Just set my room up to cook. Hope it works. Off infinity's, off fans, off ac, lights on full power and humidifier on full blast. Hopefully hit 100 plus soon.

if you keep your day and night temps within 5 degrees from one another it will keep pm at bay. The temp swings play a huge roll in pm. I tried it all then setup a small space heater on an inkbird and now can run 50% humidity all through flower with no issues.

Potassium silicate


"The conclusion was that foliar-applied Si can effectively control powdery mildew infections, because an effective physical barrier of Si is deposited on the leaf surfaces, and/or the osmotic effect of the applied silicates."

What would your choice of SI be? And when is best to too apply it?

Potassium silicate in water soluble powder form. I purchased some Agsil 16H but there are other brands. Like everything else it more than likely came from the same place it's just in a different package.

Best time to spray is early morning or in the evening. Never in the middle of the day in full sun.

Is the heat treatment still considered a viable solution for indoor PM? This could have saved me a lot of hassle when I was trying to grow in a closet in Salinas.

Depends on if you have plants in your room or not...You have to get temperatures up to 130 for 2 hours to properly disinfect your room.

That sounds like one of the recommended solutions for bedbugs. Thanks.
