deep water culture

Running a sterile rez works too. I find that using hypochlorite works well. This is found in Clear Rez and UC Roots. It kills all bacteria good and bad in your rez but you have to add every 3-5 days.

Water chiller is a good option. If you run wort chillers with them you wont have to worry about nutes clogging it up. Its an investment but then you can keep your water temps where you want. 74 is pythium city (root rot). I have even had it show up in 70 degree water. Ideal is 65. Theres a difference between plants surviving and plants thriving.

Look into a good zyme too. Older plant roots die off no matter how healthy they are. Its just part of the game. Enzymes will break down the dying and dead root material back in to food. This is important because if those dead roots stay around too long they are a perfect environment for pythium to thrive.

Do NOT run enzymes in DWC/RDWC. You will regret it.

Why do you say that?

pathogens feed off of enzymes.

The enzymes will do their work and create a sludge on the surface. This sludge is an excellent breeding ground for pathogens.

There was 8 DWC containers one little 6 pot Emily's garden SWC and about 4 or 5 three gallon pots with soil.. look closer, lol..

They were individual dwc pots without a controller, they were drinking so much water that I didn't need to drain them.. I just kept topping them off. Some of them look like shit, because I went out of town and the AC failed on me and the co2 burner got to hot and fried some of them.. But even when I ran tables I never changed the water.. I guess as long as the pH isnt fluctuating and my water temps were good, I was good.. But RDWC is different and easier to change the rez because of the sub pump..

It was never a issue with cost just my laziness..

Well I just have4 5 gallon buckets made for dwc. They all came with their own air pump and their own rockwool+ their own little Brown pebbles with holes all over them, I don't know exactly what they are called. Lava rocks? I'm Not for sure. But I know I gotta wash the FUCK out of them when it comes to starting new crops, other wise the plant gets some kind of mildew on their roots, or a slime, seems to be on the rocksvat the end of each grow, my friend says that it's a helpful alge I don't know about all that. Lol. I don't like the smiley feeling

I don't even think it's a desirable tactic. I mean, how much are your plants worth, compared to an extra batch of nutes?

I use dry nutrient salts. A full hundred gallon changeout costs me a buck or two.

My price isn't bad at all I'm a member of a homegrown club. So I get 30% off every purchase, plus I get points from each purchase and when I get to 100$ I get a free box of 12 grade A high primo nutes. So I think it's worth it, and the free box is huge. I get 2 liters of grow nutes, and root nutes, also reg nutes such as cal mag, and a few other nutes that you use through the whole grow process, then I get 1 liter of a bloom nute, and bud big, umm and a few others you only use during the bloom or budding phase, and they are awsome nutes and if I play my cards rite I usually get them to last me almost a full year, I have gotten this deal twice, second time I just spent 180$ with them to get the points I needed for the free nutes.. Lol. But it's worth it to me, they are excellent high quality expensive nutes, but these nutes are (hippie) made, not by any big stupid corporate government run by certain stupid standards or laws, they are the best nutes I have ever bought, and even better grade A nutes for free, and yes they actually come in what look like recycled soda bottles of 2 and 1 litre bottles, but i don't care, I'm Not paying for some stupid name brand bullspit, or a pretty bottle. The do have pretty cool tops that you get taped to the bottle as a poor once you take the cap off the other cap breaks the seal.
