No Chiller... hot room... DTW Coco or Ebb and Flow

[MidnightSun72]

Ok so I am wondering if someone can educated me on whether or not I could do dtw coco setup or an ebb and flow (I'd prefer this I think) with no chiller. Multiple 4x4 rolling tables.

I am using LeD and CO2 and intend on having the room at 80-85*F or or 27-30*C.

So with the room being so hot. And the reservoirs being in the room I assume the water temps would get fairly warm after a day or two in the 80s. I am aware this is an issue for dissolved oxygen levels, can I compensate for this with a strong air pump and air stones? I figure with ebb and flow the roots will get lots of oxygen between floods.

I want to avoid the use of chillers because I would need 6 seperate little chillers because their no room for a big one and a central res without giving up a bunch of cultivation space.

Another idea I had was keeping the room pretty cold at dark cycle like 16*C so that the water has a better chance to cool over night

So I am trying to figure out if it's possible to get away in a hot room with no chiller via cheating with extra air stones etc. Or other methods. .

80-85 is normal, 90 and up is hot. Yes you can run hydro in those conditions without a chiller but alot of that depends on water quality. Lucky for me the tap water in Durham Region is good.

If your thinking of hydro, start reading about sterile or live/bennies methods. In flower I only use shock, no chiller. Veg I still need a chiller.

RDWC...

RDWC...

My tap water comes in at 300+ ppm out of the tap. I think I might use RO.

What's up with ominous RDWC thing. Are you recommending I try that instead? I thought root temps matter even more in RDWC.

I like to do sea of green so I was thinking the ebb and flow or cloth pots filled with coco and perlite in trays same idea as the ebb and flow exactly. And do it that way. But I have no idea what is good really.

I was just stating what style hydro I run but yeah DWC is more likely to get root issues like rot or bacteria.

You can do it easy with ebb flow, especially with res under the table. Run a sterile nutrient mix with some Zone or similar product and use ro water.

300 ppm is perfect to use with regular hard water nutrients
if you RO you need to use soft water formulas .. harder to get

that will be hard to use for small plants that only need a bare minimum of nutes. i don't even feed my flowring plants 300ppm

and i would get an analysis of what's in your water.
