Granulated PH up/down ???

Hey Zandor .... great info , thanks.

Just saw your SOG project totally awesome. seems I get to one method you have showed me and you come up with a better or another good one that leaves me wanting to try it!!! lol Plenty to learn and keep me busy in my old age. All kidding aside I have learned a great deal, it's absorbing it all and putting it to proper use that takes awhile. That sog is great and I will be having to try something like that in the near future. In the meantime I can adapt my drip system into a more efficient method using what you have shown me here.

The CO2 regulator, I have a brand new still in the box acetlyne welding regulator and the works, would I be able to make them work for CO2? Co2 can be dangerous if the room has any leaks aye??

Thanks again for all your help and I personally find your experience and knowledge a total asset as I'm sure many do
Peace :stoned: :D

Thanks Bill I hope you and your brother are doing better these days.

CO² uses an oxygen regulator from what I know but I don't think the regulator knows any better. You do need the electric valve to turn the gas flow on and off. The only dangerous part of using CO² is when the level rises above 1000 ppm for extended periods of time. You really want to get it up to 1500-1800 ppm and hold it there for hours at a time. That is the dangerous part you can't enter the room while you are using CO². It can make you pass out and kill you but it does take well over 2500 ppm to do that. I just don't take any chances so 30 min after the lights go on I start the CO².

Now here is where others freak out.

I do my work during the dark period under 25w green bulbs (plants donâ??t see the color green) so it safe to enter and not waist the CO² the plants need. You do need to exhaust the CO² from the room once the lights are out plants canâ??t process the CO² during the dark period or if you have then under fluorescent lights.
