DWC?

Yes, a chiller is absolutely a great piece of equipment to have,and though I've used them in the past, my water never gets above 67 degrees now so I don't currently use one. With that said, root issues can aabsolutely happen in water temps below 68 and a sterile or bennie res is crucial to avoiding the unknowns. Never add h2o2 and another disinfectant as they cancel each other out and never add h2o2 to a bennie res.

Dude you are absolutely NOT supposed to use Hygrozyme in a DWC Res.

My method: and I have Zero issues with slime:
The foundation: A Chiller. I know this investment is not cost effective for most, but know this: chilled water holds a higher DO( dissolved 02 content) than ambient growroom temperature water. This means that your plants will experience substantially more vigor and explosive growth than room temp reservoirs, and bacteria basically don't stand a chance at colonizing. Chilled for the Win. All other DWC methods are inferior without a chiller. Period.

H202 at 1mL per Litre every couple days. I should note that I simply add this step by default, and have never not used H202 in DWC. I'm of the persuasion that, since my recirculating system is chilled, the H202 isn't necessary, but I have no issues so it remains in the regimen. If it ain't broke..

Water changes. I do a 20% total volume water change weekly.

This routine, in part, stems from another hobby of mine: saltwater aquaria. Water changes and chilled water are a must in that world, and I find them to be pertinent in DWC. The hobbies are very similar, although aquaria is light years ahead of the grow world on water quality techniques and lighting especially.
Good luck.
Yea I understand the water temps with DWC. I Just don't have the want to buy them for all 3 locations I have. I am going to use Reflectics insulation to wrap all of my buckets individually Along with the pvc connecting them and the lids. I'm using all LED lights and without insulationg anything my water was at 68 degrees even colder. So I think I'm good. The clerk at hydro store suggested hygrozyme but obviously just wanted to sell it. I've stopped listening to him anyways lol. I tried the h202 just the kind from Walmart and it looked like it works. I also just did fresh water out the tap which contains some bleach I think vs letting the water sit out for a day. And then I'll add the slightest bit every 3 days to keep the water sterile. This seemed to work too. I just like the way the sm90 bubbled up and the way it smells in there. Sucks I really wanted to use it why you have to show me the cancer stuff lol. Just got my water heater and prob take clones tomro or the next.

ive been looking into this but something isnt clicking ( http://www.hightimes.com/read/how-build-two-bucket-dwc-system )
i understand the concept of this thing but i dont see how this will help the plant if the roots are not even touching the water yet. i know the roots will stretch until they reach what they need but idk... wont the plant die because it doesnt reach the water? i know these plants grow pretty fast, please clear this up for me, thanks
Thats why I don't use dwc anymore. I would basically have to set up my plants in netcups with hyroton on a flood table till roots were coming out the bottom. I might as well just do flood and drain, which is what I currently run. Yeah, you can top feed them manually, or with drip rings. You also need air pumps, air line, mutiple buckets which means mutliple res changes...etc. Its just too much of a hassle especially when its not any better than flood and drain. So my advice about dwc... try it. It will stear you in a better direction but you'll learn in the process.

Yes I never use the two at once but did experiment with h2o2 bleach and sm-90 all on differnt resevoirs. I don't know what part of my General hydropinics line is the benifcial a. Cause I'll just stop using that part of it and using sterilizer. I won't need water chiller but I def want to do sterile over bennies

All on how you set it up. What buckets, net pots, recirculatiing DWC, mine will be so dam simple. Clones into a cloner untill roots are good and long. Then the best 4 into a rdwc system for a month. Doing 60% water change every week possibly. Then into another rdwc sytem to flower. Only maintanence is filling and emptying using water pumps that are there. Just gotta plumb it right. I dump into a trash can on wheels then wheel it to the bathroom drain and dump.

Instead of ditching all the bennies try adding some that work. General Hydroponics Subculture B works great on root problems.

Clones from a cloner still need put into a medium of some kind, the roots will then have to work out of that medium before you can just thrown it in a bucket, or tote, whatever. Your "only" maintenance is what is the bigest pain... emptying and refilling reservoirs. Then you're going to move them into another system? Doesn't sound very simple to me.

I just feel like it's a lot simpler to sterilize than to add beneficialls. From all I've read and reasons I've came to Id rather make it sterile.

The roots will grow a few inches maybe in the mister cloner. Then they'll go into 3" net pots filled with hydroton and put in Lid on 3.5 gallon bucket rdwc undercureent. The water level will cover half of the net pots which will be touching the roots. So they will grow right away. The pumps output has a "y" and goes to a shut off valve with vinyl tube attached to drain the water out into a seperate trash can on wheels when changing nutrients. Easily pump the water into the bathtub. Then reverse to fill the system back up. It's realy easy. For each 4 plant grow cycle im doin I'll have to do this once a week or less. And once in between grows fill with bleach water and it cleans itself. Pump it out and wipe down and good to go. Seems like a pain in the ass but the whole reason for all of my grow if so I can do the least amount of work per week as possible

I only use subculture b or hydroguard when I think there's a problem. Other than that, nothing as far as h2o2 or bleach, thats for sure.

Come time to move from veg to flower is a pain for me cause their in differnt rooms. But not a biggie. Just pick up each plant and lid and set It on a bucket and carry into the other room x4. If I could have put them all next to each other I would have.

Yea a lot of people would never try bleach. But the amounts im gonna use are so small it keeps the water with around the same amount of bleach that's in your tap water.

Each to his own. I'm just a little lazier lol

You just have to keep adding things like h2o2 and bleach because the oxygen "boils off" Bennies are just add and forget.

I am too I have a body full of injuries and tries to make it sinple. Was gonna do flood table but I have height limits so couldn't. It will take me about 20 minutes to empty and shop vac the leftover bleach water for cleaning and then wipe clean after it dries. I'm trying to make it to where I don't have to do any res changes at all or clean systems except for at the end of veg and end of flower. Lucas formula? Something like that. I just don't know how yet. Will need one month of veg and 2-3 months of flower. If I could even just get away with doing one nute change during flower would be sweet. Whatcha think

Exactly^^ that's what I'm doin with the bleach. Keeping it at a certain level. But with bennies you can still run only problems. And I just don't want to risk it. You can have problems both ways but still... Just how my Brans a tickin

I know there are people who can, or have, used one reservoir the whole grow but you're still adding water and nutrients do to the plants feeding/drinking and evaporational loses. Not sure how they do it exactly?You're in the same place I am, constantly thinking of ways to simplify and make more econmical. I'm still trying to perfect my flood and drain setup but every time I change something i see something else. Its endless lol

Yea it really is endless. I hope it slows down at least. Too much work to be lazy. Bduddhbssjz. Lol i think the lucas formula would work but I can't grasp it yet. I was thinking that or just watering every 3rd watering with 1/2 strength nutes and plain water the rest of the time. And checking ppm. When it's drops too low I'll water with a light nute mix. But this part seems like I'll contantly be mixing up batches of a 10 part nute. Just gotta get a few grows under my belt and it'll come to me. I've onlt budded and completed one plant. But I've been researching for years like it was my job. I'm obsessed with making the most efficient easiest grow

Nice! That's alot of fun! Haha not. I got tired of it. I worked a summer job for a while putting up and taking down and relocating etc coral reef tanks. Pain in the ass fuckin job but it was a lot a lot of fun.
