If you were using it as directed, and if you believed the half life was true... E20 would not keep PM off of your flowers past week 4 or 5 (which is when PM shows up a lot of the time), if you got spores introduced to your room again (very easy since spores can remain in the room for a long time). I fought PM for 5 months before I used E20 on clones and on the veg plants. I also scrubbed my whole room (did a complete teardown and bleached everything). I have not used e20 since, and I have been lucky enough not to get PM. I do use my bennies, which have species which systemically fight PM, and are 100% safe to handle.
Yes when used often PM can develop a resistance to E20. Biological species are VERY capable of adapting quickly in order to infect hosts in order to survive on Earth.
Again, E20 will not cure or prevent bud rot, which is due to too much humidity, not enough air circulation, and/or dense flowers..You woudl be getting budrot at weeks 6--> anyway, so E20 would not be effective no matter what (if you believed the half life)
E20 as a last resort, and never on flowering plants. Keep in mind that there are no studies that will ever be done on the toxicities of E20 when it comes to edible flowers. Better safe than sorry.
Bud dog mutt, you need to relax bro. You don't need to post 3 times in a row to get your point across. You are entitled to do whatever you want in your garden, provided you are using all of what you grow. The problem is when you make a short post only saying how great
eagle 20 is to use on all of your clones etc.. people may get the wrong idea and think that it is safe to apply.
I am pretty sure that E20 is not even legal in California FWIW.
