I've done some research myself and most of the information I've found is positive but I have heard alot of negative opinions on it too. I have no personal experience with them so in interested on what people say or what your experience will be. I suppose the only real way to test them would to run a system without the bag, and take co2 ppms then add the exhale bag and retest co2 ppms to see how much it raised. I believe the optimal ppms is between 1000-1200
yea seems like you are going to need high light levels as well as high heat before they actually work from what I've read. I don't have a co2 meter (nor do I plan on getting one) so I'll just have to eyeball it. I'm going to toss in all 3 bags into a small grow space and see for myself in a couple months. I don't really know of anyone who uses them or has used them. Would be a super cheap alternative if they actually work though
Somebody around here tested them with a meter. I recall he stated the increase is marginal while it's also wasted over night. From what I've read people need to know and maintain the higher co2 ppm range so they can raise temps to the required level to use the co2, being why they use a meter, sealed room and timed/calculated co2 release.
Very interesting and something to consider..much appreciated
You have to understand that one of the reasons there is so much mixed reviews on them is your growing ANOTHER organism, another species in along with your plants. Mycelium needs a rather specific environment to survive, and if every person using exhale bags treats their environments differently, their going to get very different and inconsistent results. I can only imagine those bags being good for smaller environments, but I'm also not 100%....I can't bring myself to spend the money to do the experiment.
Yea all this sounds very logical. Especially being good for smaller environments b/c the only couple vids I've seen with actual co2 meter tests being done showed little ppm (though it did increase) in a small space. I gave in and bought a single bag b/c I just have to know for myself and I'd prob not spend the money on more myself, but I'm being gifted a couple. If I notice within a few months for my small grow are a noticable difference, I'd gladly pay 30 bucks a bag. They supposedly last much longer than stated, up to 6mnths. If I can produce excellent yields from less than a hundred bucks in half a year this will be the only co2 I'll ever buy...and recommend..Guess I'll have to keep everyone posted b/c everyone is in the dark it seems
Ive never heard of a raving review on the bags....and the only way youll be able to do any experiment with one is with a meter...I hate to say that your spidey sense isn't going to be sufficient in determining whether there is enough CO2 coming from the bags lol. I pay $7 every 4 or 5 days or so. So lets say I refill my tank 11 times a harvest (counting cutting it the last 2 weeks) that's $77 for CO2. Granted there is a set up cost but to me that's worth it.
You don't breathe out enough CO2 lol, not even close!
LoL well maybe I'll have to judge co2 levels by how lightheaded I get locking myself in for a couple hours..for what little I grow and for my situation tanks and all that good stuff just aren't a possibility for me..it should turn out an interesting experiment nonetheless and I'll prob just have to get a meter to soothe my curiosity I'm guessing..guess maybe when I do I'll start a journal on here
What does that tell you- I've still got plenty to learn.
Depending where you live, you might be able to find one on craigslist, I would love to see numbers on an exhale bag!
You need to stay rational and emotionally detached or placebo will bite you in the ass. People suffer a lot of expense to seal and pump a room with co2 along with what must be a massive head ache of initially calculating co2/flow rates. A lot less people would do that if a cheaper or easier alternative existed, even if not quite or half as good. If you do get excellent yields it's highly likely you had a good stable environment and were not feeding too strong. That part alone is proven fact as people pull huge weight with no additional co2. If it's the case that your particular setup has a drastically low ambient co2 that is holding back growth then a bag ''may'' contribute to better yields. If you at-least get a co2 meter and fan speed controller you could slow down airflow more to try and increase both heat and co2. The finer details of that you'll have to figure out yourself.
