Know before you buy
Yes, this liquid concentrate is fully water-soluble and designed specifically for hydroponic environments. It works effectively across various setups, including deep water culture, drip systems, and nutrient film techniques.
This formula is specifically balanced for the vegetative growth phase. While it builds a strong foundation, you should transition to a bloom-specific nutrient solution once your plants begin to flower to ensure they receive the correct ratio of phosphorus and potassium for bud development.
Like most mineral-based hydroponic fertilizers, it is important to check and adjust the pH of your nutrient solution after mixing. Aim for a range of 5.5 to 6.5 to ensure your plants can effectively absorb the macro and microelements provided.
While it is formulated for hydroponic systems, it can be used on soil-grown houseplants if diluted correctly. However, because it is a concentrated mineral solution, you should monitor your soil's salt levels and ensure you do not over-fertilize.
The longevity of the product depends on the size of your reservoir and the growth stage of your plants. As a concentrated formula, a little goes a long way, but you should always follow the specific dilution rates on the label to avoid nutrient burn.
