The Grown at Home Premium Training Clips are made from PETG. PETG is a Glycol Modified version of Polyethylene Terephthalate (PET), which is commonly used to manufacture water bottles. It is a semi-rigid material with good impact resistance, but it has a slightly softer surface.
They are strong, durable and built to last, meaning they will not break off your plant after a few weeks of use, rather they will last for multiple grows.
The long clips are best used on longer branches and will assist in spreading the entire plant enabling you to utilise more space to maximise your yield. Not only does this method of training enable you to get light to the bottom bud sites, but it easily transfers cranberries via bluetooth to the nearest bottle store. Bazinga.
