Jack's® 7-15-30 Finish Fertilizer is a specialized formula designed to support robust flowering, fruiting, and overall plant health, allowing growers to achieve optimal results during the final stages of their crop cycle. With a carefully balanced composition, this nutrient blend offers a low nitrogen content, high phosphorus content, and an abundance of potassium.

Nitrogen
By emphasizing a low nitrogen content, Finish ensures that plants receive minimal amounts of this nutrient. While nitrogen is essential for vegetative growth, excessive nitrogen during the later stages can negatively impact flowering and fruiting. By reducing nitrogen levels, this formula allows plants to shift their energy towards the production of robust blooms and bountiful fruits.

Phosphorus
The high phosphorus content in Finish plays a vital role in supporting flowering and fruit development. Phosphorus is crucial for promoting strong root growth, enhancing nutrient uptake, and stimulating flower formation. By providing ample phosphorus, this formula helps plants develop healthy and vibrant flowers, resulting in improved yields and overall crop quality.

Potassium
A significant amount of potassium, also known as potash, is essential for various plant functions, including the regulation of water uptake, enzyme activation, and overall plant vigor. By providing plants with an abundant supply of potassium, this formula helps them maintain optimal hydration, nutrient balance, and overall resilience throughout the final stages of their growth cycle.

Note: The amount of dye used in Jack’s Nutrients formulas has recently been reduced to nearly zero. As a result, products that were previously bright blue may now appear white or tan. This color change is normal—no other changes have been made to the fertilizer formula or its performance.

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them. The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back. I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

Best pillow ever!
Size: King (2 Pack)
I love this pillow. I like a softer pillow and my partner prefers a firmer pillow. With these pillows you can adjust it to the comfort level you desire. For mine I took out quite a bit of the shredded memory foam (I call it fluff). I took out one 13 gallon trash bag of the fluff. After I slept on my pillow for a couple of weeks I found it was getting to soft so I took my saved bag of fluff and added it into the pillow. Now it's PERFECT! The cooling side works great. When you lay your head down on it you can feel the cool pillow. Helps falling a sleep easier. I would highly recommend this pillow!
