bb gun co2

i gotta question that if i just go in my grow room and open one of the bottles and spray it on my plants is that a good idea? i got like 20 of them cans they been flowering for 7 weeks! if i can do it how do i open the bottle w/o burning my hand off? and how far do i keep it from the plant b4 itll kill it?
how many should i use each time? should i use like 1-2 per plant? their like 27 inches! and topped and lstd!

Don't try it man. You really have no idea what your doing.
Just make some homemade co2 like Robert said.
You're getting too late to be beneficial anyway.

k but my strain is from sum stativa bagseed so it might take like 12 weeks!

You would need literally hundreds of those every day. It is not worth the trouble to use those tiny canisters. If you insist on doing CO2 the cheap way, use the yeast method. Otherwise, what you are proposing is a complete and utter waste of time.

Theres no way you would effectivly be able to deliver the proper ammount of c02 to your grow room, using small co2 tanks. You can buy C02 tablets or use a yeast + Sugar solution.
