Grubba Grow House Review – Commercial Marijuana Production

Jumpstart your Commercial Cannabis Operation with a Grubba Grow House

- Pounds of Marijuana -

As the wave of marijuana legalization sweeps the nation, many growers are happily making the switch from furtive guerrilla grows to respectable commercial operations. But even in states like Colorado where marijuana is now fully legalized starting up a new business as a legal commercial grower is not easy. There are business plans to write, licenses to obtain and zoning laws to contend with. Even in many commercial and industrial areas it can be difficult to get approval to grow cannabis.Commercial Cannabis Grow IndoorsOnce you overcome the legal hurdles, you still have to create a suitable space to cultivate your plants. For most commercial growers, outdoor gardens and even greenhouses are generally not an option, as zoning laws typically require the plants to be grown within an enclosed building. Converting an existing space into a suitable grow room is an expensive and tedious process. You need to consider ventilation, lighting, water, and CO2 supply, not to mention heating or cooling depending on your climate and the logistics of arranging pots or installing a hydroponic system.

Get Ready for your Grubba Grow to Arrive

There are just a couple of things you will need to make your property ready to receive your grow house:
  • 1. Electricity
  • Your grow house will need a power source. Grubba Grow gives you a couple of options which allow you to increase your energy efficiency:
    • a. 230V Single Phase
    • This option is up to 50% more efficient than using standard 115V Single Phase.
    • b. 230V Three Phase
    • The three phase choice is 40% more efficient than the 230V Single Phase, making it 70% more efficient than the standard 115V Single Phase.
  • 2. Water
  • You will need to connect your Grubba Grow to a water source. It comes with a standard ¾” female threaded garden hose connector. Make sure your system can supply 40-60 psi to this connection. Once you’re hooked up just adjust the grow controls to set your irrigation cycles.
  • 3. Gas
  • The CO2 system can be run on either propane or natural gas. You will need to specify your choice when you order. If you change your mind at a later date there are kits available to change the necessary components of the gas delivery system.

Getting Started...

When your Grubba Grow arrives you will have to do some minimal assembly. Pieces such as the rain caps, HVAC unit and top duct will need to be installed. If you are wary of attempting this yourself, Grubba will send a technician to complete the installation on site.
