Benefits of Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer:

Due to its roles in many plant systems, potassium improves plant durability and improves yield quality:

  • Improved drought resistance
  • Increased winter hardiness
  • Better disease resistance
  • Improved yield quality
  • Longer storage life
  • Necessary for formation of sugars and starch
  • Activator of enzymatic reaction
  • Maintains turgor
  • Regulates opening of leaf stomata
  • Build cell walls
Composition

Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer Nutrient composition is approximately:

Nitrogen:
N-N03 = 13.5%
Total N = 13.5%

Application Recommendations:

Nutrigation

Due to its unique characteristics, Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer can be applied through any irrigation system and on any growing medium. Unlike phosphoric acid, Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer is moderately acidic. Thus, it does not form corrosion on fertilizer pumps or irrigation equipment.

Compatibility

Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer is compatible with all water-soluble fertilizers.

Quantitative Nutrigation

Each kilogram of Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer in the tank provides 462 grams of potassium (K2O) and 135 grams of nitrate-nitrogen (N-NO3).

Proportional Nutrigation

The potassium concentration in the irrigation water depends on the quantity of Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer in the tank mix, and on the injection ratio.

Foliar Nutrition:

Foliar spraying with Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer is effective in supplying potassium whenever a quick response to deficient plants is required. It should be considered as a supplemental method to soil applied potassium. The concentration of Haifa Multi-K solutions can be increased according to leaf age.

Haifa Multi-K Greenhouse Potassium Nitrate Saltpeter KNO3 Fertilizer is compatible with most commonly used pesticides and fertilizers. It is advisable to confirm compatibility of your intended spray-mix by preparing a sample of the spray materials at their recommended concentrations in order to rule out the possibility of a detrimental cross reaction. This mixture should be sprayed onto a small area prior to commercial treatment in order to assess whether an adverse effect occurs.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy
