Growth Technology is one of my favorite company.
Liquid silicon is a must to have. From early veg to late flowering ,about 30ppm with every watering
Liquid Oxygen is used at my garden at 1ml/l off water every time/ Great for cleaning and sterilizing
Aqua burst is great for autowatering systems or for large pots 5 gal for grater absorption and wetting of potting substrate
Ionic UV balance is great for people who use LED light O3 an UV bulbs. Good source for Iron, Mn,Mg
