co2 bags?????

i need to know if anybody has used this organic co2 bag called

exhale co2 bags
for growing the ganja?has anybody had success? or is it a sham? anybody who knows about it let me know? i got a 6 x 6 room by 9 ft tall i wanna know if this co2 bag is worth it,im new my first gro room, i got a 600w lamp with drip and hydroton if it helps with a answer on co2 issue.thx

Isnt that just some mushroom compost? From what i understand, it doesnt smell all that great. I personally use CO2 tablets from an aquarium supply store.
