Addition of the HRV is to control humidity? Always thought that would be a good way to bring in outside air to the grow space, without having such an impact on temperature.
Ya I used to use just a blower. Problem is is my vent goes into the roof of my shop and travels to the back end about 25'. In winter when its cold my vent line tends to freeze off even though I wrapped it with insulation. Also makes a huge stalagmite where it drips. My boys found it and had to smash the shit out of it last winter LOL I do run a carbon filter but as you probly know they work good for a bit and then start passing some stink. That's the reason I vent at the back. Gives some time for the smell to diffuse befor getting to the front yard. Im in the country so I don't care but the wif get pissy.
I figure the ventilator will condense most water in it before it goes out. It has 2 cores. I did notice some condensation in the out pipe so I sloped it back the the ventilator, hoping I don't get freeze offs. -20c is when it's starts to going for shit. Then I noticed the vent is not designed for water running back in the out vent so I had to build a trough to get the drip to the core where it has a drain.,always something LOL
The vent isn't 100% efficient so the air coming in is cool and does help with temp. Sure smells nice and fresh in there now, should help.
I'm hoping I can get away with no dehu. or AC during the cold months. Shutting down the flower room for the summer and moving to the greenhouse with light dep this spring. Got to find a nice sativa, veg inside and start flowering in July in the GH.

what's going on with your roots?
Rot issues. Tried bennies, just too expensive in Can to get good ones. And didn't have very good results. Trying sterile this run with pool shock and or H202.
I'm on well and it's 600ppm so I use RO. I'm guessing some bad bugs get by and contaminate my system. Using the UV sterilizer and the odd shot of shock or h2O2 on the new run to see how it goes.
