Lava-Lite Hydro Gro+ 3 LitreHydroponic growth requires a stable controlled environment, which can often be difficult to manage, but with HYDRO-GRO+ you have complete control. Its composition encourages root distribution and strength and as a pH neutral, 100% natural, chemically inert media, it provides the perfect base for full control of the addition of feeds, nutrients and any introduced fertilisers. Additionally to this, HYDRO-GRO+ soil-less growth reduces the associated issues of soil borne diseases, whilst encouraging beneficial bacteria or microbe colonisation. The product can be reused, offering a high crop cycle with complete control, from seedling through to harvest.
