High water temperature

Hi all,
Question I recently purchased aquarium thermometer. And my water temps are 75-78 I don’t have the extra cash to invest in water chiller. I am running hydroguard. Should I be adding a ice packs to drop temps down ? Or is that going to hurt my roots?

Ice packs are a good way to fight root rot, however it will become a challenge when the plant gets bigger. And if you are doing any LST with magnetic hooks and wire, it will be hard to take them down every time you rotate a iced bottle in the reservoir.

I hear you bro. Thanks for the feedback.Just worried since I seen temp that high.

Yeah, I totally get it. My rez was 80F when I was rotating iced water bottles in my rez every hour. Was not fun and causes the PH to drift like crazy. I gave in and got myself a chiller.

Also as long as the ice packs are in thick plastic like a soft drink bottle, it shouldn’t shock the roots.

What I did to make sure the ice packs did not touch the roots was by taping a stick on the bottom of my lid to keep the bottle floating only to the left of the reservoir

@AandM-farms,

Will the grow be okay during power interuptions/ outages?

Maintain your temperature. If it is in the middle of winter, cover your unit with a blanket. If it’s too hot, consider moving the unit to a cooler location like the basement.

Decrease night temps for colour change

Several strains of cannabis in the purple family (Grand Daddy Purps, Purple Kush) will actually show the colour purple in the leaves and bud. Although most of this is accomplished through genetics, having the temperature cool at night (16 degrees celcius area) will help the purple develop. Be careful though, too low of a temperature can slow or stop growth completely. In my home during the summer, the basement is much cooler than other parts of the house. Is it worth draining, moving and refilling the Grobo to get awesome purple buds? Yeah, quite possibly.
