CO2. Is it worth it

[hempheadjack]

Dont be fooled by bullshit people. Read anything ever written about weed and it says CO2 increases yields a shitload. Dont believe this about CO2 bieng a waste.

i read somewhere that co2 wasnt even invented yet for the use of indoor grows,,,we did not have power back in the early days,,so,if i read anything ever about co2,,it will date back to the roman days,,,and weed,,,,(anything),,,,,Jack
