Hi guys do I need anything to stir my water reservoir to water Coco? I will be 2 weeks away from my growroom and I set up a auto water for my plants. I have a air stone in minimum setting (max is too loud). Do I need anything else to stir ?
Iam using canna a and b and rhizontonic.

nope that'll be plenty. maybe some h202 and a refill to be on the safe side. nice diy halos btw, although it looks like the middle plant escaped XD

have you tested the system before you leave? it took me awhile to find a nute regimen that would remain pH stable for 2 weeks.

Lol I wouldn't bother with a pump at all to be honest. You already heave the air stones which should be enough.

I found Floraflex nutrients (powder) to be really PH stable over a week.

I will keep it like that on a daily basis I will just fill it up with 10 l . When I have holiday I fill it up all the way. Will be 2 weeks hopefully they survive

I think the are slowing down as the winter is getting harder. I have a 55w tube heater and a order another one with 80 w . I will see if I get at least 70f

Well id have it on a timer but It doesn't keep raising temp in a fish tank or in an nft system which it runs 100% of the time.

A pump running in water will raise the temp unless the ambient temperature is low enough to cool the water at a pace faster than the pump can heat the water.

if his res is 26 gallons (or 100 liters). And he uses a small hydroponics pump of 20W. And the water starting temp is 64F (18 Celsius) The water temperature will rise .17 degrees Celsius per hour. So in a day it will go from 18 Celsius to 22*C next day 26*C and the temperature will get hotter faster (less water same thermal input of 20W per hour) as the resevoir gets used up over the two weeks.

I use a setup a lot like this but I use a pump to circulate the solution on a timer that runs 15 minutes every hour. It does heat the water a bit but not bad.
My problem is I can’t find a nutrient that doesn’t smell like shit after a day or more in the res. Good thing my res has a cover cuz my wife would be tossing it out if she smelled it.
I have tried adding chlorine and that helped a lot but I have better results not running sterile in DTW coco. I haven’t noticed any affect to the plants with smelly nutrient water it only affects my nose when I open it.

One would assume their res is not sealed and extremely well insulated.
