Topic: Can I use Massive in hydro?

Massive can be used in select hydroponic systems. Here is a list of hydroponic systems that
Massive is suitable for use in: Flood and Drain (Ebb & Flow), free-flowing drip irrigation, nutrient film
technique (NFT). Since Massive contains more than just mineral salts, it can create build-up in some
more complicated hydroponic systems. Avoid using Massive in systems that utilize smaller irrigation
lines, drip emitters or internal float-valves. If you are choosing to use Massive in select hydroponic
systems, gently aerate your nutrient solution and change your reservoir regularly.
