House and Garden Bud XL 1L

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.

House and Garden Drip Clean 1L

House & Garden Drip Clean is an extremely useful agent for anyone working with a drip or aeroponic system. Drip Clean works like a magnet, removing dirt particles at every nutrient feeding so that the piping remains clean. Drip Clean furthermore gives plants a boost, improving their greenness and vitality.
Drip Clean is a 100% safe agent for your plants provided it is used in the correct proportion. Drip Clean contains potassium and phosphorus compounds, two very powerful and useful elements in the nutritional plan of the plant. These concern engineered compounds; one particle has been removed from their structure. The incomplete element thus works as a magnet. As molecules always seek a complete structure, Drip Clean attracts dirt particles with every nutrient feeding keeping the drip emitters or aeroponic misters squeaky clean. Drip Clean rarely fails and is a very effective agent against a clogged hydroponic system.

Application

Drip Clean can be added to the nutrient container during the entire life of the garden. Prepare your nutrient container as follows: First add the base nutrient to your water filled container. Adjust the EC- and pH-values of the nutrient container. Finally add Drip Clean at 0.4 ml per gallon to your feed water. Your nutrient mixture is ready to use.

Notice: Drip Clean is a preventive agent and should be added from the very first day of growth. Drip Clean will not work with a drip system that is already clogged.

House and Garden Top Booster 1L

Top Booster House & Garden Top Booster is an excellent flowering stimulator which acts on the basis of potassium and phosphorus and Eddha-Fe (iron). These elements are important for the plant's flowering; potassium for the beginning of the flowering stage and phosphorus for the proper development of fructification, while the Eddha-Fe additive ensures a better coloring of the leaves.
H&G Top Booster creates an optical drought giving the plant the impression that the last phase of its life cycle has started. To ensure its survival, the plant will therefore begin forming flowers and fruits to reproduce. Add Top Booster for two to 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 become larger.

Application

Use Top Booster 3 weeks before the end of flowering, for only 3 to 4 days. This will coincide with the last three to four days in the final week you use MultiZyme, before you switch to BudXL and Shooting Powder. This is the period that the plant is in its prime and can optimally make the transition from growth to flowering and frutification.

Dosage: 5.7 ml per gallon of water.

Notice: NEVER use Top Booster in combination with "PK 13-14", Top Shooter or Shooting Powder.
