Nutrient solution temps.

Cannabis roots aren't so forgiving in DWC when temps get too hot. I'd keep the nutrient reservoirs below 70 degrees F to avoid issues. Just my take.

 

Hey if you have already done it , what's there to talk about ....
Right, fuck the books and what other well know
Hydro growers suggest.

 

Try using "search" for reservoir temps.

 

So you could "search" for other members who might join your discussion and you might just find other threads that already cover your subject, which has been and at length.

My advice is: if you are doing RDWC, get a chiller or a way to get you res temp to 63deg F or one degree above the dew point (so you don't form pools of condensation).

The lowest I have known anyone to grow at had a res temp that was 56deg F.

 

Here is a very good read:

Nutrient Solution Temperature

This explains it:

Simply Hydroponics - Nutrient Temp

 

My point is ever book I have read about growing cannabis in a hydroponic , areoponic or dwc system have a recommended operating temperature.
If you can keep the grow room temp about 70 degrees f your dwc water temp normally run 3 degrees above ambient temperature.

 

I was in the hospital for almost two months.
That plant was everything but dead
I am going to go a head and put it In flowering today

Plant is about 4 months old
Dont have the heart to toss it
It's a little big for a grow tent
Normally I only grow 2 sativa per 4x8 tent
This time it's two amnesia haze ( sativa ) and one berry white indica/sativa hybrid

 

Chillers cost.
Everything cost money .
Growing indoors can require allot of money or investment .
I have about 4k invested into each growing tent .
Not including central A/C. , R O water system plus a fiberglass pressure tank , plus a security system.
