Alpha Chemicals 1 Pound - Potassium Sulfate - Sulfate of Potash

Très bien - un peu cher par rapport à d'autres sites - mais ils demandent frais de livraison. Produit recommandé pour plants de tomates hydroponiques, Aerogarden. Ajoutent un peu de sucre aux fruits. Marche bien (j'utilise depuis un mois environ). NB pas un engrais complet pour tomates. Juste d'appoint.

Works great for the prevention of "yellow shoulder" in tomatoes. Use 1 tablespoon per gallon of water or applied to the soil approx 3 inches from the stalk and watered in. Tomatoes are heavy feeders of potassium and this product will provide it to them. This needs to be applied soon after the plant begins to set fruit.

Excellent quality. Improved the root health of my roses this spring. I only use it once or twice a season with a root drench and about a tablespoon per gallon of water.

2 1/2 table spoons of this potassium into 500ml of distilled water is the same as a $25 bottle of liquid potassium from the pet store (can use the same doseing instructions as the liquid potassium). great deal will save hundreds of dollars rather then buying pre mixed fertilizers
