You might not need to re-dose but a few runs will tell you. If you do though, just add the amount you did initially.

Would it just be a case of keeping an eye on the PH then if it started going down for any length of time add some more CH at full 5ppm dose?
I have been running beneficials and my roots were white for the first time this run, but have never ever been able to keep a steady or upward movement of PH, it is always on the drop. I fear the rot is always there just waiting to return (it did come back on a few in the veg system)

Well if your roots are looking good, dropping PH is a sign your nute solution is too strong or in rare cases too weak. So look at your plants, and go from there.

My Canadian bros, what are you using for sterile res and where are you buying it?
The only thing we have around here is the store stocked 3% h2o2....no luck finding pool shock at all or 35% h2o2.
Any suggestions on what or where to buy? im on the east coast if that helps.

You can’t find pool shock? Where are you, Northern Labrador lol. If you can find pure bleach without added scent that should work. I use chilled water so never add anything to sterilize but I do have 5 gallons of 35% H2O2 that I get from a buddy who runs a water filter company. Maybe talk to someone in the business but it’s almost like buying a nuclear bomb now

Not northern Labrador, but i can almost see it from here
Ya man, getting this stuff online and shipped to me has been near impossible. Not having much success at all finding pool shock. lots of 3% h2o2 but its been said to not use that stuff because of the added chemicals

Tough one. I was able to go without anything in the winter because I could keep res chilled easily but warmer weather was an issue until I built a chiller. I actually quit growing indoors a couple of years ago but may resurrect the lab in the new year. Well if you have no access to a pool supply store or a Canadian tire I’m at a losshahaha

. I also use a pretty robust waterfall type setup so lots of DO.

This is for an aeroponics setup, so DO shouldnt be an issue, or i would hope not lolTough one.

If it’s a true high pressure system then no. I’ve had my worse rot using sprayers though
. The root chamber can get extremely warm due to lights and no water covering the roots, it can lead to rot very quickly in some cases.
