CO2 questions...

Would it be good to add CO2 to my 5x5 grow tent....or if so are these any good. Says they last 6 months...says they are good for plants in small grow rooms, tents ect...

I'd recommend using at least 2 bags in your 5x5..

In your experience, how many ppm does this increase levels?

Hey my soil pH is 5.4 I got dolomite lime, but it's tiny pebbles...should I crush them up and add to watering????

co2 is a waste of time unless you have got a seald envirament as your fan will just suck it out and blow it down the road

I don't think anyone on forum is running CO2. As @Dell boy said, you need a sealed room, with an airlock.

I believe CO2 bags are just an attempt to grab inexperienced growers money. They aren't going to raise the ppm to 1500.

CO2 is for commercial grow rooms, not for residential. You need your grow skills at demigod level to be able to take advantage of the slight increase it potentially has.

CO2 can allow a higher DLI. Up to about 35 DLI you get roughly a 1% increase in yield for every 1% more light. after that you only get .2% gain for each 1% additional light.

At these high light levels, any error is totally burnt plants. A serious leak can flood a dwelling with CO2, and kill you. Read that part again.

I use the CO2 bags if it helps. I've also experimented with yeast bombs too - homemade bucket w/yeast and sugar. I do not have a sealed room, or a CO2 PPM meter. I cycle my exhaust on and off via a schedule.

Exhale bags recommends if you don't have a sealed room to put the bag on the bottom of your tent to draw up through the plants.

Do they work? Hell I don't know man. I started trying them out on a whim to play around with. Guy on eBay who apparently lives down the road from the Exhale farm and gets them fresh he says. Sells them fairly cheaply. One thing to note - the 365 bags are supposed to last longer but they take about 3-4 weeks once you mix them to start really "working". I use 2 in a 4x4 and 1 in a 2x4.

So do they work? Again, I do not have any way to say yes. Or no. I do know that once I started playing with a homemade yeast bomb, I started getting larger plants. When I added Exhale bags to my grows I started getting my biggest yields yet. Last grow was 3 autos @ 9.9 oz, 13.4 oz and 20.5 oz respectively. You can check out my grow thread linked below in my signature.

Again, I do not know if the bags help or they just sit there laughing at me. Or whether when I added them, it just was at a perfect time when I became a better gardener. If CO2 PPM monitors weren't so pricey I'd like to monitor it, but I don't have one.

For me, it was one of those things that I just added for fun once I had dialed in my grows. So always recommend that first and not expecting a magic bullet. I'm perfectly fine knowing that it could be total snake oil. But I continue buying them because I'm totally superstitious. $30 for a bag that lasts 4-5 months is a cheap way to play around. They do add humidity though. So that's a good thing for me. YMMV.
