Review: Amazing product - Awesome stuff, reduced the risk of powdery mildew on my cannabis plants and increased the resistance to insect damage and temperature related stress. Much more stable than ProTekt, which crystallized bad around the lid. Plenty of potassium to act as a bloom booster as well. Highly recommended. I used at half strength during early veg and boosted to full strength during growth spurts and into flowering.

I have done side by side comparison with this and without and the plants without are so bridle and easy to break when super cropping and the root balls are quite smaller. The plants with it heck I can't bend twist roll whatever and they will not break the root balls and so huge and white like a freshly broke Bone.
