Here is the situation:
Six plants in six five gallon containers. I (stupidly) used miracle grow potting soil and consequently about a month into my veg grow these fungus gnats started showing up. I ordered Azatrol upon some advice from my local grow shop and it has helped cut down the population but, it just cant seem to get em all gone. I have excellent airflow and only water about every four days at most(sometimes every 5 if soil is damp enough). Plants look great to me and have grown about 1/4 to 1/2 inch every day on average for first 2 months. Temp is 76 to 80.5 "daytime" and never drops below 71 at "night". What can I do to finally knock these things out. Ever tried about an inch of sand(salt free) on top of the soil?
Please pass on your experience and knowledge to me in regard to these flying nightmares.
Just the thought of some larva below the soil snacking on my girls infuriates me.
BTW--- got 4 papaya strain, one critical sensi star, and one caramello. all female happy to say. just started the flowering stage about one week ago.
I gotta give the members of this forum about 90% of the credit on my luck so far. You guys(and gals) are a hell of a resource for a newbie that would be struggling otherwise.
Thanks in advance for your attention to this matter.
