i'm looking into pest prevention and was reccomended azamax (general hydroponics- mostly neem i believe). my question is i have added the azamax to my resevoir but it says to only use it every 1-2 weeks so should i drain the res after today? after one water? or lets it run its three day course?
I run azamax in my reservoir and usually add it 3 or 4 days before I change the res. Then wait 2 weeks and add it again. It takes a awhile to take effect from the bottom but is definitely effective once it gets there.
