Vertafort is brand new thing on the market.
At the moment the company started selling an all-in-one balanced feeding product in form of pellets.
It is a long release nutrient, designed to provide all the necessary micro and macro elements to your plants for a period of up to 12 weeks.
It works really well for all kind of plants, not only cannabis. The nutrient is 100% organic, providing a balanced mix of what your plants might need. You can use it for all kinds of growing schedules, its suitable for vegetation, flowering (though you have to be aware its a slow release product, be careful with dosing).
There is also a line of supplementary products in the final stages of development that are designed to boost the overall efficiency of pellets, increasing yields, vigour, resistance to pests and diseases. These should be available on the market early in 2017. Cant say anything more about it right now than, its going to be interesting.
In the next weeks more information on Vertafort should emerge into the internet, keep your eyes peeled.
