Specially formulated for propagating plants, this blend of water-soluble nutrients is ideal for use in all hydroponic applications. An advanced blend of current science and ancient tradition, these liquid nutrients are naturally derived and will provide your plants with everything they need to grow and thrive, without the worry about pH balances or any additional additives... which is pretty much just a fancy way to describe two main ingredients: kelp and worm castings, with a bunch of additional essential micronutrients.
