co2 boost buckets and bags?

so i finish my first grow, i want to improve things of course, and fix the things i did wrong
ive been at ebay looking at these co2 boost buckets and boost bags, using mycilial mass to converts oxygen into co2
i made a post the other day about nutrients to use and said what i wanna do to my setup yada-yada, and someone said that boost buckets dont really make a difference?
i have a proper intake and exhaust, as he said would be of more value than the buckets. but i feel in my 5x5x6.5 tent that a co2 boost would be beneficial as i grow 9 plants in there cause im sure they use quite a bit
on the info for these they describe 4x4 space for bags and a bit bigger for the buckets, so i figured that would be great for my setup, as the compressed co2 is a bit expensive, but i dont wanna waist my money on stuff that dont work
any info would be much appreciated thanks guys

The bags cost more over the long run than a tank set up. To benefit you need a sealed room and temps of 83.
If you want to piss money away, go for it.

if you don't seal the room and use a monitor to control the ppm's the whole time, as stated above, your wasting your money. do it right or don't do it at all.
in a tent, he was correct, a good intake and exhaust will be what you want to have a constant supply of fresh c02

Just start makin the shine! get a 5 gallon bucket or blue water cooler bottle fill it up with 3-4 gallons or warm-hot water from the tap

Add 12-19 lbs of white sugar. A packet of alcotec 48 turbo yeast (or any high alcohol resistant turbo yeast)

Then make a hole in the top and run a piece of regular air pump tubing into the top of a water bottle with water in it (creating an air lock)

poke some holes in the water bottel around the cap so the co2 can escape.

leave for 5 days.

distill and enjoy.

a hobby you can use to benefit both your plants and yourself.

it only costs about $10 per run and you get about 1/2 of a gallon to a full gallon depending on final abv% and type/quality of still used.

may be a bit late, but i just got a co2ppm meter today (along with my tank equipment!)... for kicks, i decided to see what the co2 boost bucket i've been using can do... i've had the window open to make sure temps stay good. with the co2 boost bucket going and window open, the ppms were at just below 750. I closed the window and doors to the room. 2 hours later it's now at 1155ppm, 30 min ago it was just under 1000. this is in a 15x15 (roughly) room that is not airtight sealed with a pretty large closet open and an attached bathroom door closed but not sealed... so not bad at all! i figure it'll save me on some tank co2 until it runs out if nothing else. Maybe I'll hook'em both up to the controller

1155ppm's wow, wouldnt of guessed that!
