Sugar, water and some yeast in a soda bottle with a balloon on top with a pin hole in the balloon so the CO2 can get to the plant

Skip over the bags. They are bullshit. ✌️😁

In my house (1800 sq ft) with my large family (wife and 5 young kids) the average ppm is over 1000 with the low being 900 and high being about 1500 ppm I have 2 4×2 tents in my master bedroom. I regularly check co2 and it’s always over 1000ppm even in the tents. Both tents fully circulating air with inline intake and exhaust fans.

Consistency is key. Plants are not happy with CO2 levels fluctuating in a wide range. This is why you need a way to control the levels. Would you want to be in a room with oxygen levels that fluctuate below what you need randomly throughout the day? Hell no. You can get an AC Infinity CO2 controller for around 100 bucks. There is no excuse to mess with gimmicks. Mushroom bags are a joke that no serious grower should consider.

Commercial facilities regularly turn down CO2 at lights off and we humans certainly do handle varying conditions. So that’s just wrong across the board.

Plants don’t take in CO2 during the dark cycle. Any quality controller has a photocell.

I also disagree with everything here.

@jmystro you suck!!😆😆😆

Do you know like… anything about these plants. Jeez.🙄

Much love bro. It’s hard to be a mod.

Co2 can be a huge upgrade… If it’s the yield limiting factor. When light, temp, humidity, co2, water and feeding are all synced up, growth is insane! The trick is to balance the other variables and make sure you’ve got enough light so the plants can fix that carbon from the co2 with stomata wide open.

Here’s what I would buy…

$120 CO2 Controller from AC Infinity https://a.co/d/4K4qjzv

$45 VIVOSUN Hydroponics CO2 Regulator Emitter System with Solenoid Valve Flowmeter for Grow Room Grow Tent Garden

https://a.co/d/5zGTrwQ

$100 deposit $25 refills for a 20lbs co2 tank from any welding supply store like General Air or similar.

For under $300 give it a try and see how long a tank lasts. I bet it lasts a while. You don’t have to go crazy with the ppm. Even dialing it upto 800 will have a big impact.

I think you’re better off buying the tank and regulator once, instead of $40 mushroom bags every harvest. I don’t think the mushroom bags work very well imo.

@scottyreal Thank you. 😀

Ac infinity monitor and controller setup 👌. I’m only running it on a 2×4 flowering tent. Keeping everything sealed up and only exhausting the tent when humidity levels creep up, to keep me in the right vpd range. A 20 gal tank will last me a little over 2 months and my local hydro store only charges $12 for a tank refill or swap. Your plants can handle the higher temps with higher co2 levels and more light. Driving that dragster 👍

[frogslayer]

So, you add CO2 to increase yield but are space limited to a 2×4 tent. What kind of yields are you producing with this “dragster” just curious. It sounds easy and really cheap to run the way you have it set up. I have a 4×4 and already produce so much smoke for my friends and family and I that even if I worked at a CO2 distributor and got it for free I might not even do it.

Basically I guess. First couple grows I tried indoors just came out super airy fluffy, spaced out trichs, clones of same stuff I would run in my backyard. Tried turning up my light and would end up burning the plants. Eventually invested in a pulse pro for the light meter and noticed the co2 monitor would go down to 200 ppm sometime lower. Burning plants under hlg 300l r spec at only 600 ppfd. So after adding co2 I instantly noticed how fast the plants would grow in their first 2 weeks after putting them in the flower tent but still on a veg light cycle to fill out the tent. I’d match the light ppfd to the co2 ppms and every week keep dialing it up, starting at 400 and by mid flower running 1000 ppfd and usually would add a bit mor co2 by this time 12-1400 ppm. The buds fatten up way better then before and packed with trichs. I have 4 tents in a framed insulated, drywalled sealed 14×14 shed on my property and that’s why my co2 levels would drop so drastically before, I didn’t have any intake fans or vents I sealed everything up to control the room with a through wall 230v ac and a basement dehumidifier, keeping the room at 70°f and 35rh. I’ve only been doing this indoors for 2 years now, I’m definitely not the best at it and I’m sure I can improve somewhere. That’s why this place is awesome we’re always learning. Oh yes and on average I’m getting 1 lb or just under from 2 plants each harvest. Thanks
