Really small DWC/hydro

Can you see where I can go with this? We're in design phase so you're only seeing a mock up. I figured there was no way I could do DWC or hydro in my little tent. Not enough space for equipment or growth.
Sevina was draining after getting molasses'ed, draining into a peanut butter container. This 18oz cup challenge has taught me oodles about roots. Right after a dab, of course, I went to check the draining. It flashed on me I could use same/same duel style design cups to try DWC/h in the same/same molasses draining setup. As roots grow out of the cups I can trim them to keep them from getting root bound.
Darkening the containers. Proper nutes. I got all that. Is it me or could this actually work? No net pots. No 'proper' equipment except water and air pumps. Dwarf strains or short vegged bagseed/feminized.

That's very cool, and I'm subbed to see how it goes.

But just so you know (in case you're not being facetial), you could easily fit (2) 5-gallon buckets or 7 gallon totes for normal DWC in a 2 x 3 tent, and grow 2 small-medium bushes, like most autos.

But I still want to see what you can grow in those PB jars.

Cuz you stoned.
 
I figured I could do that @DingusKahn. Silly as it sounds, I don't want plants that grow too big. I have a maximum height of 24". With the right training and light cycle, I can grow a 4' plant: 2' out, 2' up, which is pretty good size. Problems I would face are a whole new kit of DWC gear, horizontal spread instead of vertical, fitting my body inside the tent do tend the setup. And other prohibitions. All I need for this are the smallest air pump, water pump, tubing, and something to darken the containers. Less than $25, I imagine.
Yes, I was stoned.
 
I was envisioning as much in my head. But think about a plant that size a maturity, and then REALISTICALLY envision how many of those can fit comfortably in your 2x3 tent. I'm coming up with 1 1/2 of the plants that you plant on growing. So you can either veg 2 plants for 3-4 weeks or 1 plant for 5-7 weeks.

Either way, you can veg them to about 10 inches high, bending them down and training them into some sort of flat canopy that fills your 6 square feet.
 
Damn, that really would make a killer DWC-SOG. Prolly close to a pound, if you're any good and you have a nice light. I think I might have to try one of those in my 2x4 with 315LEC. Hmmmmm.......
 
A water pump will heat up that small amount of water really quickly. An aquarium chiller would help keep the water temps in check.
 
A question about water pumps and gallons per minute. The smallest water pump I can find, after a good solid three minutes of googling, pumps 100 gallons. Maximum liquid capacity in my setup would be in the one gallon range. That's a ballpark. 100 gallons sounds way too much. Will this size pump work for my little setup?
How about setting up a gravity fed nutrient feeder? Like a gerbil water bottle with hoses to the plants.
I like where this is going.
 
If you've been following one of the other threads that discussed top feed, you might remember that some have been finding that top feed is not worth the effort. Just keep your reservoir filled to within about a half inch (2-3cm if you're unamerican) and the bubbles will keep everything happy.
 
Man, I've got all these soil grows coming on line, I'm going to have to make room in my flower tent for a dedicated big tank grow. Hmmm.. gotta make some changes.....

I'm doing this!
 
Don't do it SoOrbudgal ! It's a trick! You're a 'merican! An imperial girl! Toker1 means well. If someone throws out that metric crap, ask them to please convert. And if they give you any lip, remind them who you are.
 
Hey Toker1 about that water cooling thing. I know these would probably give me some humidity issues.
1. Terra cotta pots. Natural water coolers.
2. I have a one or two gallon glass jar in initial planning. I'm thinking about a glass full of water? Is it cooler?
3. Would a smaller container cool faster/easier than plastic or other?
4. Air circulation across the water to help cool it?
5. Natural cooling as water/ferts travel through several smaller containers?
6. Run through a secondary reservoir before or after the pump like a cooling pond?
 
I think the pump will out perform any natural cooling pots. Adding heat to the medium.
A larger body of water will be closer to your ambient temps than a smaller body of water would be.
No, larger surface area containers will cool faster than smaller surface area ones will.
Yes, air blown across the water/container will help in the cooling process.
Yes, a second reservoir would mean more water/surface area. This will increase cooling...assuming you don’t need to increase the pump size to make this physically happen. Good to note: Placing the system/reservoir on a concrete floor will pull some of the heat out.
 
How about a metal coil running through a separate reservoir? Seriously. Think Graham Condenser without the cool water pump. Think moonshine still thumper(?) without the constant flow of an outside source of cool water. Aspects of both are interesting.
 
I saw a 70gph pump at my local hardware store. Noticed that the output can be adjusted. I read into that like a fan. The more resistance, the more heat. If I guess I have 1.25 gallons combined, of nutes/water reservoir in the pnut butter containers, a 70gph wouldn't be out of line as far as how powerful the thing is.
