Growing in the Arizona desert at 115-120 degrees

Now that it's legal, I see a lot of people ask if they can grow medical marijuana here in the Arizona desert, the simple answer is yes.

The reason people don't grow huge crops in the desert like in Northern Arizona or California, is that it's desert. It's a little hard to hide a bright green 5-10 foot plant in the middle of miles of sand.

Marijuana grows great in the desert, marijuana loves the sun. In fact a plant that was shaded from afternoon sun only grew half as big as plants in direct sun.

Studies show marijuana produces about one ounce per sf of canopy. This seems to be correct information. A friend with a 6X8' grow area (48 sf) with about 30 plants, 3' tall, it produced 3 pounds, or 48 ounces.

the Arizona Medical Marijuana Act allows patients to cultivate 12 plants that must be grown in an “enclosed, locked facility”, defined as “closet, room, greenhouse, or other enclosed area”.

Other enclosed area can be a fence as long as it only permits entry by the patient or caregiver. So build a fenced area or greenhouse rather than an expensive to operate grow room.

If patients are allowed 2.5 ounces every 14 days, that works out to 4 pounds a year. So a patient should be able to grow one crop a year and have their 4 pounds of medicine.

you cant there is no way it is to hot you would want to make a green house to keep the temps down i would love the sun but the desert has realy hot temps during day and drops low during night it is not the pefect growing conditions. If you build a green house you could keep the temps were you want them why still geting the sun of the desert.

You obviously don't live in the desert. It would be 190 degrees in a green house, just like in a car. Please don't post what you've read on a web page about temperatures. I've grown here, it works great. Many grow rooms get over 100 degrees in summer, especially here in Arizona.

i would put ac in the green house just like i got in my house why not he said it gets 115-120 you better water alot that heat is killer. gl veging in that rofl!! if you dont want to in est in green house go with some mess cloth to shade your plants and give light you can get at homedepot atleast your plants will be in shade!! that is all you can do realy gl! 120 degrees is a auto killer of all your plants btw so hope it dont get hot. you have a better chance of growing inside were you can control your enviorment!! Also how mutch dose your temps change from day to night i now it is 120 during the day but what is it at night. when i think desert i think cold nights in the 40s. That is way to mutch of a change your plants will be small and will yeild nothing invest in some lights and grow in your house. you will yeild alot more and can grow bud all year round!!

they grow fine in the full sun just have to have ALOT OF WATER... and if you only want 4 pounds you should be able to get that from 4 to 6 plants

Also don't forget growing in AZ is only allowed if you live at least 25 miles from a dispensary. I live in Cali and AZ and I got to say when I grow I don't even bother trying in Arizona, not because of the weather (which sucks compared to the beach) its because of the laws. Watch out the Med law in AZ does NOT cover you like in Cali and other places plus the people here are not near as understanding or tolerant. Little food for thought

you can control temps in a green house... do you think they just don't have them in arizona? where are you getting your info from? lol

outdoor plants have different tolerances than indoor plants, so a hotter environment is more permissible. Of course, as mentioned, you might need to adjust your methods slightly (like more active watering). I was recently talking to someone with a vested interest in the arizona med issue, and he was saying that the legislature can overturn the vote, and that it looks like they will again, so you might want to double check that it'll last before you make any finite plans. PS, I live in the desert

ok i feel bad for you so here is some info i cant get threw to you so read up!

Marijuana plants are very hardy and survive over a wide range of temperatures. They can withstand extremely hot weather - up to 120 degrees - as long as they have adequate supplies of water. Cannabis seedlings regularly survive light frost at the beginning of the season. Both excessively high and low temperatures can slow marijuana's rate of metabolism and growth. The plants function best in moderate temperatures - between 60 and 85 degrees. As more light is made available, the ideal temperature for normal plant growth increases. In high temperature and moderate light conditions, the plant's stems elongate. Strong light and low temperature conditions will decrease stem elongation. During periods of low light, sem elongation can be decreased by lowering the temperature.
Temperatures below 50 degrees slow growth in most varieties of marijuana. When the temperature drops below 40 degrees, the plants may experience some damage and require about 24 hours to resume growth. Low nighttime temperatures may delay or prevent bud maturation. Some equatorial varieties stop growth after a few 40 degree nights.
A sunny room or one illuminated by high wattage lamps heats up rapidly. During the winter, the heat produced may keep the room comfortable. However, the room may get too warm during the summer. Heat rises, so that room temperature is best measured at the plants' height. A room with a 10 foot ceiling may feel uncomfortably warm at head level but be fine for plants 2 feet tall.
If the room has a vent or window, an exhaust fan can be used to cool it. Totally enclosed spaces can be cooled using a water conditioner which cools the air by evaporating water. If the room is lit entirely by lamps, the day/night cycle can be reversed so that heat is generated at night, when it is cooler out.
Marijuana is low-temperature tolerant. Outdoors, seedlings sometimes pierce snow cover, and older plants can withstand short, light frosts. Statistically, more males develop in cold temperatures. Low temperatures, however, slow down the rate of plant metabolism. Cold floors can lower the temperature in containers, thereby lowering root temperature and slowing germination and plant growth. Ideally, the medium temperature should be 70 degrees.
There are several ways to warm the medium. The floor can be insulated using a thin sheet of styrofoam, foam rubber, wood or newspaper. The best way to insulate a container from a cold floor is to raise the container so that there is an air space between it and the floor. Overhead fans, which circulate the warm air downward from the top of the room also warm the medium.
When the plants' roots are kept warm, the rest of the plant can be cooler without danger. Heat cables or heat mats, which use small amounts of electricity, can be used to heat the root area. These are available at nursery supply houses.
When watering, tepid water should be used. Cultivators using systems that recirculate water can heat the water with a fish tank heater and thermostat. If the air is cool, 45-60 degrees, the water can be heated to 90 degrees. If the air is warm, over 60 degrees, a 70 degree water temperature is sufficient.
Gardens using artificial lighting can generate high air temperatures. Each 1000 watt metal halide and ballast emits just a little less energy than a 10 amp heater. Several lights can raise the temperature to an intolerable level. In this case, a heat exchanger is required. A venting fan can be used to lower temperatures.
Greenhouses can also get very hot during the summer. If the sun is producing too much heat, opaquing paint may lower the amount of light and heat entering the greenhouse. Fans and cooling mats also help. Cooling mats are fibrous plastic mats which hold moisture and which can be purchased through nursery supply houses. Fans blow air through the mats, lowering the greenhouse temperature. They are most effective in hot, dry areas.

It was 113 degrees 15 days before this was taken....

In Az, you could grow outdoors all winter spring an fall, an summer would be the off season like winter is here?

Afganistan looks about like arizona lol.

This week it is 115 days never cools off more than 80 in the summer at night on a cooler day of 103. 40 degrees is winter temps at night in desert. Micro climates deep root watering and afternoon shade at
Least 30%.
