There’s more to marijuana growing in Washington.

Here are more details:

Growing Medical Weed in a Recreational State

Growing Medical Weed in a Recreational State like washington
  • Growing is Medical-Use Only. Washington is a recreational state, but it does not allow growing for recreational purposes. Home growers must have a recommendation from a doctor.
  • Growers need to be 21. Washington restricts growing to medical patients, but it does not restrict the age of patients. Growers must be 21 and may be the designated grower for an underage. Dispensaries that grow for patients must employ growers that are 21 and up.
  • Grow up to 4 (or 15) plants. With a recommendation from a doctor, a patient can grow up to four plants. With registration, a patient can grow fifteen plants. If multiple patients reside in one house, the limit is fifteen plants. Breaking this rule will cause more hassle than anything else. You will be arrested, but you can argue it in court if a doctor can explain why you need so much. The worst part is, if you grow too many (or grow without a recommendation), police can keep your plants, even if you win in court.

    Rules on Cooperative Gardens and Registering as a Patient

    Medical marijuana - Rules on Cooperative Gardens and Registering as a Patient
    • Cooperative gardens are allowed. Up to four patients can grow together. Up to sixty plants can be grown in a cooperative. The harvest can be as much as 72 ounces. Cooperatives are basically gardening clubs for patients. In them, patients work together to grow a variety of strains. All patients must be 21 or older and must register with the state. A cooperative garden cannot be less than 1 mile from a retail location.
    • Register if you want to. Registering as a patient will earn you a recognition card that can be displayed as proof of permission to grow. In addition to having a grower’s permission slip, you can also grow more plants than those without it. A recognition card will also prevent arrest, as long as you do not have more than 15 plants.

    Growing without registration is allowed but risky. If you do not have a recognition card, you could be arrested, but you may not be guilty if you produce a medical recommendation.  If you don’t plan to register, it’s best to keep your growing stealth.

    Washington laws favor retail marijuana, but some room has been left for patients who prefer to grow their own.  With the closing of medical dispensaries and limitations on where cooperative gardens can exist, growing at home is the best option for Washington patients.

    If you plan to grow in Washington, learning easy indoor growing techniques is the best approach.

    Tips for Growing Weed in Washington

    If you are looking to grow marijuana in Washington- including the cities of Seattle, Vancouver, or Spokane, there are a few ways you can do it legally. This is because Washington, the second state to legalize the sales of recreational marijuana, has also legalized marijuana growing. Here are the two ways to grow marijuana legally in the state of Washington.

    How to grow for yourself in washington

    One way to grow marijuana in Washington State is as a medical marijuana patient. Washington approves the medical use of marijuana for AIDS and cancer-related nausea and vomiting; pain from Hepatitis C; vomiting and nausea due to anorexia; muscles spasms from MS, seizures and epilepsy; blood pressure issues causing glaucoma; pain due to Crohn’s disease and other un-manageable pain.  If a medical provider feels that your condition is manageable by marijuana, you are approved to grow up to 15 plants that yield up to a total of 24 ounces.

    In order to grow marijuana in Washington under this exemption, have a doctor write a recommendation, and register it with the department of health.  If you need a list of doctors that will write a recommendation, try a site like Marijuana Doctors, or ask any other patients who they see.  Keep your registration card with the plants at all times.  If you are not registered but are approached by police, you can try and prove your medical exemption in court.

    Washington residents can also participate in growing co-ops called collective gardens. Collective gardens allow up to ten patients to grow together, sharing the costs and benefits of their plants. Collective gardens also have a total limit of 15 plants.

    Growing marijuana for others in Washington

    It is legal to grow marijuana for others, although in Washington they don’t want you smoking the stuff if you do. You can, however, grow and make some cash.

    To do this, simply grow on behalf of a patient as provider. Providers may grow up to 15 plants for one patient.  As a provider, you can only have one patient at a time and must remain with that patient for at least 15 days. The patient must register their provider in writing with the health department.

    Growers can also grow an unlimited amount commercially as a producer.  There are multiple fees associated with this including application, annual and background check fees. If approved, a license can cost as little as $1300. But if you wanted to commercially grow marijuana in Washington, it can be done. Check this link for more information.

    How much marijuana can you grow in washington

    Whether you grow marijuana in Washington for yourself, or grow it for others, the state does not allow plants to be publicly viewable. So above all, keep your plants out of sight.  There are also limits on how much marijuana any one person can be in possession of, so if you have more than 15 plants, you may want to consider scaling back.

    It’s so easy to grow marijuana in Washington, there’s no reason why you wouldn’t take the simple steps to do it legally. Plus, technically, unlicensed growers can face a fine.  Silly to have that happen when all you have to do is get registered or find someone who is.  So, what are you waiting for?

        1. After I posted the above, I saw the Site had Reduced most words’ first letter to a Small letter, but left some Capitalized which should Not have been capitalized, in a kind of Random way.

        2. Nevada prohibits Users from Growing anywhere near Clark and Washoe counties (Las Vegas and Reno areas) which between them contain most of the state’s population. So Cultivation by users is illegal In NV, Basically. Because they want to allow a gang of economic rapists – I Mean, The legalize Marijuana For Medical and Recreational use Ballot Initiative sponsors – And Their gang of Protectors – I mean, The police and sheriffs of the state – to charge users $400 per ounce for something they could grow in their yards for $2 per ounce. It’s the only time in the history of the world in which legalizing an illegal product resulted in the price rising Substantially. On day one of legal sales in NV, I thought some signs of protest might appear, but the incredibly weak, wimpy Local weed wimps and weaklings – Did i say weak, and wimpy? – instead lined up quietly and obediently and Waited to be raped and fleeced, Starting the day before legal sales began, and have been taking it up the ass most obediently and happily every day since. This site won’t allow me to start any word with a small letter.

        3. Just for the record, Washington state was the first state to have recreational marijuana, not the second.

        4. Considering this article’s “latest update” was Dec 2015. I’d say your comment about researching before the post is a little off

        5. Current laws are this without state registry card four plant with six plants. If you have the need for it and go they the hoops you can grow 15 plants. This is not a everyone thing it is a special case thing so printing if you get a card you get 15 is wrong that is not how this state works at all and you should research your articles better before writing them.

        6. ” A cooperative garden cannot be less than 1 mile from a retail location.” Is that a typo?

        7. “…As a provider, you can only have one patient at a time and must remain with that patient for at least 15 days…” Does this mean the grow has to be at the patient’s home as opposed to growing it on my property and delivering it?

        8. […] Jones told the radio that he had a short talk with Jeff Sessions in Washington before he was appointed Attorney General by the Trump’s administration. He said that during the […]

        9. I mastered more new stuff on this linosg weight issue. A single issue is that good nutrition is highly vital any time dieting. A massive reduction in bad foods, sugary ingredients, fried foods, sweet foods, beef, and white flour products could be necessary. Retaining wastes bloodsuckers, and toxins may prevent aims for fat loss. While certain drugs quickly solve the issue, the horrible side effects are usually not worth it, and they also never provide more than a temporary solution. It is just a known idea that 95% of dietary fads fail. Many thanks sharing your ideas on this weblog.
