I make 3 bag sizes. The 1/8 of a gallon which I have been selling for the last 6 years, (6.5″X2″x1.75″). When open they are about 5.5 inches tall., the half a gallon (4″X4″x9″) and the gallon (5″X5″x11″). All bags are made out of a black plastic called HDPE and are 3 mills thick. The smaller bags are only 2 mils thick. This makes them very strong and durable They are reusable. They are also UV protected. I designed the small bags with the idea of planting trees. I have a few thousand trees planted in them, some, the slow movers, have been in the same bag for 3+ years. All the bags have a vent hole in the bottom.
The half gallon bags are 4X4X9 inches. Fill them to within an inch of the rim. These were designed for Perennials. The 1 gallon bags are 5x5x11 inches I use them for trees only, in fact I have poplars in them.
I am sending free samples of these bags, just send me an email with your name and address, and the word “bag” in the subject line. I will ship you all 3 sizes by return mail.
The White Coroplast trays shown above fit 4 half gallon bags or 16 1/8 gallon bags and are available below.
The trays are shipped to you flat, along with 24 male and 24 female fasteners. To assemble, first bend the large flap towards the inside (follow the creases) and then the larger flap over it. See photos. Insert a fastener in the hole in one side of the flaps and the opposite fastener in the other side and press them together. Now do the other 3 corners the same way. Reinforce the fasteners by pressing them together with a pair of pliers to just tap them with a hammer.
