But too much carbon dioxide will kill them. The roots aern't going to be able to get any oxygen if there is none available.

VERY sick plant, too much effort to let die! ok, so i haven't posted in awhile, but my grow was going well and i simply didn't need any advice, nor did i deem myself qualified enough to give any, so i just kinda faded out. but to the problem at hand, my plant. it was only a few weeks into flowering, lights on a timer (12/12) flowering fert, everything. when, in a matter of about 36 hours, my plant took a drastic turn for the worse, and i'm afraid of making things worse and destroying the only plant i've got left and having to start Rating: 5
