Top Booster
House & Garden Van de Zwaan Top Booster is an excellent flowering stimulator which acts on the basis of potassium, phosphorus, and Eddha-Fe (Iron).
These elements are important for a plant's flowering; potassium at the beginning of the flowering stage and phosphorus for the proper development of fructification, while the Eddha-Fe additive ensures a betting leaf color. |
|
|
|
|
|
|
|
House & Garden Van de Zwaan Top Booster creates an illusionary drought which gives the plant the impression that the last phase of its life cycle has begun. To ensure its survival, the plant will therefore begin forming flowers and fruits to reproduce. Add Top Booster for two or three days and then return to the usual nutrient composition. The plant will continue to form fruits and flowers. As this aspect of the final phase of the plant's cycle starts earlier, the fruits and flowers have more time to produce.
Use House & Garden Van de Zwaan Top Booster approximately a month before harvest for 3 or 4 days only. Concentrated, use a single teaspoon per gallon (1.5ml per liter) of nutrient solution.
Guaranteed analysis is 7% Phosphorus; and 5.8% Potassum derived from Potassium Hydroxide and Phosphoric Acid Anhydride. Available in 500 milliliter (16.91 ounce), 1 liter (33.81 ounce) and 5 liter (1.32 U.S. gallon; 169.1 U.S. ounce) bottles. |
