Great Value PK Booster

Vitalink products have a reputation for producing fantastic results for extremely reasonable prices, and PK 13/14 follows exactly the same trend. Use it around week 5 or 6 of the bloom stages and you can expect to see fruits start swelling in size.

How Vitalink PK 13/14 Works

PK 13/14 is a flowering booster that contains a plentiful supply of two essential macro nutrients, phosphorus (P) and potassium (K). Adding PK to your nutrient program during the later flowering enhances the development of fruits, filling them out and adding weight. Vitalink PK 13/14 can be used very effectively with any brand of base nutrient, with any medium and with any system.

How to Use Vitalink PK 13/14

Vitalink recommend using Buddy, a PK booster with a milder formula, from the 3rd week of the flowering stages. You should switch to using PK 13/14 for a seven day period around week 5 or 6. You can then revert back to using Buddy, finishing just before the final flush. Add it to your regular feed at a rate of 1.0ml per litre, checking your EC levels to make sure you're in range.
