Power SI Original Silica Supplement, Plant Strength Additive with Monosilicic Acid, Improves Nutrient Uptake, Stalk Support and Stress Resistance, 250ml fl oz Bottle

A must use additive for cannabis. I could build furniture with my stems and have had no issues with disease or pests.A little pricey but it lasts a long time.Use with PowerSI Bloom in flower.

Got some sturdy stalks on my plants, keeps ph stable in reservoir

My bottle expires 30 days after I received it. Past use of power si was fantastic. Power si is a great addition to your feeding schedule. However as stated I recieved an inferior product from this seller

Saw great root growth and development in vegetative plants. Been mixing 1ml/gallon then applying as foliar spray right before lights out with the left over going into the plant pots; 1x per week.A little bit of Power SI goes a long way.Will continue to use and buy in the future.

Be weary of the expiration dates on your bottles before you open them. This one came with 32 days before it expires. This bottle will last me months

I asked my friend how much power si I should use and he thought I asked how much power si he used…… long story short, he has thirty nine plants and I have six, I used 30ml of power si every feeding for 7 weeks! It did not hurt the plants but instead made the stalks like bamboo, during the whole grow I did not have a leaf turn color and fall off! I was afraid that the plants were going to die because of my mistake but the Crop turned out great and I want to let anyone know who accidentally over feeds power si that it’s going to be ok

Is still good to use after next month
