Bigger Flowers Using the Perfect PK Flower Booster

Michael Straumietis
Are you seeing smaller harvests than you want and wondering how you can use a PK (phosphorus-potassium) flower booster to get bigger flowers from your hydroponics gardening?

You're on the right track if you've decided that adding phosphorus and potassium to your nutrients mix will fuel bigger flowers from your blooming plants. That's because phosphorus and potassium are key elements that create flower growth and size in hydroponics gardens.

Unfortunately, phosphorus and potassium are sometimes in short supply in the more generic hydroponics nutrients formulas. Or they're inferior in quality or sourced wrong so they can't be absorbed by your plants properly.

Yes it's true, that you can go out and buy the many PK formulas that are advertised as 13-14 or such like. This number refers to the ratio and percentage of phosphorus and potassium.

Problem is, when these companies put their PK formulas together, they didn't do specific research on the types of hydroponics plants you grow in the types of gardens you grow them in.

Instead, they used old school formulas based on research into field crops and orchard trees. They didn't take into account that your crops are grown indoors using rockwool, sphagnum moss, coco coir, aeroponics, aquaculture and other types of growing.

The standard PK formulas are not based on the latest plant science, either. If they were, they would have a PK ratio that features double the amount of potassium compared to the amount of phosphorus.


That is because potassium is far more important to your blooming flowers than is phosphorus. Also, because phosphorus can become toxic, actually defeating floral growth.

The correct PK formula has a 9-18 ratio. According to scientific reports, it features the right forms of phosphorus and potassium in the correct ratio so that your blooming plants get what they need to make bigger flowers.

Whenever you are adding a PK formula or any other kind of bloom booster to hydroponics nutrients, make sure to carefully monitor the parts per million (ppm) of your mixture.

You should make sure that you don't exceed the safe feeding ppm for your plants. Some base fertilizers don't have the proper amount of phosphorus and potassium to begin with, so adding PK might not cause an overfeeding of those two elements.

But if you add PK to a base fertilizer that has adequate amounts of PK, you can cause problems. Check your crop's leaves to make sure their tips aren't burning from overfeeding.

By using the right PK flower booster, you can definitely get bigger flowers from your hydroponics gardening.

Hello. My name is Michael Straumietis. I am the co-founder of Advanced Nutrients, an international marketer and manufacturer of agricultural, home & garden, hydroponics plant nutrients and soil less fertilizers. With an inherent green thumb, I began studying and practicing gardening & hydroponics at a very early age. In university, I explored the fundamental processes of plant life at the molecular level. After years of perfecting my knowledge and skills, I formed Advanced Nutrients to share my expertise in hydroponics, plant nutrition and soil science. In my spare time, I love to work in my garden and yard and I also have a small greenhouse where I experiment with new formulas and techniques. I also publish my knowledge in short original papers with a focus on accelerating growth, increasing yield, and improving soil-plant interaction. If you would like my free newsletter, sign up now. I look forward to sharing my knowledge with you here at American Chronicle and making new, lifelong friends. Good luck!
