2 months agoGrow Talk So I’ve been using cheapo, black felt-ish one gallon bags from Amazon for my Dutch Table/SoG thing. I just watched a Canna Cribs video and saw them using, what I now know to be, Panda Film bags. Anyone else growing this style (lots of tops, quick turn around) that has used them? 50 for $9!!! Hell yes! Any drawbacks or limitations?
Now to find drip heads I can shove in an inch or two under the coco and sub irrigate. Trying to keep everything clean and neat and be as efficient as possible… on a small scale.

I’ve used the 3 gallon panda film bags before. I had good success with them and would recommend. I wasn’t doing Dutch table. But they should work well for that. They have holes at the bottom. Good luck 👍

You can flood/drain with flood tables to sub irrigate. Drip lines are a tangled mess with numbers. Traditional flood systems with inert media like rockwool required as much of the media be submerged as possible as the media itself doesn’t hold nutrition. Coco doesn’t need to be flooded deep if the flood cycle is long enough for capillary action to wick moisture up.

@jmystro Early morning yard sale score! Two of them for $15 and they hold water. I can stand on them, upside down, without caving them in. I’m 6’5″ and 220 so I believe they’ll work to hold 12-18 1 gallon bags, huh? I’ll build a rack to hold it and figure out a drain spigot of some sort today. Any resources you would point me to for bettering my understanding of the flood table way? I’m assuming I’ll need a pump from the res and one to waste/collection? Check valves for back flow maybe a float that will kill the pump if it fills too much? I can build a logic circuit to control it all with a Raspberry Pi and can CNC or 3D print damn near anything. Jeez… this plant has me wanting to come out of retirement and go find a job at a grower, just to play with it all day.

Flood and drain is simple. Couple fittings, a small pump and timer. One fitting with breaker head, connects hose to pump in reservoir. Other fitting goes to overfill tube to adjust flood height and recirculate back to reservoir.

Hose and small pump.

@jmystro Kick ass!! I was looking for just such a thing and had no idea what to call it!! I’m tripping on “return to reservoir” I was starting to question my thinking… “that’s gonna cost a fortune in nutrition!” Hallelujah!! 🤣 It’s starts to click into place.
My wife’s an accountant for a huge greenhouse company here and I keep begging her to let me meet some growers but the place is ultra right and the stigma runs deep. They buy trees from us so we don’t want my obvious questions to jeopardize that relationship or her position. They did sell me a couple of cubic yards of coarse perlite a few weeks ago and were wondering how I’d use it for tree propagation. 🤣I believe this technique will undoubtedly spill over into our fruit and pepper grows that are coming indoors this fall. I’ve got a couple of hundred free square feet to fill in one of the outbuildings anyways. 🤘🏼
