Do u want be organic or do what to murder them? The 2 spotted mite at 90degrees will produce around 30,000 babies every 3 days. Some types of mites can produce 300,000 very 3 days. So here is the science of spraying. Mites are a 3 stage insect egg, larvae, adult. Most things that kill...

MERIT 75 ,Marathon, Benefit, Mallet all the same thing

Neem oil is not what you what. Horticulture oils are hard to use if you dont know what you are doing. They cause phytotoxicity very easy. Azadiractine is the active ingredient in Neem oil. It is a very affective IGR against Trips and foliage aphids. So just buy the active ingredient there...

That is not for aphids or gnats. That is a foliage fungicide that won't do crap. For aphid control look for a systemic. That means it moves down thru the plant. For good fungus gnat control you need nematodes or spinosad. Go to Monterey Garden products if you want OMRI.

What are you using as your media , a mix pure peat ( rice hulls) ? I dont know what Exict R is but if i were you i would go with a base fert. cal/mag . I would get a water test. The tap water is what is driving down the PH. Most mixes start at around 5.5 and with 80% of the water out there...

Solex is a waste of energy and time. 2 layer poly is the only way to go. I like AT over berry, or klerks but which ever you use always get the thermo with anti-condensate and Solar Ice. Saves 20 to 30 % on heating and cools in the summer. Also you get better light diffusion ( NO shadows)...

these are a couple of pictures of my greenhouses. as i am getting ready for spring again. And as for the Poly a only use AT thermo Max and SolarX. you can get Shade coverings in any color that only block 25 % which help to cool the houses.

I will bet 100 to 1 that you are using dirt, Not peat moss media. Then you mixed in some mulch, and in your infinite wisdom you have been fert. with a netural Ph fert. If you check the ph of your water it is above 7.5. So what this means is you are using dirt from outside with a hard wood...

Avid works on just about everything.

That is caused by an insect. If you are growing inside its a mite or trip. Outside it is a mite aphid or gnat. Something is sucking your plants dry.

Oscar has got it right. You have to rotate and hit with different MOA's. Ever 4 days is best with and mites or thrips. They will make 300k ever 3 days at 94 degrees. The best drenches are Marathon, Kontos, Pylon (if it is all out war). Pylon is not for the faint of heart. at 400 $ a...

Kontos has a veg. label Judo does not. I don't even think you can purchase Judo in CA.

Hi I am a large greenhouse production owner. With the new CO laws i am growing on a trial size. I have 30 years in the greenhouse. I own a 2.4 acre greenhouse production facility. I do seed, Clones, and tissue culture. Have flood floors, ebb and flow as well as bench growing. I use peat...

Is anyone doing Tissue culture, or is seed and cloning the only production.

I think that everyone should look into Kontos. It has a veg. label and is systemic with a 6 to 8 weeks. Its sister product JUDO is the number one mite control in the Greenhouse industry. You can water in as a drench. I have just started in the Cannabis growing but i have 30 years in the...
