i heard you can use dry ice for co2. is this true
 
Yes you can. You can also use yeast or beer.
 
Go over to OG and look it up in the grow-faq`s, its under CO2, I think. Anything that ferments can be used - I learned a lot over there about it. :)
 
you can also get co2 from burned natural gas
 
YW. There are lots of ways to obtain it. Gas heaters & stoves, yes...
 
but be very carefull with it, you must be sure that your room is totally sealed off, except when it's outside, otherwise you could be ending up dead by Co2-poisoning.
