1. It's calcium based. Giving your plants atleast some form of nutrients they can use too.
20 ml per gallon? Seems quite a lot, anyone else used as much as this with good results? My res is a total of 12 gallon which would mean putting 240ml per week? Surely at that strength it'd be toxic to plants?
My bleach is Calcium hypochlorite, at least that's what the bottle say's. So it seems it's the same as pool shock
.
It's like 1-2 ppms at the absolute most.
The powder is 52-71% depending on brand. And is like $13 for a kilo. So for 13 bucks you can treat 198,000 gallons of water. (3960/20=198, 1 gram per gallon, 1000 gram package. 198x1000=198000)My bleach is Calcium hypochlorite, at least that's what the bottle say's. So it seems it's the same as pool shock
1 gram per gallon give you roughly 250 ppms. (Starting water RO) you then use that as a concentrate as 20 ml per gallon. That 20 mls is roughly 0.5% of that gallon. So then you take the 250ppm concentrate and multiply it by .005 giving 1.25 ppms.
So it's the same thing, just cheaper? ?? Well my bleach cost $3 for 3L and I use 15ml at the most and 3 -5ml for maintenance so thats pretty cheap as well at 1000 treatments. But hey I guess it is cheaper lol. Like I said I have both, might just stick with the premixed stuff lol.
I love wash machine parts.
All that information was sourced from my time working at commercial lettuce greenhouse. We ran those exact numbers to keep things sterile. It's crazy the cost cutting steps they take in commercial food production without a single loss of production. Our community could learn a lot from their methods.
Anyone?
You measure the amount of bleach by PH readings? How much bleach is needed to raise say 20 gallons .5?If you only have a ph meter you can ph down a half point lower than bring the water up the half point with the bleach, then check the numbers in this thread and compare. I scale every thing with a good set of digital scales. I've never used a ppm meter and I'm interested in giving everyone a more accurate info with the ph kit calibrated with a ph formula
I don't feel I need other equipment because even if I'm starting in a new location I start the fert level out in the res at 1/6 as recommended for outside use. Until the last decade even horticulturist didn't realize that altitute and climate play an important factor in fertilizer dissipitation. This is why there is not a one size fits all. Then I fine tune it incrementally until the plants come out right. When the res is swapped out and everything is fine it all goes to the green room and used once then disgarded. Proven res water is better for the moms and clones. Better to lose a few budders than lose the whole shit show
Good luck
. Even though it's pricey I have had great luck with saving the plants with hydroguard, hopefully you can get temps down.
