My Stealth Cupboard

Hey gang, I've been lurking and asking questions for a while now so I thought I'd share the system I've come up with. This is my second grow in this cupboard and far more successful so far.

I'm growing a Sativa dominant and have mainlined it so only 8 big colas coming off it. She's in week 9 of flower.

The cupboard is 650mm wide x 600mm deep and 1400mm from the shelf the pot sits on to the ceiling. Grow height from the pot could only be a practical maximum of around 750-800mm to allow room for the lights. The 2 exhaust fans in the ceiling are actually 4, with another one on top of each of those on the outside which then go through a filter. In the bottom left rear of the grow area (hidden by the front left corner of the pot) is the intake. I have a fan on the inside then on the outside is a small radiator (for a liquid cooled computer setup) and another fan. The outside fan pulls air in from outside the building and pushes it through the radiator while the inside fan pulls it into the cupboard. The radiator is plumbed to a pump in a reservoir and another pump in the reservoir circulates the reservoir water through an aquarium chiller. The bulb hanging down on the left side of the pot is an IR heating bulb. There's a 150mm oscillating fan and 450w LED lights. In the "window" on the left is a humidifier and a dehumidifier. Timers control the light and feed schedule and 2 Inkbird systems control temperature and humidity.

The system is an ebb and flow type (I guess) with a 15 litre reservoir under the shelf and the plant growing in perlite in a 15 litre pot which sits in a second "drain/return" pot.

Awesome setup. Very clean and well thought out. Appreciate the share. One little suggestion, consider straightening the exhaust duct hose. This could help with less air restriction (no bends) or less stress on the fan. Also, not obstruct light. It looks like both are getting hit with light and thats for your plant! This won't make or break your plant by all means just something observed.

Thanks again for sharing your build.

Thanks. I ran the exhaust hoses like that to try and pull out the heat from the lights and it works pretty well. I’ll try some adjusting tho

It's not too bad in there this time of year but It can get pretty warm in there in summer as I'm pulling air in from outside. I'm limited on space (and my electricity bill!!) so can't go a larger aquarium chiller

You have the ducts sucking from below the light but the heat comes out the top where the fans are built in the light.
If you struggle with heat later then just tape them over the fans and get the heat out directly.
I did it that was as I'm limited in height and the plant was getting very close to the light. The heat coming off the lights was enough to start burning the plant so I tried ducting it the way I have. I didn't think to mess with it in this grow. I'll suss out later and see how much heat's coming from the fans
