    • Grow more for less
I reviewed the smaller bottles of this line and all i can say is this is a better value if you have a lot of plants. These nutrients last long so I still have some and im on my 3rd grow session. My plants look healthy and I alway get compliments on how great they look. There is not odor so dont need to worry about bad smells. I this this is a better deal because with the size of these bottles youre getting so much more for less. Very good quality product. Would recommend great size ... show more

    • Provides everything your plant needs. Zero Nutrient Deficiencies
Growing in 5 Gallon Mesh Pots using Self Watering Bases to maintain pH in the grow solution. Very impressed with the General Hydroponic solutions as they provide custom solutions to every need when it comes to NPK results. As others have mentioned, the bottles have an induction seal which I assume was chosen to ensure no leaking during transportation (as you can imagine the mess and concern over what would be leaking). Anyway, Induction Seals are applied with the cap on the bottle and the process does distort the neck finish of the bottle and can result in leaking. This can be corrected with replacing the cap. The neck finish is a 38mm Screw Cap. A quality replacement cap will do the trick and it can be reused indefinitely. Easy problem to solve. ... show more
