Completed a grow in sealed grow room back in 2022. The last time I grew was in 2005 with HPS and open loop system.
Flower yield was 400g + sugar leaves, for a total of roughly 1 lbs, give or take.
the chamber was small, no bigger than 8x8. It was experimental, with the goal of maximising yield off of one plant.
I kept all equipment in the room, including the nute reservoir. There is no lung room.
No air was actively pulled in or exhausted.

Equipment:
- Inverter AC unit, 1hp
- Mini Propane Co2 generator with sensor and controller
- Spider Farmer SF4000 430w (upgraded from the blurple in the pic)
- Dehumidifier
- Humidifier
- The fastest reading pH and ppm meters I could afford
- AC pump unit to drain out coco waste
- No pesticide was used
Grow Method:
- Coco with automated watering and drainage.
- Mainline + lollipop
- 79f day cycle temp, 74f night
- Favorable outcome, but Mainlining still took too much time during vegetative phase.
- Co2 does not shorten vegetative and flowering times. Senescence is delayed if Co2 is not tapered off towards the end.
- Co2 spiked to 2000+ppm when working in the chamber. Co2 remained high after leaving.
- Use of Co2 generator was moderate - about 14lbs of propane was used throughout the grow.
- Ambient climate is hot and humid. Needed gruntier dehumidifier despite running AC.
- Coco is messy. Automating the drainage of waste nutrient took a bit of ingenuity. DWC is still my preferred style.
- Cal-Mag issue was pronounced. Plant stayed healthy, otherwise.
