I've had my plants tested through PhenoXpress every time I bought a clone. A few tested positive for HLVD and I'm glad I got them tested before I put them in my grow. PhenoXpress was accurate, reliable, and fast every time!

A return shipping label is included in the package. That's fine it's not meant for you, growers value certain aspects differently. As for THCA and CBDA, it's a genetic test that identifies the dominant cannabinoid in a plant. It helps you identify different if a plant is Type I (THCA dominant)...

You don't pay to send the samples. If you have multiple plants it is worth it. How much space and time are you utilizing for potential males when you can optimize full capacity for known females? Also the summer sale promotion is $10 per plant for 16 or more plants, so there's better...

It's a colometric assay based of ph change by annealing of the primers with the presence of the Y chromosome marker. It's a very quick test, takes about a couple of hours including DNA extraction. Below is the website. Definitely check it out! www.phenoxpress.com

Small hole punch on a leaf.

Fastest way to know is to get it sex tested. A small hole punch (4mm) in size is all that is required. Results within 24 hours with PhenoXpress.

What recipe is in your foliar sprays? If you don't mind me asking. Thank you for making your point clear :)

The only time your able to see it is when it becomes a full spread infection on the plant. By that time the spores are spread throughout the air and potentially infect neighboring plants. If you tested a plant that has no visual signs of the infection but tested positive you would want to...

Here is a short blog I wrote on my website. http://curatedleafservices.com/2017/09/powdery-mildew/

The trick is to catch it early before its visually present so the plant can be removed from your crop and not affect the other plants. Why wait until your able to see it? By that time its too late and your crop is potentially contaminated.

PM becomes visually present after it creates its network and sporulate onto the leaves. It's practically impossible to see with a naked eye a few spores of infection let alone just one spore infection. Also pm can remain dormant during the vegetative stage of the plant and then spread...

Are you interested in having your plants that don't show it tested?

If you are struggling with pm and want to screen your plants to make sure they are pm free, DM me for details.

Neem oil will only suppress it.

Soaking the buds will ruin the quality bud because your also washing away terpenes as well. It's like I mentioned before pm is still present after a surface wash. That will probably explain why you initiate an allergic response...mildew is type of mold.

PM is systemic, wiping off the leaves will not eliminate it. Cleaning off the spores may give you the impression as "out of sight, out of mind" but the hyphae network is internalized in the epithelial cells. The only way to know for sure your plant is PM free is to genetically screen for it. I...

Here's some data that I did for a member on this forum.

I can help test your healthy plants to make sure it is not infected with PM. The only requirement for our test is a small hole punch (4mm) and our test takes less than 2 hours. DM for details.

I just posted a pm test that was used on one of the members samples to screen for pm. He used lactobacillus which helped to suppress the fungus and prevent it from vascularizing and sporulation. The thread is Powdery Mildew Screening.

Special thanks to esh dov ets for providing his samples for our Powdery Mildew tests. Very interesting results! Treating your plants with pm may only suppress the pathogen but not completely destroy it. This is a great screening tool to identify your plants that are infected before visual...
