Hey, Cannabist!
Can cannabis be grown to flowering outdoors in Colorado, or do September temperatures cause the plants to freeze first? Or, are there mechanisms, besides daylight hours, that govern the flowering process? –Greenhorn Green Thumb
Hey, Greenhorn!
Yes, cannabis can be grown outside in Colorado in the summer. (Here’s a refresher on the .) I asked Justin Griswell, the blue-ribbon winner for best household marijuana plant at this year’s , for his thoughts on the topic. Griswell, also known as , teaches home cultivation classes and has written several grow books.
The growing season in Denver is . Griswell says indica strains have a growing season of 115 to 130 days and sativa strains mature in 145 to 165 days, depending on the specific genetics. will happen in late September or early October. The first frost is not too concerning, Griswell says, because the frost is usually light. Gardeners need to be concerned about hard frosts (a.k.a. killing frosts), which damage plants. With the turn of the seasons, watch the weather forecasts closely and if a frost is predicted, put a sheet or blanket over the plants overnight, like you would with tomatoes, so the plants retain ground heat. Plants should be harvested by the second or third frost.
Besides daylight hours, Griswell points out the flowering process can be governed by auto-flowering genetics. Ruderalis strains grow for 30 days and then flower for 30 days. Ruderalis strains have been genetically developed in Europe over the past ten years from European, Russian and Chinese strains, according to Griswell. These new strains were higher in than and had limited appeal to recreational consumers. Strains are now being developed with higher THC content. Ruderalis genetics are not commonly found in Colorado.

Hey, Cannabist!
You are doing a great service to Coloradans and everyone who reads The Cannabist. My wife and I are considering retiring to Colorado. How long does one have to be a resident before obtaining a medical marijuana card? I see that you can become a new resident of Colorado after living there for 90 days, but I haven’t found if there is any rule about the medical cards. Thanks, and keep up the good work! –Texas Twistem
Hey, Tex!
Flattery will get your question answered, pronto! There is no waiting period. I double-checked with marijuana attorney and Mark Salley, public information officer for the Colorado Department of Public Health and Environment. Both confirm there is no waiting period. A patient applying for a medical marijuana card in Colorado has to show , for example, a utility bill or government-issued benefit letters or retirement statements, among other documents. Once residency is established, you can .

Hey, Cannabist!
Hi, I am relatively new to marijuana and am looking for a strain that gives the effect of being very horny. Can you recommend the variety I should look for? –Randy Reefer
Hey, Randy!
Sex strains, what an arousing topic! Since you are looking for “very horny” strains, I sought out the recommendations of the Calgary, Alberta-based author of “,” which got a .
Kirkman suggests to look for varieties with a maximum hybrid ratio of 70/30 percent. Hybrids are better than 100 percent pure strains for beginners and occasional users to help avoid extreme effects of indicas (sleepiness) and sativas (paranoia). With a hybrid, according to Kirkman, the indica relaxes and the sativa gives an energy boost.
The Sex Pot author’s favorite sexy strains include , as well as Flo, Skunk #1 and Blueberry. I hope this info points you in the right direction! XO
