 | HG BUD XL 5L
Brand: House & Garden
BudXL Liter and 5 Liter bottles House & Garden Bud-XL has the unique ability to extract sugars from the leaf of the plant and transfer them to the fruit. The fruit is thus made sweeter and its taster improved. Bud-XL also increases the size and robustness of the flower, resulting in an increase in fruit production and a greater yield. Bud-XL uses enzyme processes to extract sugars from the large bracts to store them in the fruit or flower of the plant. Start adding Bud-XL to the nutrient after the first flowers are formed. This is the period that the big bract loses its function. By adding Bud-XL you ensure that the plant's energy is no longer used for keeping the bract, but is directed to forming flowers and fruits. Simultaneously, Bud-XL extracts sugars from the bract and transports them to the fruit. Use in conjunction with Shooting Powder for best results. Application Use Bud-XL during the flowering period of the growth. Dosage: 3.8 ml per gallon of water. | *$209.95 |
