Marijuana plants must be kept in an enclosed, locked area that can’t be viewed openly. This means the plants can’t be outside.
The laws are different for medical marijuana consumers.
Coloradans can grow marijuana in their homes for personal use.
Up to six plants are allowed per Colorado resident over age 21, with as many as three plants flowering at one time.
At homes with residents under 21, any marijuana grow area must be enclosed and locked in a separate space that minors can’t access.
Don’t forget that counties and municipalities can pass stricter laws. For example, Denver limits a home grow to 12 plants, even if there are three or more adults over age 21 in the residence. Be sure to check your local laws for specific details.
At homes without residents under 21, extra precautions must be taken to make sure any visiting youth don’t have access to marijuana plants.
Archambault: Well, the plants are still going to release that telltale aroma. Hydroponic stores sell odor mitigation systems. Carbon filters are the most effective. If your grow system is in a basement room that nobody uses, maybe they won’t notice.
Q: That sounds like a ton of work. Is it easier to start with cuttings?
Holmes: In indoor gardens, you mimic the spring and summer growing period with a light that’s on the white/blue spectrum. In the vegging state, you’re encouraging the plant to produce leaves, with a goal of growing the plant to half the size you want it to be when you harvest it. The rule of thumb is giving the plant 18 hours of light in the vegging [short for vegetative growth] stage. So if you want a 3-foot-tall plant at the harvest stage, you want to veg it until the plant is a foot and a half tall.
Q: How much space would a $500 dirt set-up require?
Archambault: Start from seeds. I’ve never met anyone who bought a clone from a dispensary that wasn’t infested with spider mites or powdery mildew. It’s an indoor growing issue. The worst thing you can do is buy a plant that has a lot of insects.
Holmes: For a very basic set-up, around $500. Figure $20 for the containers, $40 or so for the soil, another $40 for the fertilizer and nutrients, $300 for a decent grow light, another $100 for a vegging bulb and a flowering bulb. Figure on spending $5 to $10 per seed, but prices vary widely. Some seeds cost $1,000 apiece.
No more than three of your plants can be in the flowering stage at one time. And it remains illegal to sell marijuana you grow.
Q: Then what?
Holmes: That’d be for a 4-by-4-foot area, so you’ll need only one grow light, plus one grow light with a white-blue vegging light bulb and an orange-red flowering light bulb.
