Monticello Greenhouse 8x20 - Growers Package

Monticello LogoCannabis production continues to earn a legal status globally. Cannabis growers are also increasing and are learning about greenhouse production techniques. The Monticello Growers Edition Greenhouse is specifically designed to provide privacy, secured setting, and an excellent indoor environment. Proudly MADE IN THE USA.

Your plants will also need fresh air for photosynthesis and prevent diseases. The commercial electric exhaust fan system with built-in louvers and the commercial thermostat will help control the temperature inside your Monticello Greenhouse.

Monticello Growers Edition Greenhouse 8ft x 20ft is the best startup greenhouse for cannabis growing. It is designed for crops that require a lot of light in a private and secure setting. Let us cover specifically what comes with the best small greenhouse.

Comparison of 8mm clear Polycarbonate panels next to light diffusing panels from the Monticello Growers Edition, with 3-inch and 0 distance

The Growers Edition Greenhouse comes standard with the light-diffusing 8mm twin-wall roof and wall panels…

  1. These panels create a more even light flow into the greenhouse creating a glow instead of a light beam effect for a more even light distribution for a longer period of time.
  2. The light-diffusing panels also offer a higher level of privacy, just eight inches away and you cannot see into the greenhouse.
  3. The twin-wall Polycarbonate acts as a double-pane window keeping the cooler air in during warm months and insulating the greenhouse from cold air in the wintertime.
  4. This not only makes the Monticello more efficient to grow in for a longer period of time than other greenhouses but it also adds to the efficiency of growing, cutting down electric bills for those who choose to grow year-round.

FAQs

Is the frame anodized?

Yes & No. The aluminum frame is anodized. However, the black frame is electrostatically painted.

Is the black paint powdercoated?

No, the black paint is electrostatically applied which is stronger than powder coating. It is very difficult to scratch and should not fade dramatically. Riverstone Industries guarantees it for 10 years.

Is the aluminum frame cooler than the black frame?

Yes, the aluminum frame is on average about 7 degrees cooler than the black.

Can the Monticello be attached to a concrete pad? If so what are the dimensions needed for the concrete pad?

Yes, you can use a concrete pad. Riverstone Industries recommends that you add 3 – 4 inchs to the pad on all sides.

For Example: The 8ft x 8ft (exact size of 8.1ft x 8.1ft) would need a concrete pad of 8.4ft x 8.4ft.

Note: Riverstone Industries does not provide concrete screws, you will need to buy these from your local hardware store.

What tools do I need for the assembly or is everything included?

Not everything is included. Here is a list of tools you will need and items included:

  • Work gloves
  • Safety goggles
  • Spirit level
  • Tape measure
  • Step ladder
  • Clear silicone caulk tube
  • 23 1/8 inch spacer (included)
  • 7/16 wrench (included)
  • Philips screwdriver (included)
  • Flat screwdriver (included)
  • 5-foot bungee cord (included)

Can I extend the Monticello Greenhouse later?

Yes, it is expandable in 4ft increments.

We live in a seismically active area south of San Francisco. I’d like to install the greenhouse on a hill. Is this the best greenhouse for my conditions?

Monticellos are very sturdy greenhouses. However, the greenhouses are not tested for earthquakes. What we can suggest for you to do is to check the bolts and make sure everything is tightened after an earthquake or from time to time. The panels won’t pop out unless the frame is loose. The channels are made to fit the Polycarbonate snugly.

What does the ventilation fan do versus the auto openers in the roof?

Automatic vent openers are self-contained units which require no electricity. It is a temperature-sensitive device that automatically opens and closes a roof vent. So, they release heat and they basically require wind to make the air flow through the greenhouse.

The powered ventilation fan gives you more control. It removes excess heat by creating air movement throughout the greenhouse. However, it’s just a fan, not an AC unit. So, on very hot days, you’ll still experience higher temperatures inside your greenhouse.

Do the doors swing out or slide to the side? What is the door width?

It’s a hinged door so it swings. The door opening is 4ft x 6ft.

Where does it ship from?

Georgia, USA
