I have grown several times indoors, but thanks to all the help I got on GP, I decided to try outdoor growing (second season outdoors). I am having very good success this year with Sensi Star, and  a local cross of Presidential OG X Blue Dream. My area has had a very bad infestation of swarming flies. From what I have read, they are basically house flies that gather in massive  swarms, then lay there eggs in the moist soil, to come out and swarm again. I must have 1000's of them on my plants, on the wet ground (soil) leaving fly spots all over the leaves and buds. I am about 2 1/2 weeks into bud, and am concerned about the damage to the plants due to fly spots, and flies getting stuck in the buds. I am currently hosing down the plants every week to get the old spots off, but by the next week, they are covered again. Any suggestions would be appreciated. Thanks

Netting possibly, but I've never had anything that bad. You might check with your local ag extension service and see if they have any answers. Just them your growing flowers. :)

I am way past the point of netting i think. I have 30ft x 30ft garden, and a 10 to 14 foot canopy, with nothing to anchor the nets too. I was expecting a 6 to 7 foot canopy at most, but these girls went nutts on me. not that I am complaining too much.

I am not sure what you mean by ag extension service?

You should have a local county extension agent... http://www.ipm.ucdav...ficefinder.html

You might try spraying them with Neem Oil.. It has a wide range of uses, one being eliminating pests in organic farming. Can be purchased in most garden centers.

I'd use a combination of Neem oil with good old fashioned soap.

FYI, I found a great way to knock the number of flies down to maybe 5% of what they were. gorilla tape on the ground, hanging from the bamboo support stakes, and anywhere else I can get it to stay. Regular duct tape works too, but not as good. With the gorilla tape, I bet I was catching 2 to 3 thousand flies in a 24 hour period.

 

Here is a pic of my Presidential Kush X Blue Dream.

This is the first run of these seeds, I did not expect them to be stable, but i am in the fourth week of flower, and no hermies yet. And the color, never expected that. I am showing 3 different phenotypes. One is giant, 10 to 12 feet high, and about 8 feet wide and lots of purple on the hairs. One is about 6 to 7 feet high, and x-mas tree shaped, normal white hairs. the last is giant like the first, but only normal white hairs.

I cant wait for October to come around
