co2

What does everybody use for a little extra co2 in the tent? And do you have it going all the time or just when the fans are off? May be very stupid questions but I have never used it before

Hello all-- What environmental controllers does everyone like? SWIM would like to select a controller with the option of CO2 control for room to upgrade later on. Maybe something with a built-in PPM meter maybe. I've looked at HTGsupply website (all super expensive or too low end). I also...

I'm almost done setting up 8x10 and 12x15 rooms. So far, the rooms are sealed with spray foam insulation, dehumidifiers, and a mini split is installed. I'm trying to figure out how to provide CO2 in the best way possible. I want to use burners, but I'm reading discussions where people have...

I was gonna start a grow Jan 3 anyway, I’m in. Should be a good one, I don’t have to flower after only 25 days now on a short time window with my grad school break. Strain: -Moby Dick by Dinafem, Photoperiod. probably will only fit 3-4 plants but if 5 is manageable I’ll do 5 fem seeds. My grow...

Welcome to a side-by-side dwc grow in 4x4s with clones of four strains: Green Crack, Jack Herer, Original Glue (GG4), and Trainwreck One 4x4 will have two timber 48sams (equiv of eight hlg288s) with supplemental red hlg35, growbright far red bar, t5 uvb, and CO2. The other 4x4 will have six...

Hi, I have access to a freezer that goes down to -80 degrees C (-112 degrees F) My question is: will this be better or overkill for winterization compared to higher temperatures like -25 degrees C (-13F)? I had heard that I could lose the cannabinoids at this low temperature, they might also...

So I’m considering using a carbon filter on a timer set to switch between on/off every hour to control the humidity in my veg room because I need to use the dehumidifier that was in that room elsewhere. Does anyone know if this will affect the room negatively by lowering the CO2 levels in...

What's up guys, So I'm finishing up a new 5x5 tent setup, so far I have all my bases covered equipment wise - I just have this possible option nagging me in the back of my mind. Long story short I live in a hot, humid fucking climate - this week in October temps ranged high 80s - 90 day, mid...

During Flower, on for the first 3 weeks I add CO2 at 1200PPM and gradually reduce it as the. Weeks in flower progress. So here’s my question, my exhaust fan is off during this time and my temps are let to drift up to to around 85F (cob led running ~1200 micro moles on the canopy) and I do my...

Live from Portland Oregon Strain: Tardis (OregonDieselxTimeWreck) 5 seeds sprouted and are Regular. According to the local farm, regular seeds are more hardy in their genetic line compared to feminised, which may stand to reason. Let’s wait and see. Light: Timber Grow Lights Vero v7 redwood...

Whats up, i am running a sealed room. I have a power vent in the ceiling to prevent ethylene build up. I Run the vent continuously during the dark cycle (no CO2 to waste) but my question is, should i run the vent at any point during the photo period? i don't want to waste CO2, but I am afraid...

I plan a 2x2x5 hi-rise tent, adjustable speed inline 4" exhaust, and Hydro crunch 2' 4 bulb T5 H.O fixture to start. How can co2 build up if exhaust fans are always on? Was looking at co2 dispenser canisters from TNB Naturals, supposed to last 2 weeks or more. Is it worth it to provide co2 if...

Hello Rollitup. Long time grower, new member. I need help. i am running CO2 at 1500ppm and 82 degrees for veg. i am about to go into bud. usually I drop the temp a little for bud, but I know to get the full effect of my CO2 i have to run a higher temp. So my question is, if I am at 82 degrees...

Setting up for a 4x4 grow, under a pair of Timber 48SAMS, a pair of HLG QB-35s, single 4’ Agromax T-5 uva-b, and a single 4’ GrowBright far-red initiatiator. Will be doing ~ 65 DLI, with CO2, and these mainlined NYC Diesels and Super Silver Hazes: as soon as they hit 12” height. Wish me luck!

Temps have sky rocketed and room is suffering, plants look fine i run co2 about 2500 ppm usually temps are around 78-80 but cant get temps down due to exterrior heat witht he extra heat should i turn co2 up a bit or let it ride and watch for heat stress ? They are 3 weeks into flower.

Hi guys building my new co2 system I've got 20pnd bottle with regulator n solenoid. I bought a 5mitre 10mm gas hose that I want to split in two with a tee fitting n block both ends, ive drilled small holes pointing down and they have been fixed above lights. Does anyone have experience with...

A few details: I live on the bay in CA at sea - level, maritime layer leads to temperate climate most days and nights of the year. I have a 10' X 10' room on the second story, with a nice 8' X 4' southerly window. 90% of the center part of the window is covered with thin, blue curtain that...

I have previously been growing in a tent with a floor area of 1 m² under 8 x cxb 3590´s and 2x HLG-240H-C1750B drivers with potentiometers disconnected for max wattage and light levels. I´m now thinking of buying a smaller flowering tent, measuring 125 x 65 x 120 cm. I have been looking at...

I had added a few co2 bags to a few of my previous grows. I had two given to me by a friend. I haven't really had consistent genetics till now. The same buddy sent me a co2 kit that he didn't need and I would like to see if it will really help my specific setup. I know it is relative to few...

So I'm considering switching to a sealed room this summer to help prevent sucking out my A/C faster than I can make it. I run an organic soil water only garden, and I would only be considering running CO2 at atmospheric levels for my room (probably have it ramp to 500ppm and shut off, and...
