I get 100% off most strains.
how long does a 1 gal container of this blend last?
1 gram calcium hypochlorite in tap water in a capped gallon jug. Is it based on exposure to air and the duration of the container being open?
Anyone know the science behind it?
Great idea. and great thread. I used to be on the edge of the tap water system, so had a bunch of friends on well water. They called me "The clone King." I had no idea why.
Moved to a place on a well. Been having a problem with cloning ever since.
Don't have shock laying around. Took out my Clorox (8%). Read the clorox website. trying 1/2 teaspoon (tsp) to 5 gallons. This is the recommended dosage for disinfecting water for drinking. Let stand 30 minutes for residence time. I can always increase the dosage. Will post findings when I have more info.
At the above rate, 1 gallon of 8% clorox would treat 6500 gallons of water.
Thanks
PS. On lighting: I found that T5's and T8's were too light intense. Had better results when I went back to good old T12's.
I got an orp meter because I was trying to get a repeatable process.... All the studies claim 780mv at 6ph (should be .5 ppm free chlorine) is all that's needed to not get pythium.
It obviously is true. Im confident I could have temps go as high as you want them and you'd never get soggy stems. Unfortunately non soggy stems without root bumps are useless to me.
Apparently the 780 mc reading is too strong for the little roots to form or continue growing. I took a clone that just started rooting in a cup of coco, has 2-5 mm roots, thick...white...gorgeous, and put it in the cloner with 780mv reading and all progress halted and the thick white roots started browning and what looked to be getting ate away...burned off etc.
The ppm of the water was 150, that's tap plus bleach to reach .5 ppm chlorone.
I decided to use physan 20 instead of keeping a 780mv orp reading. I emailed the producers of physan 20, told them how I was using it, they said 5ml per 15 gallons for use in a recirculating res. After 9 days no improvement.
Now im back to the orp Meter keeping it around 400-ish. This is roughly what I found when using the exact directions from the clear rez bottle. At 780 it smells STRONGLY of bleach when you open the rez, nose burning strong. At 400 you dont really smell it...
Im really starting to hate this machine. It worked so well the first 3 runs then took a dump. I built a new manifold and all new misters 3 days ago... Close to giving up
I disagree with that statement. ORP is the more precise device, as it states the cleaning power of the water without being swayed by ph.
Quick question...
When testing for chlorine, my strips show total & free chlorine.
Are these values addative or am I only concerned with one of those values?
ORP is notoriously difficult to measure reliably.
its usefull in that its a easy measurement to make in a given online process( as opposed to 5 min intervals with reagent titrators)... but it is infact effected by PH and temperature hence you often see 2,000 dollar ORP sensor packages that include a thermistor and a PH electrode.
there is a reason that they still use reagent based free chlorine auto titrator analyzers for disinfection monitoring in waste water treatment.
