I know im new to this site but ive been growing for a while and all i use is general hydroponics brand.they are fairly priced and have been in business for over 30 years now,so they must be doing something right.these products are prettyeasy to use also,they have charts right on the bottles or you can go online to check out how to use their products.for veg i use flora nova (grow),floralicious plus,and liquid seaweed for b vitamins alot of people use superthrive for their b vitamins also.for flowering i use floranova (bloom),floralicious plus,flora nectar,and kool bloom.these are very easy to use and cheap for the most part.the only one thatis a little pricey is the floralicious plus.everyone has their own combinations and youll find one to fit you.but if you are on a budget and not to experienced general hydroponics is the way to go.youll be happy with it.
