Do homemade co2 generators work?

Is co2 worth it?

That's 2 different questions. 1.Absolutely they work if your talking about the yeast diy ones.
2. That's very much depends on your lighting and if you have a sealed room.

if your thinking about it in a tent... It's a waste of time.

Oh yeah why so I've just got two plants and dont think they'll quite have filled the required space in the next 6 weeks and thats the longest i can leave them in vege so what would be the best way to speed up the vege cycle and fill the space?

No good in a tent because of the ventilation fans and you can't stop using them or humidity and heat will be an issue.

All you can do is try to optimize your conditions and provide the most light you can. Switching to 24/0 light may help if you are lacking on the light.

Can't really give more specific information without all the details of your grow.

Im running 2x600w hps bulbs one per plant its on 24hr already so i can keep my heat more regulated was going to do 4 but the two grew a lot bigger by the time the clones rooted so i just stuck with two. Im in a tent 2.2m high 2.4m long and 2m wide

All I can suggest then is VPD to maximize growth. With CO2 you would need to seal the tent add AC and dehumidifier in a small space you would definitely need controllers.

Whats VPD stand for?

Whats VPD stand for?

Vapor pressure deficit. Let me see if i can up load this spread sheet for you. I was doing this to pass info easily on the forum since this and lighting come up a lot.

Nope no won't let me. lemmie copy paste

Veg 0.8-1.1 Early flower 1-1.4 Late flower 1.3-1.5
Clones and seedlings: 5,000–7,000 lux
Vegetative growth: 15,000–50,000 lux
Flowering: 45,000–65,000 lux
Maximum recommended amount of light: 75,000 lux
Please do some research VPD in general to help understand how other factors can
affect success and failure. Eg. Airflow can be the difference between getting mold

Use the info in the very last link to make your own calculator in excel

Its a lot of reading but its important to understand. The big part is the calucator. You can just punch in you number and bam you have the settings you need to achieve that VPD. I listed ideal VPD for stage of growth at the top.

Any questions just let me know

Thanks much appreciated

Increase light intenty to nearly flower levels and minimize stress. Otherwise, not much you can do to speed up a plants growth rate mid veg. Keep in mind theyll likely double In size after you flip, so you ready only want them to fill the room to 75-80% full anyway.

Thanks much appreciated

You will need and infrared temp gun to use this. You can get em for about $15 on Amazon. Leaf temps are very important in the calculation. If not you gonna get the wrong info out of it and your humidity will be to high.

Thanks yeah the strain im growing is green crack first time growing it apparently it gets quite tall so hopefully will be able to bring some of the stretch horizontally to fill the space
