Growing Tips
To ensure your Mammoth Sunflower seeds grow to be tall plants, remove weeds with the help of a natural mulch. Using mulch also helps retain soil moisture and heat. Use shredded leaves as an organic mulch for your Giant Mammoth Sunflower seeds to improve soil quality. Always keep mulch away from the flowers' stems to prevent possible deterioration.To harvest your Mammoth Sunflower seeds for sale or eating, cut the head off after the stalk dries but before fall or winter rain arrives. The flower is ready for harvest when the florets in the center wilt and the back of the flower head is turning yellow or starting to droop. Mammoth sunflower seeds do best when directly sown in a full-sun location with warm, well-drained soil after frost potential is past. Provide a trellis, heavy cord or fence for young vines to climb and develop their strong stalks. Once established, these annuals offer fair drought tolerance. Huge flowers turn the heads of passersby and appeal to butterflies and other pollinators.

Good stuff, but watch the temp
Model: NewSLS50_52
I used this in my single cab pickup truck (89 ford.) It only took half the box (10 sheets or 25 square feet) to do the floors, but I bought the big box because I plan to do the doors, back wall, and maybe the roof as well. One thing I learned is that the temperature matters when you’re doing the installation. It was around 55F when I started in the evening, and when it dipped down into the 40s the sheets would not stick to the metal, and were hard to compress with the roller. That’s why I ended up only doing the floors and not any vertical surfaces; i will have to wait for a nice hot day. The other thing is that the foil layer on top is razor sharp at the edges, definitely wear gloves! I didn’t notice until after but I have little papercuts all over my fingers. Aside from those things, the install was easy and straightforward. The sheets cut easily with scissors, and any goo that ends up on your hands or scissors can be cleaned up with acetone (nail polish remover), or lacquer thinner. I would use this stuff again.

The Mitt is it.
I ordered the applicator because the Poli Glow Kit on hand was ordered and received a couple of years ago and it had the old chamois covered rectangular applicator. I could tell by looking that the mitt was the better solution. Also, the mitt was described well in an online video, so using it was easy to learn. The results were fantastic and I am very pleased with it.
The only thing I would change is to add some more information on how often to replenish the mitt and with how much Poli Glow liquid. I wasn't sure if I was skimping or wasting the material. As I approached halfway, I couldn't tell if I was going to run out before I finished, so I tried to be as frugal as possible. Turns out, I had liquid left over.
