How to Grow Weed in a Greenhouse

Growing your weed in a greenhouse can be fun. Here’s a simple guide to get you started, including the basics, costs, and the best strains to grow.

What is a Greenhouse?

A greenhouse is a structure with a durable frame and a transparent cover, usually made of plastic. It lets you grow plants by controlling the environment. Greenhouses protect plants from the weather, increase carbon dioxide levels, and maintain consistent temperatures. Do check out best edibles toronto

Benefits of Growing Weed in a Greenhouse

Growing weed in a greenhouse combines the benefits of outdoor and indoor growing. It offers protection from natural elements, better control over the environment, and often results in faster growth and better yields.

What to Grow in a Greenhouse

Greenhouses are flexible and can grow various plants, including flowers, vegetables, and cannabis. They are perfect for starting plants that will eventually be moved outdoors or for growing plants to full maturity. Cannabis grows in the controlled environment of a greenhouse, benefiting from the sun’s power and protection from the elements.

How Many Cannabis Plants Can You Grow?

The number of cannabis plants you can grow depends on your state’s laws. For example, in Oregon, you can grow up to four recreational plants per household. Medical marijuana cardholders can grow more. Ensure you have enough space for your plants to grow. Each mature cannabis plant can take up an 8×8 foot area.

Growing Weed Year-Round

Growing weed year-round in a greenhouse depends on your climate and setup. In colder areas, you might need heaters and supplemental lighting for shorter days. Choose an A-frame or gothic-style structure to withstand heavy snow.

Starting Your Greenhouse Grow

Here’s what you’ll need to start growing weed in a greenhouse:

Greenhouse framing materials

Durable covering

Fans and ventilation

Pots (like Smart pots)

Soil or growing medium

High-quality nutrients

Water supply

pH meters and adjusters

Thermostat

Trellis materials

A light deprivation system (light dep) can help you grow more than one crop per year by controlling the light your plants receive.

Costs

The cost of starting a greenhouse varies. A basic DIY greenhouse with aluminium framing and polyethene plastic costs about ₹1,200-1,600 per square foot. A custom greenhouse with advanced features like an automated light dep system costs around ₹2,800-3,200 per square foot. A budget-friendly 1,000-square-foot greenhouse with light depth can be built for about ₹8,00,000.

Pros and Cons

Pros:

Protection from animals and weather

Controlled microclimate for ideal growing conditions

Consistent annual harvests

Cheaper than indoor growing

Cons:

High energy costs for heating and lighting in winter

Potential odour issues for neighbours

Takes up significant space

Can be expensive to build

Best Strains for a Greenhouse

The best cannabis strains for greenhouse growing are auto-flowering and photoperiod feminized strains. Autoflowering strains, like Purple Punch and Northern Lights, switch from the vegetative to the flowering stage on their own, making them easy to grow. Photoperiod feminized strains, such as Blue Dream and Sour Diesel, need a light dep system to control their flowering cycle.
