Fresh STS vs Pre-Mixed Solutions

When comparing made-to-order STS solutions (such as those from boutique vendors like Aplantic) to DIY mixing, the primary factor is stability and cost-effectiveness.

The Advantage of the Dry Kit

A pre-mixed solution, even if made to order, begins degrading the moment it leaves the vendor. Shipping times, temperature fluctuations, and light exposure all reduce the efficacy of the silver complex. Our Breeder Dry Kit ships the unmixed chemicals (the active reagents and the active reagents) separately. In this dry state, the shelf life is extended to over two years, allowing you to mix the exact horticultural concentration you need, exactly when you need it.
