Indoor cultivation

You can use Suzy’s premium cannabis seeds for both outdoor and indoor cultivation. However, decide if you want to cultivate inside or outside before you buy the seeds. Some types are appropriate for indoor cultivation while others on the contrary grow better outside. Indoor cultivation has both advantages and disadvantages.

Advantages of growing cannabis seeds indoor:

  1. The cannabis remains clean and free from parasites, germs and fungus traces.
  2. Environmental factors can be controlled and you manage the growing circumstances yourself.
  3. You can cultivate cannabis the whole year, with possible multiple harvests a year.

Disadvantages of growing cannabis seeds indoor:

  1. You have to possess good technical knowledge. You have to know for instance how to set up the installation and how to maintain it.
  2. Purchase costs of the installation and other requirements can be demanding.

What do you have to keep in mind with indoor cultivation?

The most important factors for the growth of your cannabis plants are: air, light and soil.


An appropriate cultivation room remains reasonably cool during the summer. Ventilation is top priority when setting up an appropriate cultivation room, which is clean and bug free. It’s important that you purchase a good suction pump and a fan, so that fresh air can come in and old air can be directly pumped outside. That way you can control the oxygen content and the humidity level of the air.


It is important that the cultivation room can be made completely dark. The duration of the night is very important for the cannabis plants so make sure that you use a timer to create a regular cycle. There are different wattage lamps to cultivate cannabis. You can choose from 400 watt, 600 watt or 1000 watt. High pressure sodium lamps are ideal for indoor cultivation (gaseous discharge lamps). The lamps should be replaced on a yearly basis in order to create optimal light.


The bigger the pot, the easier it is for the cannabis plant to grow. When a cannabis plant has filled the pot with roots, it needs to be repotted to a bigger one so that the roots can grow again. Make sure you use clean soil with a good texture, which determines the capacity to hold and drain away water. You also have to use the right amount of nutrients (nitrogen, potassium, phosphorus, et cetera). The PH value needs to be about 6.5. This determines the absorption of nutrients of the roots. Appropriate soil is available in grow shops. For more information on how to prepare your growing room check our growers guide.

Suzy’s Tip: Never use soil for outside for indoor cultivation. You could introduce harmful parasites and insects.

Some of the cannabis strains are better to grow indoors, depending of the area and the climate. Here we selected the best cannabis seeds for indoor growing.

How Hemp Is Moving Oregon Marijuana To An Indoor Grow Crop

Demand for hemp drives Oregon Cannabis Farmers Indoors

In a post-Farm Bill world, Oregon is proving to be an interesting test case of the agricultural and economic reality of legal hemp and marijuana coexisting en masse.

In short, success is not without its complications.

Oregon became one of the first states to legalize recreational marijuana when voters passed the law through a ballot measure in 2014. To combat the cannabis black market, Oregon regulators made it incredibly easy for anyone—including former black market growers—to get a license to grow. Despite the legislature’s best intentions, this led to unintended consequences.

Last year, cannabis cultivators in Oregon grew way more pot than demand required. In May 2018, Oregon had over one million pounds of flower in the state’s inventory—or, a quarter pound of weed for every resident in the state. The massive overproduction has caused the price of a gram of weed to drop by 50%. On the other hand, the price drops have spurred a huge increase in sales and sales tax revenue.

In order to fight the glut of legal weed from becoming black market weed in other states, Oregon marijuana growers must notify officials of their harvests. The argument for this added regulation is that it will prevent illegal interstate trafficking, while cannabis growers argue it creates more bureaucracy for the struggling growers. While it may help quell the interstate black market, it doesn’t help address the issue of crashing prices due to overproduction.

To address this issue, marijuana growers are looking to diversify. Even prior to the signing of the 2018 Farm Bill in December, Oregon growers pivoted to industrial hemp to make up for revenue shortfalls. In Oregon, hemp has some major advantages over marijuana right now. According to Marijuana Business Daily:

  • Most marijuana grow operations are limited to less than an acre, while industrial hemp operations can be several acres. With the current oversaturated marijuana market and the high demand for hemp-derived CBD, there’s much more money in hemp than marijuana.
  • Hemp is easier and cheaper to grow and has fewer regulatory hurdles and costs.
  • With federal legalization, hemp is a national and international market; Oregon marijuana often must stay in the state.

While there are many advantages to growing hemp and marijuana together in order to diversify, many growers don’t have the knowledge or skills to add a 40-acre hemp operation to their one-acre marijuana operation. This is the wrinkle that has the potential to radically alter the Oregon cannabis industry.

The science of mixing hemp and marijuana

With the 2018 Farm Bill making it legal for farmers to get loans from banks and crop insurance for hemp crops, growers have even more incentive to make the switch.

According to The Oregonian, since 2015 the number of licensed hemp growers has climbed from 13 to 584, while hemp acreage has exploded from nothing to 11,000 acres. From an economic perspective, there’s no reason for farmers to stop planting acres of hemp alongside their marijuana. With estimates from Grand View Research placing the industrial hemp market over $10 billion by 2025 and the Brightfield Group suggesting the CBD market alone will climb to $22 billion by 2022, hemp has a much higher growth potential for Oregon farmers.

The booming hemp and marijuana market may make economic sense together, but—scientifically speaking—it may be more difficult for them to get along.

The issue comes down to cross-pollination. Hemp, like some strains of marijuana, belongs to the Cannabis sativa family. However, as Aaron Cadena explains in this useful primer on the subject, hemp and marijuana have crucial chemical and structural differences. Marijuana provides high levels of the psychoactive chemical THC, but hemp lacks high quantities of the chemical, making it an ideal source for CBD oil.

One of the common misconceptions is that marijuana and hemp are the female and male versions of the cannabis plant, respectively. While this isn’t true, the issue of sex is critical for growers. Marijuana growers typically avoid male plants. Female plants that are unpollinated will provide high-quality, seedless flower buds. Growers achieve sexual homogeneity through careful cultivation and cloning. Hemp growers are less careful, though, and may even wish to have both male and female versions for various uses, depending on whether they’re looking for high levels of CBD or fibers, for example.

Since the first days of recreational legalization in Oregon, farmers have been worried about cross-pollination between carefully cultivated strains of female marijuana and male hemp plants. According to the Willamette Week in 2016, “many outdoor marijuana farmers were worried hemp pollen would drift downwind and contaminate the genes of their prized psychoactive stocks, lowering their THC content. This was a particular worry because according to the regulations at that time, all hemp had to be grown from seed rather than female hemp clones that wouldn’t pollinate. In Colorado, hemp farmers have even accused recreational farmers of setting fire to their crops.”

The animosity between hemp and marijuana growers is real because the potential for disaster is so real. Cross-pollination can encourage seed growth and cause THC levels to plunge in marijuana. Research has found that cannabis pollen can travel between 3 and 30 miles. In a state blanketed by cannabis growth, the prospect of cross-pollination between hemp and marijuana is almost a guarantee.

The combination of crashing marijuana prices with the legalization of industrial hemp may bring the issue to the fore in Oregon this year. California and Colorado will also likely face the same issue.

Marijuana growers must pivot to indoor grows

It is unlikely, at this point, that the state will pull the plug on industrial hemp. And, since industrial hemp requires so much more acreage, marijuana growers are left with one option: moving indoors. “Marijuana and industrial hemp don’t belong in cultivation together,” explains Anndrea Hermann, international hemp expert. “There’s a risk for marijuana growers when industrial hemp is grown with male plants present.”

However, many outdoor growers are reluctant to move indoors because of the high costs associated with building new structures and providing pollen-reducing levels of filtration. According to The Seattle Times, “Sixty-five percent of Oregon’s outdoor growing sites for recreational-use marijuana — 258 farms — are concentrated in two rural counties.” The high concentration of outdoor grows only increases the chances for cross-pollination.

If authorities wanted to send cannabis growers indoors, they should encourage hemp farms. The cross pollination of hemp and cannabis ruins the potency of the cannabis. Guerilla growers have had to deal with ditch weed ruining crops for decades.

Whether co-existent hemp and marijuana becomes a state-regulated issue or marijuana growers make the move indoors on their own as THC-yields fall and seed-laden flowers start to bloom. As marijuana growers bear the brunt of the costs of this issue, it may have the effect of bringing prices back up as they pass the cost of building indoor grow operations to the consumer. Plus, more growers may ultimately switch to solely outdoor hemp cultivation to avoid the issue altogether, which will reduce the potential for overproduction in the future.

The short term looks painful for marijuana growers in Oregon, but a détente between marijuana and hemp growers may ensure the future of the state’s cannabis industry.
