Ok -- I'm a personal-use/medical-type who likes lo-to-no-tech solutions to most of my problems. Reading up on some of these advanced techniques though makes me want to try some real science on my plants. One experiment i want to try is this co2 enrichment. I've finally found a place that will sell me some, and I have in-hand a 20# bottle. Now what?

I've read in this forum where people try to raise levels to about 1500ppm - 2000ppm (corrections to these levels are welcome, folks!). Is there some sort of regulator out there with a solenoid, perhaps, that senses when the level hits a given saturation and shuts off? How about one that senses both the level and the amount of time it's been on? Do I just let the stuff leak out a hose and guess?

All input welcome!
