Soil: First and foremost, invest in top-quality soil as this will impact the entire growing process. Pick a nutrient-packed soil that contains organic substances like compost and worm castings. Pay attention to the pH levels of the soil as well — aim for a range of 5.8 to 6.3. Other qualities to look for in soil include good drainage ability, high oxygen levels, and effective water retention. You could also make your own super soil.
Free-standing greenhouses: From a simple walk-in greenhouse with room for a couple of plants to the massive connected behemoths set up by commercial growers, free-standing greenhouses are what most people picture when they think of a greenhouse. They are apex shaped, like a house, and consist of metal or wood frames and glass, fiberglass, or plastic panels. Many have roof and/or side panels that open to allow for ventilation. This may be the most expensive option, but it also has the most room for plants while still allowing for location flexibility so growers can move it to best capture the sunlight. Inexpensive free-standing models start at less than $100 but they may not be very durable. Sturdier models cost closer to $1,000 and prices go up from there.
If DIY is not your style, think about your budget and how many plants you’ll want to grow then decide how much space you’ll need for plants, climate control, and the rest of your greenhouse setup. Armed with that information, consider the options below.
Cannabis cultivation can take place indoors, outdoors, or in a combination of these two places: the greenhouse. A greenhouse can be as small as a tool shed or as large as an industrial building. If you have enough space to accommodate even a small greenhouse, this option may propel your cannabis cultivation to the next level.
Polytunnel: These elongated, dome-topped greenhouses have an aluminum frame and a covering of polythene. They are usually big enough to walk into but not as sturdy as actual greenhouses. Accordingly, polytunnels are on the lower end of the price range, starting at around $160. These can be durable but do need some maintenance, especially replacement of the cover every three to five years.
A marijuana greenhouse also puts you in control of two primary factors in successfully growing marijuana plants.
In this guide, you’ll learn why growing marijuana in a greenhouse can be effective and how to get started.
Buying a cannabis greenhouse
Think about the storage space you’ll need for your greenhouse setup, including supplemental lighting and nutritional blends. You’ll also need an easily accessible place to store water and soil, so that the greenhouse is a one-stop location for all your cannabis cultivation items.
Climate: In addition to protection from rain and wind, marijuana greenhouses can contain climate control equipment like dehumidifiers, exhaust fans, and heating and cooling systems. With the help of these tools, greenhouses can extend the growing season and allow for year-round cultivation.
Many folks in northern latitudes start their seeds indoors in April under grow lights and transfer them to a greenhouse in May. Your own schedule will depend on your climate and growing season, of course.
Generally, two basic options are available for growing your pot plants. You can grow each marijuana plant separately in its own container, or you can put the plants in the ground. Using containers will make the plants easier to work with and to move if you want to transplant them.
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.
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 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.
To help you get on your way, DripWorks is happy to provide you some basic tips on how to grow marijuana in a greenhouse or high tunnel.
In many ways, growing marijuana in a greenhouse or high tunnel offers the best option. An outdoor marijuana greenhouse or high tunnel lets you take advantage of some of nature’s benefits, like abundant sun, without having to kneel to nature’s bad side, like frost, storms and deer, rabbits and other pests.
Greenhouse vs. High Tunnel
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.
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.
