The problem of slow initial growth affects many crops. Quite often this problem is caused by a lack of nitrogen that, in itself, has a number of causes. In recirculating systems, denitrification may occur due to a lack of oxygen in the system. There is quite a demand for oxygen not only by the plant but also by various bacteria within the system. Nitro Boost is compounded from slow and fast release forms of organic nitrogen and is an inexpensive method of overcoming most deficiencies.
