Location, Location
Although cannabis will grow in many hostile places the more favourable a location is the better the results will be. Wherever your plants are they will need to receive the right amount of warmth, light, fresh air, water and nutrients. You will have to provide these things if nature is not.

Indoors or Out
Both indoor and outdoor growing have their advantages and disadvantage depending on your situation and location. If you grow indoors you have more ability to control your plants environment and are not restricted so much by the seasons. If you grow outdoors you can grow larger plants and there's no electricity bill.

Indoor Growing
Choose a space with a stable environment that can be controlled as much as possible. As temperatures in loft spaces can become extreme in both summer and winter they are not ideal unless well insulated or used only in milder months. Cellars, spare rooms or cupboards are better for more successful year round growing. Wherever your space is it will need good ventilation, a power supply and a reflective wall covering like matt white paint to increase light intensities around the plants. If flowering you will also need to make sure your plants are in a space able to get 12 hours undisturbed total darkness each day.

Be a Good Neighbour
A working grow space has the potential to be a huge annoyance to neighbours. Fans, pumps and ballast's can make a right racket when working, think about whether your noise might disturb a neighbour and use sound insulation if necessary. Check at night when things are quiet and background sound is at a minimum. Smells or powerful light beams escaping at night are other areas that you should also check and control.

Living with Plants
Plants in living rooms will not flower properly unless they receive the correct amount of darkness to trigger flowering. If you don`t want to sit in darkness for 12 hours a day cover plants daily with a box or black plastic bin.

Outdoor Growing
For outdoor plants choose a south facing location (northern hemisphere) that receives at least 4 hours of direct midday sun each day. Like a solar panel cannabis will work better, and produce more output the more direct sun it receives. Planting straight in unimproved soil will almost always bring disappointment so use compost, sand and other improvers to break up the ground and make life easier for the roots.

Move-ability
Although growing in pre-prepared holes in the ground is fine for some situations using pots outdoors has many advantages. Plants become easily movable so if bad whether is forecast or pests start attacking they can be taken off and treated or protected. Burying the pots in the earth is another option, it will help keep water and nutrients directed around the roots during dry spells and if they need to be moved they can be dug up pot and all without over stressing the plant.

Greenhouses
Greenhouses or polytunnels are great places to grow but need their environments controlling and managing in much the same way as indoor spaces. Ventilation is vital to combat too much heat and humidity as well as helping to deter mould and fungus. Insect problems also occur more easily in greenhouses than anywhere due to their protective environment being so easily accessible from outside.

The Right Plants
While some plants bred for outdoor growing might do well in an indoor environment it`s a good idea to get the right plants for the right place. If you want to grow outdoors and get good results choose a variety that's bred to grow outside. Plants bred for indoor growing won`t have been designed for the rigours of outdoor life. Likewise if you want to grow indoors choose an indoor variety as they will be bred to be more compact, shorter and tolerant of low light levels. As a general guide mainly Indica varieties are small, compact and bush like while mainly Sativas varieties tend to be taller, leggy and often more fussy about their conditions.

Micro Climate
Micro climates are pockets of differing conditions within a specific area either inside or out. If you live in an area where conditions are poor you can seek out or create a micro climate more favourable to growing cannabis. Fences, plants, buildings and your geographical location all play a part in effecting and creating local micro climates. Even the colour of a plants surroundings effect the light and heat intensity around it. Matt white is great at reflecting light and keeping things cooler while matt black is good for absorbing light and keeping things warmer.
