Does anyone here place their carbon filter on the bottom of your tent?

Thinking about saving 1FT of vertical space in my growtent so i don't have to worry about LST my plants to my scrog.
 
I don’t, but I see no reason it wouldn’t work. I probably will now(especially if stretch gets outta hand) that’s a good idea thanks. :blsmoke:
 
I suggested this a while back but no takers, in colder climates the air coming in the ducts is cold and it can chill the pot area and be a problem (for me) keeping below the scrog canopy warm enough, if i flipped it upside down as suggested I'd have cooler air hitting the lights 1st and getting a chance to heat up, obviously with led the canopy temperature would need monitoring to begin with.

Cold air sinking can dealt with using fans but cold air under a scrog canopy inside a tent is a different problem.

I would use a greenhoue tube heater between the pots,
 
i just changed the filter placement. feels good to have more vertical space for my lights so i don't have to constantly LST my plants into the scrog during the stretch (week 3). i had some leaves start getting burnt because i couldn't raise my light anymore.

That's the thing it's money, money money, I'm using a tube heater and dehumidifier in flower.

Any heat generated gets drawn every minute or so +/- controlling humidity.

to be replaced by air only a little less humid when heated, around 50% of my outlay is on heating and humidity control.

I brought a fan speed controller for my rvk fan,

500w heater on 9am -9pm 18c
600w hps and 450w led on at night
Under the 600w its 30c and under the leds its 25c
The environment temps and humidity is really important.

I made an environment controller with 2 stage variable night/day speeds and 3 fixed idle speeds, 2 relays and two variacs made me a full spec hybrid controller for peanuts, environment is the no1 factor imo.
 
Filter will work anywhere since all air goes through filter before it leaves.
Keeping soil mix warm will make for happy growing also.
