Haha, well, thank you!
Oh, I've done it, and I'm not afraid to do it, but I still prefer to transplant things, when I can, before the roots get too long. Just less to worry about as I have damaged roots this way before.
I'm confident in my skills, though I feel like I'm learning every day, too.
Sup dude,
I still am using my diy ebb gravity drain controller. Its the simplest tool, perfect for mums and super easy to maintain. I use it for raising seed stock for potential mums.
This pic is a great representation. I have two good mums to the left and a couple wannabe mums to the right. Good mother selection takes time.
I try to keep 2 to 4 mums at a time and rotate them out with new stock, always looking for miss perfect, something better, something easier, stronger, the list goes on. Nothing like a good change up.
Great picture and post. I really like how you have that all set up! I wish I had more room like that, but I'm working with such a tiny space to veg. I admire your process for sorting out and selecting good mums.
I set out to make a controller like you did today, but went a little different direction due to the space and size of the space. Too much OG Kush tonight, I can't tell if I came up with something good or godawful, haha.
I made a little system out of little rubbermaid totes, but I initially put too strong of a pump on it, and the pump was filling faster than the overflow/level fitting could keep up with (I think I used a 396gph pump that I had).
In the end I settled on an experimental set-up. I set them up so that they can be flooded periodically, but they don't fully drain. They will flood, then drain to 1" below the netpots, and leave standing water that will have air diffusers in it. So, primarily DWC, but there will be periodic floods that will serve to feed the whole rootzone, and recirculate the water at the same time. The mock-up worked good, now I'm just lightproofing them. Sort of a frankenstein mix of Ebb n Gro and DWC, haha. Hopefully it'll grow plants!
I added a riser to the lower drain on this (not in the pic), so that it keeps enough water/nutes for air diffusers between floods. The riser puts them about an inch below the netcups during DWC use, and the floods will fill up to the top of the "netting" on the netpots.
This was me mocking things up to test it before lightproofing stuff. Eventually there will be 3 of these on the shelf. I had extra lids, so I did some with one hole for a netpot, some with 2, etc. Dremel tool came in handy to modify the bakers rack shelves. These all drain back to a main, remote reservoir. The periodic floods will actually also cause circulation with the main reservoir, as the floods come up from the bottom, and eventually out the overflow back to the reservoir. After the flood, the DWC will contain freshly circulated nutes.
DWC when not flooding:
If you look close, this is the flooded state
I decided to change things a bit. I didn't like the plumbing on the bottom (got in the way of the reservoirs underneath too much). So, I decided to use the first container more like a controller, and put the plumbing on the front of them down the line - a bit more like a traditional ebb/flow sort of thing. I'll probably still keep airstones and may still try running it like a DWC with periodic floods -- we'll see. 
My system is low matenence and coordinates with my ebb ngrow. Your system is completely different bro. Its a hybrid and maybe a 150gph on the pump or lower. I use a old powerhead left behind from when my hobby was fish instead of plants. Good luck on the diy. I'm a big diy fan myself. Ain't nothing like trying to improve the mousetrap lol.
Check out this pic of a undercurrent system. Its a big setup lol. That's 4 inch pipe.
