What also really helps with Temps in DWC or RDWC is placing the buckets directly on a tile or concrete floor. Can't beat the heat transfer. 68 to 70 consistently. Love the videos!

Old Mini Bar fridges can be modified into chillers!. 2 holes 1 water pump and a roll of tubing.. A large old fridge could be setup to chill a bunch of systems. Find older 1's for cheap even free online ready for some mod's. Works great, you get a chiller and grow room snack bar in 1 ;). Heaps of DIY info online about them.

[@diegomontoya796]

Small chest freezer with bad top seal. Never worked as a freezer. Perfect with a thermal switch and the resievor.

Good video man . The cooling of the water is whats keeping me from get my DWC going I’ll probably wait till winter because I’m a tight ass don’t wanna spend the money lol but I see a grower using a fish tank cooler can’t remember the channel but it work good I think 16 gal a hour was what it do for around 130 not bad and one grow you’d pay for it . Happy growing and happy Birthdays man !!

[@DusaFarms]

Appreciate it fam and yea I’m thinking about running DWC in winter only to cut back on energy consumption

[@timbaker5988]

I've got an RDWC system, and agree temps of the nutrients has always been an issue for my system. One thing that works for me cause I'm very small... I went out and bought a refrigerated cooler plumbed in as my reservoir, which I plug in and it helps to maintain the temp of the nutrients. Doesn't make a huge difference, but I figure it's a problem that can have many solutions, which when taken in combination, can overcome the problem. I've had very good results with this approach.

[@toastiesburned9929]

i put my bucket in a storage container half full with water and I threw small bottles of water in the bigger container. it started out to keep the ice away from the roots, but it also gives a larger thermal mass without needing a larger reservoir of nutrients.

[@DusaFarms]

Smart! Appreciate it fam

[@toastiesburned9929]

Between that and beneficial microbes, I've had no problems. Right at lights on I would add some, and when I got home from work I'd add some more. Idc if it wasn't perfect, it doesn't have to be 😉

[@karegairegi9071]

"TRUST ME!" Reverse your exhaust system... Place your exhaust fan near your AC vent. Run your ducting through the bottom of your tent. Place your pump directly in front of the ducting, then you're going to place as much of the tubing into the duct, including the air manifold if possible. The core problem isn't room temperature per say, the main problem is that the majority of the hot air that's heating up the water is coming from the air pump. Focus 100% on cooling your "AIR MANIFOLD" & the tubing at the beginning of the air manifold. I literally kept my water temperature at optimal with this method. The only drawback is based around the location of your grow being that that area would have to be running the AC 24/7!

[@DusaFarms]

Solid video. Just validated a few things that I’m planning on changing up for my next run.

[@bobbyedstrom5688]

FYI, I went with the cheap $120 water chiller, 1 it had trouble reaching 20⁰c (68⁰f) 4 site + res (13 gallons) and with in a week it failed, the cooling fan would randomly stop and with in a few hours the water temp would reach 27⁰c (80⁰f). I bought the Vevor 53 gallon for $230 and that thing kicks some serious butt.

[@markrich3271]

I love my water chillers . Truth is I only use them in flower in summer. Grab huge pond pump and pond style air stones / diffusers.

[@carlosfranco281]

Running 1-5 gallon bucket and trying to grow in a closet in the Texas summer. Water temps were waaay too high. Got a water chiller from Walmart for $110.00. It's basically a small aquarium chiller. Works great. Unfortunately, I still can't get my seedlings in rockwool to take off even after 2 weeks. My flower is struggling and it's my 1st grow, so we'll see what happens.

[@DusaFarms]

I always struggle with rockwool as well. I usually just germinate my seeds in paper towels and then place the taproot into the clay pebbles

[@freesmokegrows]

Use the Paper towel method like dusa said and wait until your tap root is at least 1 inch long before putting it In your rockwool cube

[@StNick-ri9pz]

@@freesmokegrows This method is what works best for me

[@freesmokegrows]

@@StNick-ri9pz also once you get your seedling "with the one inch tap root" transferred into the rockwool cube, put the rockwool in some type of humidity dome. Then let the tape root grow a quarter out the bottom of the rockwool before placing it into the bucket. This allows your root to continue growing this time towards the water at the bottom of your Hydrobucket.

[@shannonclaywell8144]

Try to bring the PH down in the rockwool, it tends to have a higher acid level

You can also put your air pump near the cool air intake or outside the tent to suck in and pump cool air into your rez

[@Ballme60]

I figured out why my comments weren't being posted!! Buy a used water cooler off market place ( $15- $35 ), one that you would normally put a 5 gal jug in the top. Now tear it apart so that you are left with the compressor and the cooling coil. Some of the cooling coils are coated in a protective plastic and some are not. If the one you have doesn't have a protective coating on it just wrap a plastic bag around the coil so you don't get any oxidation in your nutrients. Place the coil directly into your nutrient reservoir. Buy a device that will monitor your water temp. I use the ITC-308 ($50). Plug the compressor into the cooling plug on the device and set your water temps. I set my water temp at 67 deg and set the turn on temp at +2 deg (69).

[@jameshicks2446]

Ok I'm running DWC 5 gallon res (STYROFOAM) under a 315 w LEC built in ballast. 1. Add ice to nutrient solution after mixing but before final pH balance.or brake it down to 5 milk jugs and put them in the fridge for a bit . These 2 things will ensure you start off with optimum temp solution. 2. This is most important when controlling and maintaining the air temperature coning I threw your pump ..you gotta have your pumps in front of a fan and best if that fan is ducted to an AC 3.this is RARE tip that maintain temp in your res for long periods of time like this for me eliminates my need for a chiller I will only have to chill my solution at the start of each res change ...... STYROFOAM STYROFOAM STYROFOAM STYROFOAM STYROFOAM STYROFOAM ICE CHEST lined with a industrial strength black garbage bag It is the absolute best insulator and the black garbage bag allows 0.00% of light penetration to the roots ... 4 . enjoy your smoke and a little bit less stress growing ....

[@--OpT.OuT--]

I think you're definitely right.

[@sidecardude]

forget styrofoam, use an actual beer cooler for a nutrient reserve, or 2 inch insulation on top and inbetween the nutrient tanks. Ice helps, no nutrients, just a block of ice once a day......, I also use foam spray insulation around the tubes for the roots!

Nice video, for me, fan-ice daily-across the pump that pumps air into the plant sites. Only way I have been able to get around buying a water chiller, is by chilling the air at the pump intake site, and it is only marginally better than just saying fk it. Running hydro and not pushing for perfection is not the thing in my opinion though.

[@7032rt]

The reason you must have your nutes at 65 to 70 degrees is because if your nutes go higher than 70 is to prevent root rot, and no matter how good your pump is, if your nutes go higher than 70 degrees you will get root rot. I use 5 gallon igloo water coolers for the plants, and a big 27 gallon igloo ice chest for the reservoir , and use a small old fridge as a chiller and if needed ,frozen water bottles in the reservoir to control temps to grow outdoors during summer. Also, I use big air stones in each planter, and 2 in the reservoir

[@jasonwempe3232]

This has not been my experience. I've done over 50 runs now and my res temps get into the mid 70s all the time. 10 watts of power per plant is more than enough to prevent root rot. Most people run little aquarium pumps which are only about 3 or 4 watts. Amazon has 40 watt pumps for under $40.

[@williamcassidy685]

What about taking a small aluminum radiator brand new that was never used. Tie it into your circulation line then mount a fan on it to cool the water.

I just built a peltier cooler for a total of 15 bucks, great for 1 or 2 buckets but not practical for rdwc.

[@IcannaHelp]

Black buckets... Black as we know attract heat, I started using home depot orange and lowes blue even white buckets never had an issue with light leaks. Another tip like you said making ur reservior larger. If you bought pre made dwc buckets that have the grommet elbow and usually blue tinted tube as a water level gauge. Connecting one bucket to another will double your rez size now u won't have the ease of turning one sideways to drain simply place ur plant I'm and empty clean bucket while u drain and clean for your rez change or simply disconnect If you have the ability to just let them drain where they are. You can also place a small pump in the extra bucket and pump it out then refill in the same bucket so u dont even need to mess with the bucket ur plant is in. Yes you will have about an inch or so left on the bottom don't worry it won't harm anything if u are worried use a shopvac for that last 1/2-1 gallon.

[@Graciemay3083]

I just bought a 4 bucket dwc with drip rings by Vivosun. I haven't set it up yet. I'm wondering how or if it is possible to convert it to a rdwc. Any thoughts? Great videos and info!

[@toastiesburned9929]

You need a bunch of pipes and pumps and another bucket for a reservoir and a water chiller, it's a bit of work, and there are videos on how to do it, but not impossible.

[@robertlussier2944]

I got that system for my son. I think you could get a central bucket, and connect it to the four grow buckets with 3/4" to 1" drains, using barbed plastic connectors, rubber hose, and grommets for going through the buckets. Drill your holes 1/2" from the bottom of each bucket, and connect them to the central bucket. Since they use the air lift to the drip rings, they will draw from the central reservoir bucket. You can do all your pH checks and TDS, and nutrient changes from the central reservoir and won't have to disturb the plants. Draw a picture of how you want to connect everything first, and you will know what supplies to get. You could also just connect the four buckets together by a drain, and use one of them for your reservoir, growing 3 plants. When I do my grows, 3 usually fills my 4x4, and is what my state says is legal, anyway. So far I've harvested enough from each grow to keep me in smoke and cannabutter until my next crop is done, and I'm a pretty heavy user.😂

Hey bro, reddit?

[@the_gold_canopy]

If running separate DWC buckets, the best way to keep the temps in the green zone is invest in insulated buckets, or use bucket jackets, and install micro chiller probes, such as Nova Tech Coolworks Ice Probe and temp controllers. Typically sold by aquarium suppliers. I use one in my aeroponic cloner, works amazing! For RDWC it's no question, a minimum 1/13 HP aquarium chiller, 1/10 is the best way to go. Invest in quality chiller brands, stay away from the cheap chinese chillers, especially the electric ones. 🧊

Chillers are to expensive. There are much cheaper ways to cool the water to a steady 66-68 deg.
