Check out my video on Super Recirculating Deep Water Culture SRDWC would love some feedback from the pros!

Do you even need the air stones, then? Too much DO is toxic to plants. Just wondering if you've tried a waterfall effect vs. the return submerged without air stones?

No air stone. Shes been in the same pickle jar for a few months. 5.5 feet tall. I do need to water her twice a day, and I never let more than an inch of water collect in the bottom. Not exactly DWC, probably more like a manual drip system.

^^^ That's quite impressive. Kind of like the elementary school project of rooting a potato in a mason jar. Has she been in natural light or indoor? Nutrients? Do you have some true DWC, etc. going on in that room behind the plant? When are you going to flower her, or is she a mother?

She has been inside in my veg room. She is one of three Lemon Skunk mothers I have. Gonna flower her for christmas. I give her the same nutes I feed my other plants. My mothers are in DWC, I veg ebb and flow, I flower drip.
I have a thread in hydroponics section "my ghetto grow... revised"

I put 1/2" dia. elbow fittings in the lids of all my tuffbox tubsites last year, and everything has thrived ever since.

Water to feed those fittings comes down a manifold from the one and only pump, sitting in the control bucket which draws water from the rest of the system to feed these waterfalls.

My biggest individual is currently 2 1/2# ( roughly 1100g), I think I have another going now that will beat that figure.

How 'bout this DWC dome? Won't be long now...

is it just me or are the pictures on the orginal post not working

Anything from Sqydro will come up like that. For some reason, must be the way he posted them, but all his great threads aren't as helpful without his pictures.


Edit; Hes not around to my knowledge but I remember posts back in the day (2011/2012?)

im trying to find a guide on building a rwdc on here, i see them on youtube, I need stuff in writing to know what to buy

His pictures dont show up because the site crashed on 2012 or so and all pictures were erased that werent hotlinked from another website.

Why go through all of this hassle and just go with a RDWC undercurrent and in the controlling tank you have one end of your inline pond pump sucking in the water to the controlling tank and then hook up a venturi injector into your controller. Now you have oxygenated water, no water falling sound, circulating water so no stagnation and silent.

You could. I know MOST venturi injectors generate bigger bubbles than what is most ideal for oxygenating the water. I personally like the sound of falling water however I still use an overrated air pump.

This is a two bucket rdwc [no air stones, or submersible water pumps] ,with a reservoir and optional resupply reservoir.. You can raise the water level in the buckets in the beginning to keep the hydroton as wet as you want it... You can even use an air stone if you feel the need.
This setup will work with only a single air pump.. A small air pump will pump enough air to work a single GH pumping column.. You avoid the ton of heat you can get from a big air pump and a bunch of air stones....... The gh pumping column can be used with/without the drip ring since it's under the lid....

This is made possible with the use of a standing column of water in the grow bucket... This water column is connected directly to the reservoir, so the water level in the water column is the same as the maintained water level in the reservoir... As the water is pumped into the grow bucket from the standing water column, gravity returns it to the reservoir to keep the two water levels the same... A GH pumping column moves about 5-6 gals an hour so the pump out and return flows stay the same.. No flooding or uneven water levels in the buckets..
All the parts for the standing water column were bought at HD... The pvc column is thin wall 3/4, a trimmed down tomato cage is used for a scrog screen support... Simple zip tie works to attach any kind of stiff screen... I used a rubber coated 2x4" screen.. Don't try to bend the tomato cage legs out at the weld, they'll break every time. Bend about 3/4" above the weld...
Leave home without worrying about water levels while you're gone...
