0.1g.
i dont mind mixing up a bigger batch then using a a few grams of that per gallon of water in res res. how long would this stuff stay good if i mix up a big jug of it

i always measured mine out per res change. there is a thread here called make your own Clear Rez. do a search for that.

Ok here is the quick and dirty version: first, its important to understand that 1 ppm = 1 mg/L. The basic operation is to multiply your water volume (in liters) by your target ppm (i recommend 5-7ppm) However, your pool shock is 70% free chlorine so every gram you add is short 30% and to be accurate you have to account for that. If your target is 5ppm, you have to multiply 5 by 1.3 (this should come out to be 6.5). Now multiply that by your water volume in liters. Divide the answer by 1000 and that is the shock dosage in grams for your specific volume of h2o in order to achieve 5 ppm free chlorine. You should be good if you are accurate to 0.1g, my numbers come out to 0.86g so i do 0.9g for my 35 gallon system. At rez change i dissolve that amount of shock in a cup of hot water and dump it in after my nutes are in but before i do my final pH. I recommend letting it sit and dissolve for 5-10 min before adding it.

i read on a post that i should mix up 20grms to 1 gallon water then use 1mil of that per gallon of water in my res. it sounds like allot to me but i guess ill just have to experiment and start with a low amount

That's not right I don't believe...It's more like 2 grams per gallon, then 3-4 ml per gallon of that solution

Here you go.

Make $2200 worth of "Clear Rez" for $4 !!!

That is correct. Same EXACT ingredient as EZ Clone Clear Rez that sells for $20 a QT. Get your self a 1 lb bag of HTH Pool shock non PH buffered available online and most hardware stores (bought mine from Ace). Mix 1 GRAM (450 in the bag) per gallon of solution. Will make the SAME EXACT...

If the OP sticks to this recipe
you only need half a teaspoon of solution per ten gallons
This I know because I made a jug years ago and it is still nearly full :weed:

if you are using HTH pool shock, i think your numbers are off. you are slightly more than 3ppm free chlorine with 0.9 in 35gal
and up to 5ppm is safe for plants. 7 is too much.
and his mix is 70% calcium hypochlorite, not free chlorine. HTH is 62% if my memory is right.

i dont have a root problem but i want to use something to keep it that way. i don't see my self needing to use big amounts of this stuff. i will probably only run it every second week for a day before a res change unless i see problems. if my ppm and % are off im hopping ill be fine if its not im my res all the time

The brand I am using is 73% calcium hypochlorite. (70%free chlorine), same as the op.
I am basically around 0.02-0.03g per gallon to get 5ppm. I do it the way i described because its just way easier and i have the piece if mind of knowing the real concentration of free chlorine in my rez. The math gets more complex when you are making a solution and dosing your rez with it.

People run it in their cloners too, for trouble free cloning...I've been experimenting with this...and have roots! Nothing but water and this solution!!

My scale is accurate to 0.01g so the dose i use comes out to 0.86g for the whole 35 gal rez. When you do the math you can go out as many decimals as you want; I like to go out 4, but of course understand it has to be rounded to my scale's resolution when i weight it up. The op said his was 0.1g so i just meant if mine was only accurate to 0.1 i would just round up to 0.9g.

i use a 0.01 scale too. i wouldn't use any less.

The product he is using is likely 73% calcium hypochlorite which is 70% free chlorine. If it is 70% calcium hypochlorite the free chlorine would be lower; he would need to read the label to see what the free chlorine was for that product and use that in the calculation instead of 70%.
