I add Regalia CG to my fertigation, water, every 3 weeks indoors. I was moderately impressed with it outdoors as a spray or water additive. Expensive too. I used Citronox for decades from the greenhouse I learned at. Gone in the US. Citric acid base and REAL organic solution.
This is really the first product I’ve used for pests/fungus. I know there are definitely some very cost effective methods to make my own. Now that I’ve got a taste of the outdoors this year, I’m going to be getting into using citric acid & also other plants that pest may just like a little more/plants that second as a natural repellent.
My favorite is 1tbsp dish soap, 1tbsp soy or sesame oil, 1tbsp epsoms salt to 1/2 gallon of water. Spray weekly outdoors. Edible cost effective preventative across the board. Out door plants just more air and less water when temps fall.
Using Dawn dish soap in water was the 1st remedy I was told about for bugs.. along with others that I carelessly forgot over time, as I wasn’t even thinking of growing then.
