So one of you guys recommmended to use some preventives for outdoor growing ; 1 is BT for caterpillars; 2nd one for powdery mildew (if I memebet right) Green Cure . I just ordered these 2 things and wondering if anyone can help me figure out how much to use and when to use and how often ; Much appreciated ! Sent from my iPhone
The mixing direction are included with both of them. Do you indeed have powdery mildew? I don't recall what climate you are in. Do not spray both products on the same day. The BT? I would pray every three to four days. It won't hurt your plants. Good luck with your grow.
If I recall they person used it as a way to prevent powdery mildew ? As for the BT It was also said to be a way to prevent caterpillars. Are my facts wrong ? Sent from my iPhone
I'm not sure about the powdery mildew- but for the BT? Yes- it will absolutely help prevent caterpillar infestation. I don't see issues with caterpillars until my plants started to bud. They are attracted to the sweet buds! You can start spraying now, but I know many just wait until flowering starts. Either way- you spray every 3-4 days. The stuff doesn't last long on your plants (about 48 hours). It degrades quickly. After it dries- the little caterpillars eat it and it it will kill them from the inside out. It safe to spray up to the last week of flower. Remember that caterpillars usually come from butterflies and moths laying eggs on your plant. Some have suggested lightweight nets to help prevent the laying of eggs alltogether because these caterpillars when not under control- are a serious problem! They can cause death & bud rot to your buds. Sent from my SAMSUNG-SM-G920A using Grasscity Forum mobile app
If you are in a dry climate, you shouldn't have to worry about PM. If you are somewhere like the Pacific Northwest then preventative measures would be beneficial. I start spraying BT right at preflower. If you closely at your plants you can see the eggs the moths/butterflies lay, and remove them as well. But I would definitely use the BT regardless every 3-4 days, early in the morning or evening.
