COMPLETE FACTORY WARRANTY
Farmers in Humboldt, California are world famous for their innovation and development of organic compost teas. Fresh organic compost tea contains natural biocolonies of beneficial batteria, fungi and protozoa.
Use Boldtbag filters to brew and increase availability of phosphorus and other nutrients and vitamins to meet critical, on-time plant needs. Freshly brewed hydroponic and aeroponic nutrients help defend against disease and help promote vigorous plant growth.

Simply place filter bag into a bucket or barrel. Measure prescribed amount of dry bat guano and other necessary nutrients. Fill with water and steep. Raise the bag up, allowing all of the custom made compost to drain out of the bag and letting the custom made organic compost tea drain back into the bucket or barrel.
STRENGTH THEY’RE BOLTED
Boldtbags are industrial strength filter bags. They are sewn with extra reinforced double stitching and use military grade nylon thread, and heat-fused nylon lined with FDA compliant resins. This water tight lining ensures no absorption of bag contents into the fabric and produces a higher yield. It also allows for bucketless use in suspension systems.
They are available in 3 bag, 4 bag, and 8 bag kits to provide you with the best range of quality filtration solutions.
The filter screens are Swiss grade quality, pressure rated and measured to the absolute microns and heat stamped to assure microns accuracy and to prevent pore-size fluctuation.

The reinforced rivet construction makes Boldtbags extremely strong. The patented rivet construction ensures that these filter bags won’t burst. The rivets and eyelets are durable marine grade, nickel-plated brass and will not rust.
Supporting heavier loads is easy with a hook and pulley system that is easily assembled using the grommets.
FULL WARRANTY against any rip, tear, or manufacturers defect. Just clean and return for a free replacement.
Made in Northern California, where people expect only the best!
