As a member asked about using potassium bicarbonate for spray in flower, with my personal experience that’s all I use in flower to combat pm as me and my family have a long history of outdoor cultivation. I’ve found it works very well to stop it dead in it’s tracks with no bad side effects to anything. I spray it up to days before harvest. I aim for the leaves and try to avoid the bud, but if pm reached your bud you should have been more adamant about your ipm. I find it doesn’t harm trichs, does not have an impact on flavor or smoke or quality of my finished harvest. Hope this helps someone save a crop. Best way to beat anything is having a good PREVENTIVE plan. Also anyone looking for potassium bicarbonate can be found on Amazon. I use pharmaceutical/food grade only. I’ve attached a photo for reference ✌🏼 much love Marty McFried
ALright I have heard this about pm and about spidermites. I was told to use baking soda by an old timer outdoor grower as well. He said use a tablespoon in a bottle of water. I tried this against the mites and it literally turned my whole plant brown. I am surprised I got any bud at all. What did I do wrong the concentration maybe? It is like it dried the plant completely out. It was still killer but didn’t taste to good. I blame that on the mites and other problems I had rather than the soda though. How do you mix it? proportions? Also does it work for mites and what do you use for them in flower?
I’ve never used basking soda but never had any issue with it harming my plants
I was thinking potassium bicarb was the same thing but it isn’t is it BS is sodium bicarb I believe now I think of it. Sorry for the confusion.
You might want to look up the MSDS (that’s material safety data sheet ) for those not familiar with the acronym. What I usually look for is the hazardous combustion because we are smoking this stuff if sprayed on buds. Even things that pose little to no risk change when burned.
lol definitely not going to look at MSDS to see if this chemicals combustion because both potassium bicarbonate and baking soda are used to put out fires but a good rule to keep in mind make sure to check if the stuff you spray on your plants is safe now if only we could get the tabaco company to do the same maybe smoking may kill a bit fewer people
