I have successfully used Zerotol that was over 2 years old, but I haven't found its official shelf life. I still have that batch, which will be over 3 years old now and will see how effective it is. Oxidation is the main enemy of this chemical formulation. I'll contact the company and report back when I find out anything. I have had a quart last me for 2 years in the past, as Zerotol 2.0 only requires a table spoon and a half per gallon of water. There is a new Zerotol product that is greatly diluted for home gardening use, but I have no experience with that product.
Give me a link to my next PM spray to try

Being an out door grower in the south, there ain't no getting away from humidity! Zerotol and Oxyphos, another biosafe product, make it possible to get crops to the finish line!

You could use peroxide strips to test the potency. Once it's 25% weaker just use 25% more of the product. Of course that's assuming that the acid loses potency at the same rate.
I don't know if you need a floor heating system.
You could try setting the plants on wooden pallets which will get them off the direct floor. Sometimes pallets can be found for free.
If I was going to build a room in my basement I'd glue some bricks down and glue OSB to them for a floor. 1" foam on top of the OSB floor.

I'm up off the ground on wheels though, and don't have much ceiling height to raise them either. . I really don't wanna rip up my new floors to install electric or liquid coils either. I can't add skirting or do anything permanent looking to keep the air from blowing under the trailer, and never know when it might need to be moved. Plus, i store a bunch of materials underneath it, which constantly need to get at. Maybe I'll just get a spray foam kit, and do the entire underbelly a few more inches. Or add more 1" rigid foam, with yet another protective barrier sheet ofmetal like is already down there. Suppose i could just buy a few of the larger heating mats made for ice melting, and lay them down when needed. Nothing beats radiant floor heating!
Any other plants I had on regular heating mats over the winter didnt get PM , just the one near the cold un-insulated enough floor. Come to think of it, I didn't run my aquarium heater like I normally do either. The water was pretty cold , even sitting next to an oil heater...

Yes inside a tent on the floor in the summer. In the winter I put a piece of cardboard under my rez in DWC.
Whats the difference between this and zerotol 2.0? Can you use zerotol until the end of flower?
ZeroTol® HC
ZeroTol HC has been formulated for use in hemp & cannabis production, as well as for homeowners and hobby growers. This product can be used on hard, non-porous surfaces to eliminate pathogens that linger there; but is can also be applied directly to plants to prevent/treat/control plant...www.arbico-organics.com
This is basically a diluted version of oxidate/sanidate. Comes in a gallon for 43$. I think the rate is usage is .85 oz per gallon.
@nxsov180db which one of the above 3 should I dip my cuttings in after I take them from my mother before I put them in rockwool to root? Also what ration should I use for product to water? My clones have been rooting slower with the PM. @curious2garden
Or is it good enough just to spray the mother plant very good leading up til I take my cuttings?

Its 5.3% peroxide and 1.36% peroxyacetic acid vs 27% peroxide and 2% peroxyacetic acid that zerotol 2.0 contains. So it's slightly weaker with the peroxyacetic acid and a lot weaker with the peroxide, but you use a higher dose, looks like they recommend .85oz/gal.
The regalia you spray weekly so I guess if you were taking clones from the moms and they were about due for a spray you could use regalia as a dip. I would personally just spray them before I take cuttings, a day before or an hour, so that they dry, then use purecrop1 as a dip. If you make a mixture of purecrop1 and water you can leave it for a week before it goes bad, or at least before the company says it'll be no good, so you could keep a half gallon mixed up and re-dip your cuttings every few days. or you could just open the cover of your cloning tray and spray them.
Yes, you can use zerotol right up to harvest and even wash your freshly harvested buds in it.
@nxsov180db
Any reason you told me to do the PureCrop 1 at only 30ML/gallon? I think its more like 60ML a gallon according to the label.

I love purecrop, some of the best stuff I've ever used, been using for 2 years now..
Dosages are simple..
1 oz per gal if its preventive measures, 2 oz per gal if it's a heavy infestation of something, spray everyday for 3 days straight if heavy infested, then once a week after..
You can apply this stuff up to the day of harvest with no ill effects..
Good stuff, hard to find in Canada right now.

1 Tablespoon per gallon of water. Drench spray. All this does is make high PH water. Kills surface PM. Weekly application is what I do outside as PM is a given working in the great outdoors. Household baking soda (Sodium bicarbonate) can be used as well. Same 1 tablespoon per gallon of water.
No smell, no taste, no residue, organic rated.
I don't see how the soy bean oil and the corn oil in Pure Crop wouldn't leave a residue, at least enough that you couldn't use it near harvest?

I've had buddies use it the day before harvest, no ill effect at all, I've used it before up to 5 weeks into flower and I also had no signs of residue or anything.

30ml is what you do as a preventative, 60ml is what you wanna use when you've got issues. I think in another post I mentioned using the 60ml for the clones you just took that came from a mother plant with pm.

That’s nothing but soybean oil and a surfactant. With citric acid as an “inert” ingredient.

Citric acid works perfectly in an IPM mode. And that’s your key, bud. Preventative. Curing it is a bitch.
