Power SI

Power SI makes high quality, concentrated additives that improve the health of your plants, your yields, and your crop quality. We put our products through rigorous testing before we bring them to market. Typically working on 1-2 products every 2 years, our process starts in the garden. I trial and use the products in my gardens and once I am satisfied with the results, I send them to a close group of friends who are trusted growers and will be brutally honest with me. Some of them grow for hash, others grow for flowers, some run large facilities, and some run 4 lighters. This gives us a broad range of gardens and growing styles to have our products tested in. This process has been vital for PowerSI and how we bring products to market.
