The black thing is an inline water filter, keeps my water crystal clear and keeps bad shit out of my water chiller. As for draining the t fitting that dumps water into the epicenter, i hook a hose up to one end and plug the other, drains easily. System is basically an undercurrent 4XL. I flush with tap water while draining to clear everything out. Drain it almost completly. Than i use a small shotvac and suck the remaining out. And refill with ro. Ez pz.
Cool. I started doing some reading about rdwc and that's exactly what other people said too lol. Are those the 2" spin tight bulkheads? How do those work? Does the pvc slip into the bulkhead and the bulkhead has a rubber seal?

I plan on building a few rdwc setups for my new rooms. Doing a soil run right now to see how the rooms environment does. Plan on doing 1st flower room with 2 - 6 pot rdwc setups, 2nd flower room with 4 - 6 pot rdwc setups and veg room with 4 - 6 pot ebb n flow setups. Clones start in the same room as veg using a homemade easy cloner. This should keep me at 72 plants at any given time with a harvest once a month.

Yeah I've grown different ways in the past, been wanting to do some dwc for sometime now. Was going to purchase an under current setup, but after examining them and figuring out how they work decided to build one. Ran me around 300$.

Was going to run spin tight bulkhead bulk heads but at 12 to 14$ ea said fuk that. They have 2" bulk heads on amazon that ran me 4.50$ ea!! And work fine. There's a pic in my first post of a box of them. I am having some small drips here and there, so I suggest using some kind of silicone along side the gasket. The 2" pvc slides into the bulk head and can be glued in place, I didn't glue them and they don't leak. This is kind of a test run. Wanting to run the 13 gal ropak containers after this run.

I was looking at the photo of the bulkheads you showed. I was trying to figure them out. I couldn't tell if there was a rubber seal inside of it or if they are glue on type. I've never seen the spin tech ones but I'm under the assumption that there is an o ring seal inside or the bulkhead that makes a seal around the pvc plumbing so no need for glue.

Yeah there is a rubber seal, make sure you put it on the outside and not the inside. Had a huge 35 gallon leak the first time lol. And its a pretty tight fit for the pvc pipe. Going to glue soon tho.

I'll probably go the same route as you since I'm going to need 78 bulkheads lol. Once my system is built i won't have no need to disassemble it and move it. I will glue the pvc to the bulkhead and use bellow glue on the gaskets that make a seal on the bucket. I used cheapie bulkheads from menards on my chiller reservoir and have been running that for the past month with no leaks but those are in a food grade pickle barrel and only 1" diameter. I'll be ordering part here shortly. I'll start a thread so you can check it out. Maybe we can help each other out lol.

If you don't know what bellow glue is, it's the same glue that's use in boat outdrive to prevent water leaking in from the transom from around rubber bellow boots for the exhaust and shifter cables. It's some bad stuff last 20+ years and is easily removed if need be.

How long do you plan on vegging? I only planned on using around 5 gallon pots which worked for me in normal dwc but I was only vegging for 1 month after clones rooted. The 5 gallons filled with roots pretty well but in the end seemed sufficient for 6-8oz plants. Only thing i ran into problems with was in normal dwc a plant that was at the end of flower plants could take up 4 gallons of water in 3-4 days. So i was constantly topping buckets off with fresh water

I plan on vegging for around 1.5 months, lots of training, only running 2 under a solis tek 1k de hps durning flower. Want to fill in a 6x7' area all tops. Want to pull 1+# per plant is my goal. This tangie i have yielded huge in soil and has the most amazing citrus smell and turned a crazy purple. Think these 8 gal might be enough, possibly going to switch to 13gal when i flower.

Setting up a float valve in the epicenter and connecting it to my ro to automatically top off when needed.

I could see needing the bigger container then if you want 1# per plant. DE lights are bad ass, wish I could run them just don't have the ceiling height. I have a buddy who consistently gets 11-12# per harvest from a 4K watt de room, he's running 10g soil pots and veg for 2 month under t5s. I thought he was talkin shit until I actually seen it lol. He does a sog grow in a 10x10 room. Looks like a mess when it comes to watering, no room to work but those lights are definetly impressive.

Im using the solis tek 600w 6k de mh for veg, i pulled the glass off my ac\de reflector and am no longer air cooling it. Just pulling air out of one end of the room and pulling cool air from the opposite end. Dont have a thermometer in there but its not to warm or cold. Ive got 9ft ceilings, Ive droped the light around 24" and have noticed it burns plants, at 32" its work wonderful. I also emptied about 2.5 gals of water out of system because the bottom of my net pots are too moist and i want them to dry out a little so the roots shoot down in search of water. Almost thinking about draining the entire system and leaving it empty till roots drop out the bottom of the net pot. Or is it ok for the net pots to stay moist about 1 inch up the bottom of the net pot??? Thinking of purchasing another ac/de hood and anoth solis tek ballast and running 6 13 gal after this run ☺

When i was running dwc i would run the about 2" above the bottom net pot so the bottom 2" of hydroton was always in the water. I did that to make sure the clones were getting water and not drying up. It worked for me but I had a ton of air going to my pots, they would actually rumble from the circulation. The pumps I have are something like 9150 liters per hour and 6 something psi. Once the roots made it out of the expanded clay they went nuts, I would then lower the water to 2" below the expanded clay/net pot once the roots were established outside of the net pot.

Im running an ecoplus eco air 7 commercial air pump, makes the tubs boil also, going to see how they respond to being a little dry as i dont want any rot. If i see no diffrence going to flush out system and raise water level when i do a rez change. Im basically hand top feeding them when they look dry with water out of the system until the roots drop.

That's from 2011 lol. I did a couple dwc grows after that and quit growing. Bought a new house and couldn't grow here. just recently purchased my neighbors house so i could start growing again. Just got my rooms built actually doing soil right now to test it out.

They keep my room in check right now buts it's really cold outside. Before turning my co2 generator on i and only running 3 lights i actually had to install a 50k btu furnace in the room to keep it warm enough even with the lights on and fans off
For the lights. You can see the furnace in the 3rd picture. with all the lights on and co2 running it would get 90+ degrees pretty quick. The ice boxes run very little and keep the room at 82 all day long. Don't know how it will be in the summer and chilling reservoirs at the same time. I will probably install a 3 ton central ac unit in the spring to cool the room and let my chiller concentrate on cooling the reservoirs. My main problem was at night my room would drop down to 60 degrees.
