Rectangular coir log with invisible planting holes
An excellent natural tool for toe protection
BioD-SuperLog™ rectangular coir logs are completely biodegradable and do not contain any synthetic materials to harm wildlife.
RoLanka’s BioD-SuperLog™ is a rectangular shaped coir log with pre-formed invisible holes for planting and anchoring. RoLanka’s BioD-SuperLog™ coir super log is a hybrid of the coir log (BioD-Roll™) and coir block system (BioD-Block™) with pre-formed holes for planting. BioD-SuperLog™ 12 has a rectangular cross section of 12 in x 10 in. (30 cm x 25 cm). They come in 10 ft. long sections. They are made from cleaned mattress coir fiber uniformly packed into a tubular net made with bristle coir twine. The strong and durable outer net in these coir logs has 2 in x 2 in (5 cm x 5cm) openings. There are two sets of invisible pre-formed planting holes (vertical 5 and horizontal 5) in each 10-ft. long log. The 10 invisible holes are covered with coir fiber plugs. The places of plugs are marked with visible markings with coir twine loop for easy removal. One end of the square coir super log comes with a pouch from the netting to facilitate sound connection between two logs.
