Dry ice for co2???

Show do you use the dry ice in your grow box ??And its in my room is that ok to breath in all night?? And what are the Benefits of Dry ice ? Heeeelp

Ive just recently started setting dry ice next to the plant (NOT TOUCHING) but so plant sucks up the C02 it puts off. MY PLANT JUST HERMIED. Dont know if THAT is the reason but...theres that.
The purpose: Ive read the plant needs/uses C02 for bud production. (photosynthesis and shit).
Ive also read that the plant does NOT need it when the lights are out.

*dont know how EXACT this info is. Just what ive read.
hope it helps

Yes using Dry Ice wil release CO2 but doing so gives you a unbalanced level of carbon dioxide which can kill you plants.

WELL FUCK! Never heard THAT when I posted this same question. lol
I remember a post on here that listed different methods of C02 delivery and dry ice was 1.
Aw well.. chalk this 1 up. At least I got some nice looking buds this time.

Co2 artificial generation is not feasible in indoor grows for several reasons. Reason number one the stomata of a marijuana plant needs to reach 80-90 degrees farenheit for it to be readily absorbed. If you are running a intake exhaust which you should in indoor growing, what you are trying to create gets sucked out before the plant can utilize it. Reason number two you need co2 monitor gets really pricy and if your levels are too high you can cause burn to your foliage mimicking what ozone burns look like on leaves. Reason number three Co2 implementation is for vegetation it just makes your vegging plants veg faster..most tend to use cO2 thinking you will get bigger buds misconception. Reason number four the time put in whatever method you choose to create co2 is too laborious and the downsides outweighs the benefits. It is best just to have an intake/exhaust free flowing system which you should already have you to obtain consitent amounts of co2 that will benefit your plant rather than having spike amounts go in your grow where it could possibly be detrimental to your plants.

I've played around with a home-made CO2 generator and am convinced it increases yield by 10-15 %.
Note -- CO2 is heavier than air. Means it is a good idea to hang the generator on a hook near the ceiling.
I tweaked my ceiling fan so it disperses the CO2 over the entire grow.

Good luck, BigSteve.

Good advise on the wieght of co2, a buddy of mine has his the same way. I'm guessing you have nice foliage throughout which inturn allows the plant to produce bigger buds.

Knowing the relative weight of things CAN be important.

I was working with animals at UCLA as a lab tech where we used carbon dioxide gas to euthanize small rodents.
One day we ran out of gas so I went downstairs to get some slabs of dry ice, frozen CO2. I was standing in the
elevator when the sucker stopped. There I stood, dry ice in hand, looking around the 6 x 6 foot freight elevator.
I was going to use the dry ice to put in a bucket with some mice. Snap the top on and the mice would be gone in 30 seconds.
Keerist! I was trapped in a small room with frozen dry ice turning into lethal CO2 gas. Then I remembered the gas was heavier
than air and just set the dry ice container on the floor. Saved this rodent!
