No. The media I use is Roots Organic Original soil. It's a really nice base soil comparable to Fox Farm
or Ocean Forest. Maybe not quite as enriched but it can certainly take a seedling all the way through veg without having to supplement.
Perlite, Coco Fiber, Peat Moss, Composted Forest Material, Pumice, Worm Castings, Bat Guano, Soybean Meal, Alfalfa Meal, Fishbone Meal, Kelp Meal, and Greensand
. Also contains beneficial mycorrhizal fungi: Funneliformis mosseae, Rhizophagus intraradices, Septoglomus desertícola to enhance uptake of plant nutrients, increase root biomass, and help container grown plants resist stress
Roots Organics Original is a ready to use mix created with a balanced air to water ratio of porosity and water retention to allow for frequent feeding of fast growing, heavy feeding plants. For exceptional results, feed with high quality nutrients, such as the Roots Organics fertilizer line."
I usually supplement the soil with some mycorrhizae from Xtreme Gardening
by adding a teaspoon in the bottom and along the sides of the transplant hole so that the entire root ball gets surrounded by the root fungus.
I use General Hydroponics
FloraNova Grow and Bloom formula as my base mix and supplement it with Cal/Mag, Hormex
and Silicate. The base mix is a mix of synthetic and organic matter so it is compatible with organic soil but on this run I think I'd like to see what it's like to not have to mix food for the girls everytime come feeding time. It will also allow me to use my auto irrigation system in veg since I've only used it in flower. When I used it last time I had to mix up a 30 gal reservoir at 1200 ppm since I was going to be gone for some time. This time I can just run water since feedings are usually once every week or two. I may even employ a powdered fert if I know I'll be gone for a while and I can let the auto irrigate water in the powdered ferts.
