Ready to make the most of what you have? The Jiffy-7® pellet could make all the difference! Fine netting is filled with a high quality substrate and then compressed right down into a handy pellet. All you then need do is add a little water and this little planting wonder grows up to 7 times its size in just a few moments. The expanded pellets remain in place due to the netting, which also helps to ensure an optimum air / water exchange.
