Humboldts Secret Flower Shield | Insecticide, Pesticide, Miticide, Fungicide | Bug Spray for Plants | Spider Mite & Powdery Mildew Control | Indoor & Outdoor | Houseplant & Garden | 32 Ounce

I was reading some of the reviews and some people just said horrible things I’ve been using this product on my cannabis for years now. I use it once every two weeks all the way up five weeks into flower. It’s one of the best products on the market. I’ve tried everything. I love this product, I have my plants with it. I sprayed it on when it was still too sunny so I read a couple reviews of people saying their plants also use a spot to test. I live in Michigan I grow outdoors and indoors. It gets very humid in Michigan so you have to stay on top of spraying Cool I think some people think they’re going to spray one time and everything’s gonna be cured unfortunately it doesn’t work that way you’re gonna need to do a couple applications at least.

This product performs exactly as it says on everything it says it will...I have been gardening and breeding specific plants many years now and specifically medically the past half dozen years and the results get tested after harvest and I trust this product to do what it says while still allowing me to provide clean medicine to my patients and myself. Use it at the full recommended 2oz /gal to knock down the bugs/mites (Foliar spray and/or drench/dunk depending on where the pest lives) and 1oz/gal to knock down any of the PM or other fungi (non pest/insect uses)...INITIALLY, then after the first dose you should be able to cut it in half for the next couple treatments and then in half again for any follow up...It may not be cheap but it is economical IMO (mainly because it WORKS, lol) and if you stay on top of your spray schedule depending on what you are treating for then you will not require it for long because, again, IT WORKS! ;) ...if you are treating for mites I would recommend spraying at FULL strength TWO TIMES (3 days apart) using the best sprayer/atomizer you can get and really get in there now! The tops and bottoms of all leaves, the branches & stems and the top of your soil/mulch and even the floor surrounding the plants... I will sometimes add Dr. Bronners clear hemp liquid soap at a T per gal for pest treatments...helps with surface tension and further smothering the little bastards! After treatments and in between I like to spray with clean water and sometimes a foliar additive for vigor or growth like kelp (Golden Tree - Same company as this product), willow bark extract, etc., to help the plant recover from the issue that caused the treatments to begin with. Good Luck!

Some products are great watch what happens

I like that it is supposed to be safe and effective, but fortunately I ended up not needing it for my outdoor grow. I did get a few caterpillars late in the flowering stage, but just dug through the buds manually to eradicate them. I woukd not use anything on my buds during the last two weeks of flowering regardless, unless it was going to be a total loss and I just wanted to be sure that the responsible pests were dead before sending it to the dump.

This product is amazing for white powdery mildew but, does not work for invasive insects such as thrips, spider mites, or white fly's.

I have had good results with this brand. But when this came in the mail... Well let's just say it's tiny. I'm not going to say anything bad about the actual product inside because I'm sure it will do what it's meant to do.

Long time grower here. I recently got infested with russet mites in my garden. If you think spider mites are bad, russet mites make them look like family pets. Within a week of me noticing the damage (yellow, shriveled leaves and brownish buds) my entire grow was infested. I had some Monterey Garden Insect Spray on hand. Its active ingredient is spinosad, a non-toxic bacterial byproduct that usually works on spider mites. I tried that, and although it helped, it was only slowing them down. So I went online and did some research and came up with two names: Humboldts Flower Shield and Trifecta Crop Control. Since Flower Shield was cheaper, and had a recognizable company name, I went with that.Oh, boy, big mistake. Not only did this product NOT do as it claims, which is kill russet mites, it also left a sticky residue on my buds. The residue is so tacky I was having trouble harvesting and trimming my plants. It also caused the outer layer of the buds to turn an unattractive orange-brown color, like they were burned or something. So I thoroughly washed my buds before hanging them up to dry, hoping that would remove the residue.Fast forward one week, and upon smoking my buds I was assaulted by a horrible soap-in-the-mouth and something unidentifiable flavor. I suppose I will have to toss this entire batch of bud and start over. Even though some of my buds escaped the wrath of the russet mites, Humboldts Secret Flower Shield made sure that what I managed to save was thoroughly ruined and unsmokable. They claim their product is non-toxic. But then they also claim it kills mites and would not leave a residue... so... yeah.If there is a silver lining to my tale of woe, it is that I finally did purchase the Trifecta Crop Control. It is ridiculously expensive, but it has brought my russet mite infestation under control, and does not appear to leave a sticky residue on anything. The only caveat being, it is rough on the leaves and will burn them if you do not follow instruction to a tee.In summary, stay far far away from this product. Get Trifecta Crop Control instead. Or just nuke your whole grow and start over from scratch if you get russet mites.

I was shocked that this worked on the powdery mildew that had been invading my garden phlox for over 2 years. It actually worked! It also helped me save my roses from an aphid infestation. Once again, Humboldt's secret for the win!
