thanks a lot, I will search for a welding supply store this weekend then and get one. I figure if i am gonna grow then i better do it right and not cutt any corners
how long does a tank last on avg? and wondering if you can put it on a timer to collaberate with your room exaust? b/c I dont see the point in pumping in fresh air and CO2 just to exaust it right out.
I'm in the middles of adding it to my flowering room.
In the veg room, I just have a paintball can of CO2 giving 3 shots an hour nothing calibrated in the least. The co2 won't fire if the vent fans are on.
In the bloom room, I will have a CO2 meter with feedback to my controller. The controller is a PLC and runs the whole show (lights, water, CO2, fans, etc)
I'm hoping to get the bloomroom set up with the CO2 tis weekend. (its on the other side of the house, so gotta run cabling or use another PLC)
You may find the welding supply shops to be closed on the weekends or only till noon on sat.
As far as how long it lasts, there is a CO2 calculator in a sticky, I *think* in the room design forum.
