Co 2 bags ?????

[G']

Hi guys been reading some conflicting info regarding the Co 2 exhale bags, are they really necessary for growing canna if you have a good extraction unit along with a good intake unit ???? cheers talkers, G'.

What I've read is that they actually let off such a little Co2, it's not worth the effort. The pros will confirm though, G' my man

Waste of money mate, O2 supplementation is only really useful in a closed environment due to the contact time required and those bags will never produce the ppm's that are needed anyway....

Cheers boys you've just saved me a few quid, G'.

Plus the fact that the amount of CO2 given off is instantly sucked away by the extraction

That is a VERY good point Kind of makes them seem utterly useless

if you want extra co2, pump in some fresh air,
that'll give em more than enough and it's totally free,
