I just ordered Nematodes yesterday from Amazon. I paid for overnight but 5 days is what its ended up being. Fkg Amazon. I researched and it appears that they should be viable. I have a real microscope to check. Theyre flying around here already so i wanna clobber em before they do any harm. Apparantly, Amazon doesnt sell gnatrol in less than a 5 gallon container at aalmost $600. I will keep everyone here updated on their effectiveness. My wife has houseplants suffering even if i havent had more in my weed. I think its cool how they work.
How did your nematodes workout?
Nice one mate, I'm glad you got them beaten, your determination paid off in the end.
Sorry for the delay. Ive been waiting to see long term results. I believe that the nematodes work. For a few weeks i saw none. Then this week, ive seen a couple in the growroom, but the plants are doing well enough. The big 1 is 2ish weeks from harvest and although i burned the tops, the bottoms are very healthy. The smaller plants are finally big enough to start bottom watering. The only issue i see using the nematodes is them running out of food and dying off. I bet that outside plants would really benefit as there would be new larval gnats every so often to keep the nematodes from dying off. So, yes they work but there are so many gnats around here that reapplication once a month would be necessary and they only stay viable for a month in the fridge. I will probably buy some gnatrol for next time but these do work. Theyre just a little too efficient and dont last long enough when food runs out.
You are aware that diamataceous earth does not work when wet?
I figured it was an application method. Apply in the water, pour in the potting mix when a watering is due, then there's some of it distributed throughout the mix. Some of it must stay in the pot!
It's not that it doesn't stay in the pot. DE loses it's abrasiveness, when wet, which is what makes it effective.
Just don't water the container for a few days after adding the DE.
I have a large box fan set on high. The plants get a little wind beat and I havent had PM or Botrytis in several years. The gnats..... these fkrs here will crawl in and up the container holding on for life till they get on the soil. Yes, its rough flying, but they have nothing but time. Ive found that Pantyhose over the bottom holes and bottom watering is the best way ive tried. Spraying H202 solution on the topsoil once a week( thanks to @Budzbuddha for that tip) seems to keep them from doing much damage. Im going to pay up and buy some Gnatrol.
