4 mil Convection Tubing is ideal for cooling greenhouses, uniform dispersion of heat from a force hot-air furnace, for improved mixing of air in greenhouses, and so much more. Ken-Bar's poly convection tubing is available in 4 & 6 mil. The polyethylene is clear and is protected with a strong ultraviolet inhibitor. The formulation of the plastic is designed for maximum light penetration and for durability in a greenhouse environment.
Ken-Bar provides proper diameter holes and spacing that conform to the fan manufacturer's specifications. A properly designed tube will make full use of the fan's output by distributing air evenly down the length of the greenhouse. Punch position can be varied as shown below to provide the best possible airflow for each situation.
Guarantee - Each tube is guaranteed to support the cubic feet/minute output of the fan. If there is a problem, the tubing will be replaced immediately. The 4-mil tubing is guaranteed for 1 year.
Seem to be holding up well so far, I bought 30 and filled them all up and have moved them several times with no issues. Will be buying more.
The product came quickly, the trays work great together and there have been no issues.
Great product for the price. Good quality and will last a few years. The best place I've found to buy pots.
This test was easy and convenient. The results came back quickly. I found out I was very low in nitrogen. Glad I found that out before I planted tomatoes and peppers.
My neighbor saw how great my fabric was instead of the stuff from big box stores. He wanted me to order for him and that is this order. He is excited to get it in.
Work great for what we needed. Nice quality trays!
Just what I would expect for cardboard beer boxes. Get the job done. Will buy again.
We've used these 6" pots two years to pot bare=root seedlings to give to school children. They work great for that purpose. Easy to transport. Allow seedlings to bud out before taking to schools. Easy to explain to kids how to plant the trees/shrubs without having to remove them from the pots. Smaller pots don't provide enough room inside to contain the roots of the seedlings.
These work GREAT in holding down your weed fabric! Easy to install and I’ve even used these in the garden to secure plant trellis strings.
Have ordered custom shade cloth from Growers Solution in the past and have been satisfied both times. I would order again.
