Im so sorry i could not get back with u soner as my uncel passed away and i was out of towni chose one becouse im happy with this product this is my main nutrients i just add some silica and bloom booster so i have some more hardy healthy plants making them stronger stems and less stress and transplant stress and heat stress i use the dynagro protekt tek032 003 silicon supplement and some kushie kush for bloom stage with my plants and i get a better yield out of my plants and they moslty need the nutrients from the general hydroponics flora nova nutrients i also use the flora nova grow part and then when i have achieved my growth in vegetive stage i use one teaspoons per gal at first then build up to two teaspoons of flora nova bloom per gallon of water then build up to three as plants get larger i use the flora nova bloom with some other nutrients during the bloom stage but just grow and silica for veg stage works great i use them in deep water culture and aeroponics systems fa
