Our greenhouses are made using aluminum square tubing; therefore, no rust!! Most other greenhouse manufacturers use steel round tubing for their framework. Square tubing is 60% stronger than round tubing of the same gauge, size, and material.

The trend today is the more compact McInnis style greenhouse and not the older style 30 ft. wide greenhouse. A McInnis greenhouse is easier to heat and cool than the larger greenhouses covered with polyethylene film. Many schools buy two units and teach one aspect of horticulture in one greenhouse and a different program in the other. With two McInnis greenhouses you can offer different horticulture programs to various classes or age groups. This is not possible if you have one large greenhouse as all the plants are treated the same. Most find it is cheaper to buy several McInnis greenhouses than one big greenhouse. With a large greenhouse you still have the expense of heating and cooling the total greenhouse even though you may only have a few plants.
