Temperature and dwc...

[Tarallo]

hello to all users of the forum, sorry for my english .. I was planning my second cycle but due to high temperatures do not know start with the dwc system or return to soil .... my first question are the temperatures where I live in summer also get to 40C, I would have problems with root rot ...?
Tanks to all

Safe operating temperature for water in DWC is below 75F with approximately 65F-68F being appropriate for optimal dissolved oxygen in the system.

If you grow room is getting to 104F (40C) then not only will you need a chiller for you DWC, you will need an Air Conditioner to ensure your plants don't die or at the very least are extremely stressed due to excessive heat.

Hope that helps.

Those temps are mean. DWC would never work. The plants would also not survive that temp at all. If they did the buds would be air puffs

yeah, man unless you're working with a very small amount of water > 5 gallons then DWC is not an option. The ambient temperature + the heat coming from the lamp. You can try with 100% success a soilless grow. I recommend biobuzz soilless. It a halfway point between dirt DWC. you water it daily, with a ph 5.8 like in hydro. great results.

you could of course build a DIY chiller since we're operating under the assumption that you are unable or unwilling to buy and operate a normal water chiller. have you looked at the water cooler diy chillers guys have built?

If you do decide to do a DWC regardless of your high temps, be sure to add H2O2 (hydrogen peroxide) to your reservoir. It is an antibacterial (helps against root rot) and allows more oxygen to be dissolved in the water.

I highly recommend dutchmaster zone instead of h202. monochloramine.I've personally tried h202 and it can be used to address a specific problem but as a preventative I do not think its as effective or as safe. to each their own not knockin the advice you were just given but felt strongly enough bout it to post..
