Questions about deep water culture

So I’ve been looking threw a few threads and deep water culture is definitely catching my eye but a big question I’ve been asking myself is if you’re plants are constantly in water how do they not drowned? Any info on this topic is very much welcome hoping to learn the basics! :v::green_heart:

The air from the aquarium/air pump keeps the roots from drowning. The water is so oxygenated they don’t rot.

So essentially the plants are only taking in what they need? What would happen if you was to say relocate them would they go into shock because they have been acustom to being in water constantly?

That I’m unsure of because the root ball is just hanging in water, i wouldn’t try to transplant it after growing.
Not sure you could get the net basket off the trunk either

So it would have to be a fixed set up until crop time then? :weary:

Yes but if you had it in say a 5gal bucket you could move it around just disconnecting the air hose. One thing about the dwc though. If your air pump dies/breaks your plant is probably dead by the time you know.

AHH so requires alot more attention, sounds temperamental

Yea I did the 5 gal bucket for years. It’s a bit more work when you do full water changes but the plus is when you have it dialed in you can leave it for long weekends without having to worry about watering (or under or over watering in general). If you get a deficiency you can easily adjust. The trick is to keep it simple as possible. I did Lucas formula using just maxibloom powder (and an occasional scoop of epsom salt). Very ph stable. People tend to make it crazy complicated. Got really amazing results.

Like anything requires more attention at first then it becomes routine. I top off res and check and adjust pH daily (maybe 5 mins a plant). I do res changes as needed (not every 7-10 days as rec). I run the hose for air pump through top next to net pot and lift plant and stone from one bucket to new one with fresh nutes. Sometimes plants get too big and I just top of res (not uncommon to feed gallon a day). It all depends what appeals to us. I also grow in soil and coco. When your retired and daytime tv is the option rather be in the tents.

i used dwc for years until i switched to rockwool. i can now leave out of town for 10 days without question so much better than with dwc for someone who isnt around all the time or who doesnt want to check on the girls all the time.
says the guy with wifi timers and wifi cameras. lol

Oxygen saturation increases as temperature decreases. If you are in a consistently hot environment, keeping the dissolved oxygen high and mitigating root rot can be a challenge. Some folk will cool the solution using a chiller similar to what is used for salt-water aquariums.

I’d say rdwc is one of the more complex solutions that can produce significant advantages but you have to be willing to tweak your set-up and be prepared ahead of time for things that could go wrong. Broken pumps, extended power-outages, infection, flooding, etc.

Conversely, from my perspective, the simplest solution is a soil media.

Once you get everything dialed in, it gets so easy…I turned my Phototrons in to SWC…

Phototrons…SWC/TRON

Water roots will not drown when submerged and only absorb water and nutrients through the root tips. Normal roots cannot handle being submerged in water and would drown if kept in water too long, but they absorb water and nutrients from the whole root, not just the root tip like with water roots.

I’ve found my air pumps off, after what must have been an extended period of time, because I had no clue when it could have been disabled, and the plants were fine. I assumed I was just lucky, but it did make me wonder.
