Co2 is good in the grow box/environment...yes?

If true, which I read that C02 in crucial for fast plant growth then would it be good to put some dry ice in a bowl in the box/grow area? Wouldn't the melting of the dry ice create a C02 rich environment?

That would destroy the roots

it wont burn the roots if you dont put it on them! my indoor medical growers bible says that is a known method

well the AG FILLS up with roots, there no way of doing it

In the grow box not on the plant....Right? As long as you have adequate lighting so plants can use the CO2................I've heard it's a waste of CO2 with fluorescent lights as they don't have enough juice for plants to use the extra CO2.I only use CO2 for flowering since I use HID lighting................... fluorescent for veg

I had a friend who said the same thing but he said to put it into the rez hh, so thats what i thought he meant

No, not in the rez, just in the closet, like in a bowl. To slowly evaporate. But I guess if I flower with cfls, then it wouldn't help. What about the sugar/bakin soda in water method that is mentioned in the FAQ here on RIU?

sugar yeast and water shake every couple hours
