  • I picked up a sack of GNATROL and neematoads last Thursday. The young man explained how to use both but I've totally forgotten. I'm running 12 dutch passion xxl Autoflower strains in this awesome grow soil. I got a serious gnat and some other tiny flying insect I need to get rid off. Seems since the cold weather set in the bugs have got worse. Also I need some red worms do you have any instock? My 1st run in red bud soil there were no alive red worms I used Canadian night crawlers from a local bait house. My plants also have the cover crop of buckwheat and clovers.

    Use the gnatrol at 1 tablespoon per gallon of water soil drenched once per week. The nematodes can be mixed into a 5 gallon bucket of water, mixed over a period of 30 minutes, and then strain off the vermiculite. Here's a video going over how to do that Right now worms in the store are going as fast as we get them. The best thing to do is call on a wednesday to check stock.

A must in your IPM

Product is easy to use and extremely effective. 1 table spoon of gnatrol per gallon of water once a week and you won’t have any problems.
