10 gal 7.0 water through 4 gal soil in 5 gal buckets. Runoff looked like coffee. Flushed til it was clear. Had clawing and burn spots in a few leaves so I just jumped n flushed. End of flush runoff was 6.6-6.8. I'm new to all this. Used to just throwing some dirt in a hole outside. But that's not option anymore as I'm in a city. Oh 9 ft ceiling. Lights at about 7-1/2. T5 with veg and bloom bulbs staggered with 600w led to kick a bit.
Oh I am putting 22 inch t5s on walls with 2700k bulbs to sidelight. I have intake under the plants and exhaust above my head exhaust goes straight outside filtered through moth balls. . Slotted raised floor with oscillating fan blowing upward oscillating. Temps stay mid 70s but humidity is in 60s need to get that lower but a ton of steaming hot days with thunderstorms lately.
If your talking to me I did cut all small branches with single nugs. There are very few left I might try to clone. Most of what's there are budding all the way up stem. I'm installing my sidelighting today. For under canopy. I'm adding 2700k t5s to the led strips.
I know it's dark. Wont the t5s under the canopy help though. I'm new so still learning. I'm putting t5s right below the led strips in my pic.
No no facing up. The sun don't face up so I will put on side walls just below canopy. I just put them in flat against the wall. They do add light. Pointing straight out sideways.
