I found that the best way to get rid of fung gnats is to fill a 2-3cm layer of brittle sand 😉 so I'll see

Hello Grower 😊 I read that Nimb oil helps with fung gnats. Do you have any experience here, and if so, in what proportion to mix the dressing to kill the larvae in the soil?

The best control for fungus gnats is beneficial nematodes! But if you’re going for the Neem oil route then I’m going to send you over to what helped me! 1 Gallon warm water 1 tablespoon Neem Oil 5ml Agsil16H Liquid Solution 1/2 Ounce Essential Oil Blend (optional) Source: https://buildasoil.com/blogs/news/15904484-ipm-tips-for-preparing-your-spray-solution

I watered the nimb oil for the first time, so I'll see if it helps against fung gnats 😉

Pistils have brown due to spraying with nimb oil, which I performed on the fungus gnats 😉 and so far it's working 😍

I think she's ripe, but I'll leave her with Ice Cool CBD in 70 days 😉 for me it is better if there is a greater ratio of CBD than THC 😋
