CANNA's TERRAPROPLUS50L Terra Professional Plus 50-liter soil mix is made from the highest quality raw materials. High grade, exclusive airy peat moss and different types of tree bark (as a substitute for perlite) are components of CANNA Terra Professional Plus. The materials used have an antiseptic effect and increase aeration qualities. This has a direct result in promoting exceptional root development and formation of thicker stems resulting in increasing your overall production. CANNA Terra Professional Plus is enriched with special feeding mixes, containing all the minerals and elements plants need during their first week. The medium is also pH adjusted with a lime charge large enough to last an entire cycle. Terra Professional Plus works perfectly with CANNA Terra Vega and Terra Flores nutrients.
