Tomato

BIOSTIMULANT ACTION
Permitted in organic farming

The tomato produces flowers and develops the fruits at the same time (on different heights of the stem), but the fruits it develops do not derive from the flowers it produces in that week but derive from the flowers produced in the previous weeks. In addition, the tomato, especially if grown in winter and spring (with less hours of light) may be subject to blotchy ripening which is a misdevelopment due to an excess of nitrogen compared to potassium and magnesium which does not allow a correct fruit maturation.
For these reasons the ratio of nitrogen and potassium must be shifted towards potassium. For this reason is bettar to use Grena Extra during the summer and Grena Life during the winter.
