On the other hand you may experience less issues with humidity, especially if your greenhouse floor is covered with paving slabs. Growing in containers also allows the grower more control over nutrient addition.

In a heated greenhouse the seeds can be germinated and planted around March/April, depending on your local weather conditions. This allows an earlier start than is usually possible outdoors. That’s because the greenhouse offers extra protection from the worst of the early season weather.

Greenhouse overheating. Protecting your plants from extreme summer heat

If you get a greenhouse it pays to think carefully about the location. When it comes to security, always think about a location which makes it difficult for neighbours or the public to see/smell your crop. Also consider your local climate. If you are living in a cool climate it pays to locate the greenhouse where it will receive maximum sunlight for as much of the day as possible. If you live in a hot, desert climate you may want to consider locating the greenhouse under some trees which will shade the greenhouse during the hottest hours of the day in mid-summer. Mediterranean greenhouse growers may wish to place their greenhouse in a cooler, northern part of the garden where some shade may be present. Remember that when temperatures reach 40-45ºC the temperatures become damaging.

Ensuring air movement and regular air changes in your greenhouse is important. Some of the techniques used to keep your greenhouse cool will also reduce humidity. Having adjustable roof vents which can open to release humid air is a great help. Having a through-draft thanks to an open greenhouse door is also a good idea.

You can start with marijuana seeds or clones. Whichever you choose, pick the highest-quality stock you can find. This is no place to pinch pennies. Dealing with a reputable company and getting top-notch genetics will help ensure a bountiful crop that’s high in quality as well as quantity.

Plants will usually begin to flower around the summer solstice, the longest day of the year. Flowering will continue for two or three months till they are ready for harvest.

Whether you’re raising cannabis as a cash crop or just for personal use, you have many options for where and how you grow it. It’s possible to grow pot outdoors, indoors or in a greenhouse or high tunnel.

Growing Marijuana in a High Tunnel or Greenhouse

You will want to be sure to give your cannabis plants adequate amounts of water and fertilizer to ensure steady, strong growth throughout the season. A drip irrigation system can supply these essentials reliably and economically. DripWorks.com has an entire section on the best irrigation products to grow cannabis.

Once you have purchased or built your greenhouse or high tunnel, you’ll need to decide where to put it. Generally, a spot with southern exposure is best. This will provide a steady source of growth-inducing sunlight to your plants. You may also want to locate your high tunnel or greenhouse in an inconspicuous spot to deter thieves, vandals and other troublemakers.

If you live in a climate prone to more clouds than sun, you may want to consider investing in auto-flowering seeds. These will flower in a set time rather than depending on sunlight to spark flowering.

Greenhouse vs. High Tunnel

Like greenhouses, high tunnels shelter plants from the elements. They differ from greenhouses, however, in that they are more passive. Generally, greenhouses provide heat and ventilation through electrical systems, while high tunnels rely on passive ventilation systems for moving air and on the sun for providing warmth.

Of course, that means high tunnels cost significantly less than greenhouses. How much less depends on the options you are looking for. A variety of high tunnel greenhouse kits and traditional greenhouse kits are available for purchase. If you are handy and looking to save, you can also assemble your own high tunnel or greenhouse with some basic materials.
