The pot is 7.5 inches high, say the light fixture on top is custom made and only 3 inches thick , that leaves me around 30 inches of vertical grow space. Most auto-flowering strains run up to 100cm which its roughly 40 inches so I would also need to find the right short enough phenotype to be able to grow her without doing any lst.
That's a good option but it would be more expensive than doing an DIY fixture which is the main point of thus experiment; low cost and maximize yield. That light takes up a good 4, 5 inches of vertical space; a custom light could be as little as 2.Round led......?

That's a great idea. The basic idea for this experiment was to utilize the space as affordably as possible but at the same time giving it the most light from the most angles I can to maximize yield. The goal is to get at least 2-3 ounces from that space; if i go with the strips only set up and it gives me 99 watts; theoretically I can get 3 ounces and not even have to be as efficient as 1 g/w. It would still be a high g/w ratio of around .75g/w, but it wouldn't be impossible.
Id sincerely rec the qb120/qb132 and spread the light out a bit. One qb on max needs more hanging height.
Great insight. So you would use 2 x QB120 for 140w or just the one for 70w? With 2 QB120, one next to each other, would spread the light out more and not be as intense to keep the light closer to the plants correct?
I think they come in 4s? As many as you can, you can even slam one on the side.
I was just thinking 3 of these side by side. They're 11''x 9'' so they would fit just fine and have ample equal lighting across the canopy. It would be 195w total.

Hadn't noticed that was for a 4 pack. With this driver (?) I would run them in series, 2 on top, 2 on the sides, or all 4 on top but placed vertically and they would fit super snug (9'' x 4 = 36'', space is 36'' wide), maybe I could add an extra inch or two to the space to make them fit better.Start with this kit it will end up cheaperQB132 V2 Quantum Boards

Might want to check the meanwell XLG range out, the highest wattage is 240 but they are considerably cheaper, smaller and lighter than the HLG
I totally agree about the space and its ability to blend in. The concept is precisely that; a furniture piece that can be placed within the home and blend in with the rest of the furniture. You can't do that with a grow tent. I'll eventually make a thread about the prototype and gather input from the forum. I have a wood worker doing the piece. About the extraction fan I plan to run it at 60% to reduce noise levels; possibly using a 6 inch fan at 60%. It shouldn't make any noise at all at that level of power id think.
A 6" fan is typically 50db, trust me its not quiet. You can get fans like ac infinity 6" that run at 33db I think.
That's exactly the one I was looking at and yes it runs at only 32dBA. Good too know it can be run at much less power and consume even less electricity and get the job done. Temps shouldn't be an issue since this piece would be inside the home so anywhere between 70-77 f should be the average. Lights wouldn't give off too much heat I would think; maybe add 3 f so 80 f max? A more complex model would include some sort of ambient control including temperature and humidity. Taking it one step at a time though and trying to make it as simple as possible.
The AC infinity has a model that comes with speed controller and one that comes which automatically adjusts with a temp controller or (not and) humidity setting. I imagine that bumps up the cost. But worth it.
I think even this one would be quiet enough at 28 ddBA (at max speed) and it includes temp and humidity controls. The package I had already included in the budget for the build was around $120 with the filter. This would add another $50 to the build with the filter; that's not too bad. Its rated at 200 CFM and I only have around 20 cubic feet; so basically it replaces all the air inside this space every 6 seconds at full speed.

Keep the driver out of your grow space it would be a major cause of heat. If you keep to 150w total and use an ac infinity you should be good. I dont have experience with these boards exactly and even less of stealth. But the boards i use stay quite cool when run at similar power levels and surface area, though youd be running each diode a bit more hot so its hard to say.
That's a good idea to keep it outside somehow. 150w would be good for that space, maybe if I'm able to bring the temps down a bit and place the driver outside somewhere I can get away with 200w for flowering and it would still be at 60% capacity. I'll still run some trial runs before I even put anything in there to gauge the temps at different wattages and such. I'll also be adding a hygrometer that can also be access via app. I'll be building the app from scratch as well, but that's also further down the line. You would also be able to control wattage and/or light intensity form this app as well as timer, alarms and schedules for the lights.
