what you can do is wrap a dark towel around your res. this will help keep the light out and will help keep the water colder, around 66degrees f. that is a cheap way, or you can buy supplements like hydro guard, kelp, ect. these add on do work, but they are not 100% fool proof, they do help. also make sure you cover your air tubes or use the darker one not the clear. hope that helps you.

I agree with the other grower, hydroguard protects against problems developing from a warm tank.
My res is always at 68°F and my canopy is usually at 78°F. The only thing I need to pull this off was to place my air pump by the vent. Fresh, cooler air is drawn in through the vent and the air pump then pumps it into my res, keeping the res cool. Depends on your setup and the air temp outside of your grow room, but has been super effective for me. I still use hydroguard though.

“hydroguard” from botanicare is your solution. It’s a little pricey but will solve your issue.
I was planning on giving dwc a shot next run

Carbon FilterHello growers!
I'm thinking of removing carbon filter's outter fabric.
It affects my exhaust dramatically.
Does anyone knows if this is going to make it insufficient or ruin it?
(i think that this layer prevents humidity entering carbon particles)

Also do I need to use the carbon filter the whole time?

6" Fan in 3x3 TentI bought a 6" fan for a 3x3 Vivosun tent and I'm noticing a good mount of negative pressure even at the lowest setting. Do I need to get a 4" fan? There are some vents on bottom sides of the tent. Can I use those to lessen the pressure? Thanks!Setup. Ventilation

Temp tent issueNice! Thanks guys for the quick help! I’m also kinda sort of having a temp issue, I’m trying to make it the best I can, I’m way down south and the temp reads 86-88 a lot. If I blast the fans and humidifier it does get down but I’m worried about the electric bill going up.Week 1

So has anybody used these cordless mini dehumidifiers in their grow rooms? They’re small units that u charge over night every so often when the silica changes colour? My grow room is very small so an electric dehumidifier wouldn’t fit and I’m struggling to keep humidity downSetup. Ventilation

Smelly room, with filter should I be able to smell flowering buds?I have a 3x3 grow tent with a 4” fan and filter. The filter is in the tent and exhausts into the room. I taped the filter to the line and line to the fan so no pinhole leaks. The fan is rated for 198 cfm. I have it on low because when it’s high the smell is worse.

Fan vs Fanless LEDsHow effective are heatsink LEDs? I'm not sure if I should go with fanless (like Mars Hydro SP150) or with a fan (Mars Pro II Epistar 120). I struggle with heat, when the tent is closed it gets to 29-30 degrees with humidifier in full swing (HID lights) and I want to close it soonSetup. Lighting
