Newbie CO2 question

#435134 - 10/24/01 11:02 AM (25 years, 27 days ago)

Okay, guys & gals... I'm as green to growing (no pun intended) as I am to posting, as I am to digital cameras, so please bear with me...

So, I have brf cakes, 10 gal tank, H2O2+water perlite, yadda yadda... as such:

The question I have is directed more to people using grow chambers such as this (i.e. glass or other material which one can't/won't cut exhaust holes into). I work, and I stay out of town alot... so I've been pondering a relatively inexpensive air exchange... Yesterday I picked up a $8 aquarium pump, sealed a piece of tube just into the cover at one corner. At the opposite corner I ran a piece of tube to the top edge of the perlite in the bottom of the chamber. I need to note here that the chamber is still air tight. When I turn the pump on, this second tube basically vacuums the bottom layer of gasses out slowly. I ran this for hours with my humidity remaining a constant 98%.

Okay okay, now the question: Would you feel this is keeping enough fresh air to the cakes (i.e. sucking all the CO2 out as it is produced?) Shouldn't this be fairly solid state... capable of leaving unattended for days at a time? Has anyone else had success with this?

Thanks for reading!

Drill bits for glass are sold at most hardware stores. I drilled 1/4 inch holes just above the perlite layer.
