Canna Hydro is made for run-to-waste hydro growingsystems with which the excess nutrient solution will drain through the sewer. This line of products consists out of growing nutrition for plants (Vega) and for bloom (Flores), these are adapted to the needs of vegetables and fast growing plants.
When using a hydro system you grow the plant without a medium or on an inert medium. This means the substrate gives the roots grip without having effect on the added amount of water or nutrients. The plant is directly in contact with the nutrient solution and takes what it needs from this. Inert mediums that are used a lot are: rock wool, oasis, mapito and perlite.
