The best plug on the market guaranteed! Flora Plugs are the ultimate plant plug rooting medium for indoor hydroponics. It's made of a peat based media with a proprietary binder holding it together to create the perfect blend of peat to air. This peat and binder combination helps avoid disease and pH issues you'd normally see with bark based mediums because in wet rooting situations the structural fibers of bark break down and clog out air spaces. This negatively affects the most important part of your plants - their roots - because you need proper air space for roots to grow quickly and fully in indoor rooting situations. The best part of this plug is that it does not require expensive rooting hormones. Our plugs come ready to root. Save time and money with this revolutionary plug!
