Outdoor grow shows are dominated by climate, soil, and water supply whether you are planting in a remote mountain patch, a cozy garden in your backyard, or on your balcony.

Microclimates are mini climates that exist within larger climates. Maps are available of these areas. Many maps such as the United States Department of Agriculture (USDA) Hardiness Zone map,

The map divides North America into ten zones plus zone 11 to represent areas that have average annual minimum temperatures above 40°F (4.4°C) and are frost free. Look into detailed microclimate maps for your grow zone. One of the most detailed climate maps can be found in Sunset's Western Garden Book, Sunset Publishing. The map details 26 distinct climate zones in 13 Western States and British Colombia and Alberta, Canada, This is the best climatic map available for the area.

Europe and other countries have much climatic information available via the Internet. Check out rainfall, temperature, and humidity charts for virtually all large cities in the world and most geographic regions. Visit for specific information on your local weather.

Temperature, rainfall, and sunlight vary widely across the globe, providing unique growing environments and countless microclimates. Look for specific information for your climate at local nurseries and in regional gardening books and magazines or through the department of agriculture (County Extension Agents) in your area. Here is a brief rundown on the qualities of different climates.

Coastal climates like those found in the Northwestern United States, British Columbia, Canada, Northern Coastal Europe, and the United Kingdom, etc., are cool and rainy. Annual rainfall most often exceeds 40 inches (103 liters per m3) and can be as high as too inches (253 per m5)! Winter blows in early in these areas bringing a chilling rain and low light levels. The more northern zones experience shorter days and wet cold weather earlier than the southern zones. Crowing outdoors here is challenging because the temperature seldom drops below freezing, which contributes to larger insect populations. Some of these cold coastal rainforests are packed with lush but invasive foliage and fungal growth brought on by the cold and damp.

Clay soil witli a low pH is common in moist coastal zones. See "Clay Soil" below for more information.

Start Clones or Seedlings Indoors

Get a jump on the season by starting clones and seedlings under lights indoors. Move small containerized plants into heated greenhouses to start hardening-off. Transplant to a backyard or secure guerilla patch once they have become hardened-off and are more resistant to environmental stress.

Beat the cold; start seedlings and cuttings indoors and move them into a heated greenhouse in March or April. A 400-watt HP sodium lamp on a timer can augment the less-intense natural light of early spring. Seedlings and clones will need at least 14 hours of artificial and natural light per day until plants are transplanted outdoors.

Alpine mountain climates are cold much of the year. Freezing temperatures, mineral-heavy acidic soil, and wind top the list of grower concerns.

Summer temperatures in the mountains can dip to 30°F (-TC) or lower in the summer, at as low as 2000 feet (610 m) elevation. Temperatures below 50°F (I0°C) virtually stop growth, and temperatures below 40°F (5°C) can cause foliage tissue damage in many strains. Low temperatures cause stress in plants and a reduction in harvest weight. On the other hand, plants in high alpine climates tend to produce more resin and 10-20 percent more THC than those in lower gardens.

Most alpine soils lack humus, and strong winds will dry out the plants. For best results, look for patches where pasture grass grows.

You can help your plants deal with mountain stress by backfilling planting holes with a mix of peat moss, soil, polymer crystals, and slow-acting layers of organic fertilizer.

Cold wind causes moisture loss, and plants dry out quickly. This causes stress which can weaken plants and leave them open to attack by disease and insects.

Guerilla-grown buds suffer many days of wind, rain, hot sun, and cooi nights. Such stressful conditions often impair resin production.
Polymer crystals mixed in the soil absorb water and release it over time.

Cool mountain environments, like those in Switzerland or the Rocky Mountains of North America, usually experience first frost in September and last frost during May.

Spring and fall months are rainy with a dry period in July and August. Cold rains in the fall can cause mold. Planting early-maturing strains helps avoid weather problems.

Rain and wind coupled with heavy buds broke this plant. Tied together with nylon rope, buds were supplied with enough fluids to produce a healthy harvest.

Tropical climates are generally warm to hot and humid. Rainy and dry seasons vary by location. Most jungle and tropical climates have daily rains. Protecting flowering females from rain with a greenhouse will help avoid hud mold and other problems, The closer to the equator, the less deviation there is between the length of days and nights. Extra hours of artificial light are necessary to keep plants in the vegetative growth stage. Tropical sativci strains are often favored in these regions because they are acclimated and require little special care.

Nighttime temperatures and humidity are often high. In fact, extended nighttime temperatures above 85°? (2S°C) will cause plants to stop growing. Nighttime cooling could be necessary to keep plants growing well.
