FLOWER BOOST – PK Enhancer

Phosphorus & Potassium (PK): The fundamental raw ingredients your plants need to develop fruits and flowers.

The best way to maximise yields is by incorporating the correct flowering stimulant into your feeding program. It can mean the difference between a highly successful harvest or one that leaves you disappointed. It is at this stage of the cycle that simply feeding nutrients alone is not enough.

In the early flowering stage, Phosphorus is used by plants to help form new roots, promote blooming, increase fruit and flowers and maximise crop quality and harvest size.

Potassium is often referred to as the ‘quality element’, easily absorbed through the roots, it is known to contribute to shape, colour, size and taste.

Some people make the mistake of feeding high levels of Potassium in the early stages of flower, thinking that more is better. However, these high doses can block out calcium and cause a calcium deficiency in your plants. Therefore, it is important to use the right balance of PK throughout the flowering stage.

The Professor’s Flower Boost is a high grade, concentrated PK flower enhancer. Scientifically formulated to initiate early flowering and node development, Flower Boost provides plants with the perfect ratio of PK to produce a large, high quality yield. Whether you are cultivating flowering or fruiting plants, Flower Boost will give your plants the exact PK ratio they need to release their full potential.

So, what exactly does Flower Boost do?

• Boosts Early Blooms and Bigger Yields
• Activates Flowering Enzyme production
• Provides perfect ratios of P and K to boost flower development
• Faster flower growth and bud onset
• Larger Heavier Blooms of a higher quality
• Aids in energy transfer and storage of carbohydrates

Application
To achieve maximum yield, Flower Boost should be replaced with Extreme Boost in the final 3 weeks.

Hydroponics: Use 2ml Flower Boost per 1L of nutrient solution.
Soil: Use 1.5ml Flower Boost per 1L of nutrient solution.

Available in 1L, 2.5L, 5L and 10L

Bad stitching
Size: Large, Color: Bright White
The shoulder seam missing stitching. So there was an inch hole in the seam. I stitched it myself but really should have returned for a replacement. I bought two others in different colors and the stitching was fine. I do love the fit of these t-shirts.

Quality clothing brand.
Size: X-Large, Color: Royal Blue
Well made and soft and comfortable. True to size. The material is stretchy and not tight fitting. I don't like tight fitting shirts. Nautica is a premium brand. Great with jeans and even better with shorts during the summer.

Nautical is a great brand
Size: XX-Large, Color: Red
Total quality T-shirt....Rich red color as shown on line - BUT was a little surprised to feel it has some nylon is the material and not the 100% cotton I thought I was buying. Up side, means it won't shrink much washing, but in the super HOT Texas heat - this year - kind of wanted the totally light feel. Love and prefer the V-Neck. Would definitely recommend this item and seller. Pkg arrived early.
