The Grow4it System


"The LED lights working in conjunction with the seed trays/root spas provide an extraordinary approach to growing abundant amounts of produce in a relatively compact space and in a reduced time period. We really love our new Grow4It system and would recommend it to anyone else that takes their growing seriously!"

What is Solexx Covering?
The twin-wall plastic Solexx greenhouse covering is made of high-density polyethylene extruded with the structure of corrugated cardboard but with the enduring qualities of plastic. The covering is insulated and can withstand virtually any weather condition.

The greenhouse covering is not clear. Isn't it too dark inside to promote growth?
No, actually Solexx greenhouse covering transmits 70-75 percent of the available light. Most plants only need 40 percent light to grow, but 70-75 percent available light is the optimal growing range. Even on cloudy or rainy days there is usually enough light in the greenhouse for growth. The Solexx greenhouse panels diffuse the light evenly throughout the greenhouse eliminating and shadows and hot spots to prevent plant sunburn in your greenhouse.

Does the greenhouse covering break down in the sun?
Solexx greenhouse covering has a UV additive added throughout the material during the extrusion process. Solexx is covered by an 8-year limited warranty against ultraviolet breakdown. Solexx greenhouses have been in the field for over 20 years and there has been minimal UV breakdown. All plastics do eventually break down when exposed to direct sunlight for extended periods of time, however, the greenhouse panels are easy and inexpensive to replace. In high sunlight areas, the life of the greenhouse panels can be extended by using a shade cloth and/ or placing the greenhouse structure in a partially shaded area.

Will the greenhouse covering discolor?
No. The greenhouse covering will not yellow, mold or mildew. The material will not scratch so you will not have the "cloudy" appearance as with other types of greenhouse paneling.

How do I clean Solexx greenhouse paneling?
Solexx can be rinsed or wiped clean without worry of scratching. The glazing is impervious to chemicals, so you can safely wash it with a mild detergent.

What type of Solexx greenhouse glazing would be best in my area?
Solexx greenhouses are available with either 3.5mm (Solexx XP) or 5mm (Solexx PRO) thicknesses. The 3.5mm greenhouse panels are recommended in most areas as they provide more light transmission. The 5mm greenhouse panels are used in very cold climates (for added insulation) and at high altitudes.

What makes Solexx Greenhouses different from the other greenhouse on the market?
One of the most unique features of Solexx greenhouses is the greenhouse covering. The Solexx greenhouse provides highly diffused light (the best type of light) to your plants so they will have optimal growth.  University testing has shown that plants grow best under diffused light.  We also can deliver the greenhouse to our customer's door by UPS. Another feature that makes Solexx different is the built-in bench frames. With almost all other greenhouse kits, benches are a large additional expense. Strong full-length hanging rods are another great feature.

How long will it take to assemble the greenhouse?
The 8' units can usually be assembled in a weekend or two using common household tools. Much of the greenhouse can be put together with one person. The framing is precut and color-coded to make assembly easy with just a few household tools.

How do I prepare my greenhouse site?
You can place your greenhouse on your lawn, over bare ground, on a gravel base, over a wood deck, on a concrete slab, or a brick patio.  Very little site preparation is required for your Solexx Greenhouse. Simply find an area in your yard that gets plenty of sunlight (southern exposure is best) and level the ground.  Lay down greenhouse flooring over the surface to prevent weeds in your greenhouse while allowing necessary drainage.  Pour about 3" of compacted 1/4" gravel base on top for added drainage and a sturdier floor.  And of course, don't forget to tie down your greenhouse once it's in place!

How do I secure my greenhouse?
The most important accessory is a tie down kit. The greenhouses are lightweight and must be tied down. We have a tie down kit available, but you can use any method that will securely anchor the frame. Some methods include tying the frame to cement anchors or screwing brackets over the frame and into a deck.

What tools will I need to assemble my greenhouse?
You will need: a screwdriver, variable speed drill, sharp knife or utility knife, tape measure, step ladder, GE Silicon-2 caulk, Caulking gun, clear PVC glue, and level.

Will the greenhouse handle high winds?
As long as the greenhouse is firmly anchored you should not have problems with wind. The combination of a strong frame and flexible paneling works very well in adverse conditions. Many of our customers live on the coast and frequently experience winds of 70 mph. One customer in New Jersey has a Solexx greenhouse that had no damage from the impacting tree branches from a hurricane.

Will the greenhouses withstand heavy snow loads?
The greenhouses do well in snow. The greenhouse paneling is slippery so snow frequently just slides off the structure, and low temperatures will not harm the greenhouse plastic. If there is a snow build-up, the greenhouse can support several hundred pounds of pressure. Solexx greenhouses are undamaged after being covered in several feet of snow and exposed to subzero temperatures for most of the winter. See a video of the greenhouse snow load!

Is the greenhouse portable and/ or can it be disassembled?
The greenhouse is portable; it is easy to put onto a trailer for transport or move from one area of your yard to another for the best light. It is not suggested that the greenhouse be disassembled - the panels are attached to the frame with screws and once the screws are removed, realigning the panels to the pipe would be very difficult.  There is also gluing involved in construction that cannot be disassembled.

How well does Solexx Insulate? What is the R-Value (R-Factor)?

Compare the insulation quality of Solexx to other greenhouse coverings on the market...

Greenhouse Covering R-Value U-Value
5mm Solexx Panels 2.30 0.43
3.5mm Solexx Panels 2.10 0.48
8mm Triple Wall Polycarbonate 2.00 0.50
Double Pane Storm Windows 2.00 0.50
10mm Double Wall Polycarbonate 1.89 0.53
8mm Double Wall Polycarbonate 1.60 0.63
6mm Double Wall Polycarbonate 1.54 0.65
4mm Double Wall Polycarbonate 1.43 0.70
Single Pane Glass, 3mm 0.95 1.05
Poly Film 0.83 1.20

R-Value - the measurement of ‘insulating ability’ of the material. The higher the R-Value number the greater the insulation value.
U-Value - the measurement of ‘heat loss’ through the material. The lower the U-Value the less heat is escaping.

Are the bench frames removable?
The greenhouse bench frames are part of the structure of the greenhouse and not removable. They give you 76-sq. ft. or more of growing area and are an essential part of the Grow4it system to give you plenty of room to grow food.
