Granulated PH up/down ???

[BILL THICK]

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:

BILL THICK Reviewed by BILL THICK on 10-24-2005. Granulated PH up/down ??? Can anyone tell me if you can use swimming pool PH up/down in granulated form to adjust the waters PH level for watering your plants? If so are there any precautionary hints that should be taken into consideration?? Zandor, my friend, if you happen to read this , do you run any sort of ebb and flow along with your drip watering system or is it entirely reliant on your drippers for your normal watering periods?? Peace Bill :D Rating: 5

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.
