Best way to sterilize coco coir?

[PadawanWarrior]

I use a home made bubble cloner, and just add some shock to the water.

Do you measure how much you add?

I make a stock solution of 1 gram to a gallon of water, then use that stock solution at a rate of 5ml/gal in the bubbler every 5 days or so.

The stuff I would use would be Calcium Hypochlorite. That's what most people use for plants. I've used a bunch of different shit in my hot tub.

So Pool Shock is not Calcium Hypochlorite and only 65% pure? Never found any precipitations with bleach but a lot when making Pool Shock stock solution. Both works for their intended use but saying Pool Shock is better at the application concentration 3-5ppm is false.

Are you seriously arguing with me about different chlorines? . You obviously have no clue about the differences.

If you read my comment again I said they both work for their intended use, that's not arguing is it?

What is the advantage of using poolshock instead bleach to sterilize? Seems like you would want to rinse and buffer the coco afterwards either way, and poolshock is pricey in comparison to bleach. Does the small amount of calcium aid in buffering significantly?

I've never had any issue with precipitations making a stock solution of pool shock, in fact it's crystal clear.

poolshock is pricey in comparison to bleach.

A small bag of pool shock is like $5 and will make hundreds of gallons of stock solution. By comparison, bleach is around $3 a gallon. So, bleach is pretty pricey in comparison to pool shock.

None of them are really pricy. And yes if you have a good clean source of calcium hypochlorite it's marginally better. The difference is so minute at the low dosage of only 1-5ppm.

I already had the Calcium Hypochlorite so I mixed up the stock solution. Do you add any nutrients, or just plain chlorinated water?

Just water. I keep the surface of the water at least an inch below the bottom of the stems, and let the effervescence from the bubbles hydrate the cuts.

Diluted the stock and made a quick bubble cloner with a wine bottle that was sitting here. Thanks PJ. This will be a fun experiment.

I've switched over to "making" my own bleach from pool shock too, I'm always happy when I can stop buying more bottles of liquid of any type.

Thanks. You know the percentage of chlorine in the bleach? I use pool shock with 68% chlorine but can do the math on liquid bleach. I'm also thinking about starting seeds in rockwool cubes rather than peat pellets. Does rockwool dry out quick enough to not get damp off? I think that's part of the problem with my coco it's not drying out quick enough.

Are they the little jiffy pellets? I too had quite a bit of trouble with those and damping off. Moved over to just start using little cups of loose coco or a solo half full and didn't have any further issues.
