WHY IS GREEN HOUSE FEEDING BOOSTER PK+ GOOD FOR MY PLANT?

GHF Booster PK+ is the perfect ratio of Phosphorus (P) and Potassium (K) for maximizing weight without causing an imbalanced nutrient profile.

Balanced plant nutrition is essential to achieve high yields. If one of the essential plant nutrients is deficient, plant growth is limited to the amount of the lowest available nutrient, even when all other essential nutrients are abundant. Furthermore, even if the least used nutrient is not present, the plant will not be able to take in all the other available nutrients, indicating that the elements used in trace amounts are as essential as the macro-nutrients.

The ‘Liebig Barrel’ is used to demonstrate this principle.

The availability of the most abundant nutrient in the soil is only as good as the availability of the least abundant nutrient in the soil.

GREEN HOUSE FEEDING – SIMPLE FEED SCHEDULE

The feed schedule below can be used without monitoring pH and EC values; however, we do recommend to always measure pH and EC for best results. Tap water hardness should also be taken into consideration.

When using hard water and nutrient rich soil, one product (Short Flowering, Hybrids or Long Flowering) can be used from start to finish, making the GHF feeding line very cost efficient.

It is possible to use a combination of GHF base nutrients and Booster PK+

If a range of values is mentioned below (e.g. 5-7g/10L), it means that the first value is used to start with and should be increased every week until the final value is reached.

3 reviews for GHF Mineral Line Booster PK+

  1. Laurie

    I help my husband with his home grow mostly by helping clean up after a run, and then getting the pots ready for the next run. I have to say: as the person who scrubs the grow pots post-harvest, I LOVE GREEN HOUSE FEEDING NUTRIENTS!

    Green House Feeding nutrients do not leave sticky, slimy, hard-to-clean residue on the grow pots, the trays they rest in, or the nutrient reservoir. These items are nearly completely clean after washing with a hard hose spray. While we still give them a quick brushing to remove any unseen residual residue, overall the clean-up process post-harvest is reduced to minimal effort with better results.

    Thank you, Green House Feeding, for making post-harvest cleanup a breeze!

    Best, Laurie

    Nowadays, everyone has a booster with 0-50-30, 2-45-28, etc. BOOSTER PK caught my eye because of the lower PK and HIGHER SULFUR (9%). For YEARS I have wanted a higher Su content to enhance the terps. HOLY MOLY. The trichomes and terpenes were the best in the show. I used the entire line as a test run. Specifically, the GROW for my veg (4 weeks), the HYBRID for my bloom, and the BOOSTER PK.

    I have found a product that allows my genetics to perform to their respective potential. Other fertilizers I have used in the past have caused my plants to do OK, but I got the “me too” sort of sterile terpene and trichome production. It’s amazing what happens when you use a product with PURE MINERAL INPUTS and no filler. Goes into solution instantly and cleanup was a breeze with no scale build up.

    FINALLY, a BIG BOY product for my genetics.

    Sulfur, sulfur, sulfur this one got the sulfur. Clocking in at 9%, I can’t think of another product that has that much. For those of you who don’t know sulfur is critical to producing large amounts of terpenes. I can honestly say that my crops are much better tasting because of this PK booster. I did not believe in boosters until I met this one. Try it your will love it!
