How to grow Medical Marijuana

Growing weed indoors has many advantages, it is a fact that growing marijuana outdoors makes it very easy to lose your crop from theft or possibly the law if it is illegal to grow where you live. By growing marijuana indoors you can control the ambient conditions just exactly as you want them and grow a nice healthy cannabis plant.
Feminized marijuana seeds are an excellent choice when considering growing pot indoors.
Plants grown indoors will not appear the same as their outdoor cousins. They will be scrawnier, appearing with weak stems and may even require you to tie them to a growing post to remain upright, but they will supply more resin if looked after correctly.

About Hydroponics
Hydroponics is the name given for a variety of techniques for growing weed without soil. It was realised by researchers studying plant metabolism that plants took in their nutrients as simple inorganic ions, and that soil, while a source for such nutrients, was not essential. While a plant’s nutrients come from the soil, the only nutrients a plant can successfully absorb are those that dissolve into the plant’s water supply. When the required nutrients are introduced into a plant’s water supply artificially, soil is no longer required for the plant to thrive.
Nutrient Film Technique (NFT)
In this method, the plants grow through light-proof plastic films placed over shallow, gently sloping channels. A steady flow of nutrients is maintained along the channel, and the roots grow into dense mats, with a thin film of nutrient passing over them (hence the name of the technique). A downside of the technique is that it has very little buffering against interruptions in the flow eg power outages, but overall, it is probably one of the more productive techniques.
Basic Kit to Grow Indoors Simple Pot and NFT Set Ups
You don`t need a lot of kit to start growing great flowering plants in a cupboard, wardrobe, attic or grow space. Apart from the plants the lamp is the most important thing. There are two types used for growing light hungry plants. Metal Halide (MH) or High Pressure Sodium (HPS). HPS lamps used with horizontal reflectors (shades) produce the most usable light per watt of electricity and flowering plants love the light they produce. A 600 watt HPS lamp will light about 1 square meter of growing space. All the kit listed below can be found at a grow shop near you.
Basic Kit to Grow in Pots
1. High Pressure Sodium Lamp (600 watt is the most efficient but a 400 watt may suit a smaller space).
2. Fan running 24 hours a day if possible and oscillating.
3. Pots, trays and chosen growing medium. 50% potting compost 50% Perlite is a basic mix. Raise the pots in the trays with bricks or bits of wood so they don`t sit in a puddle when watered.
4. 24 hour timer to control light periods. This should be used with a high power switch known as a contactor or relay switch as grow lamps can easily burn out regular timers used on their own.
5. A pH tester to test water and nutrient feed solutions.
6. pH adjuster such as phosphoric acid to adjust water and feed solution to around pH 6.0 – 7.0.
7. Nutrients, ones aimed at growing the plant you want to cultivate are best.
8. Matt white paint or white plastic to cover the walls of the grow space.

Also useful are a measuring bucket, measuring jug, large syringe and pea netting or string to support top heavy plants. If you can afford it a great help is a Total Dissolved Solids (TDS) meter. These allow you to check the nutrient levels of feeding solutions to make sure they are optimised for your plants.
Growing hydroponically in a Nutrient Film Technique (NFT) Tank is really simple and not something to be afraid of. In fact some beginners to growing may find it easier than using soil mixtures in pots. You do not have to judge if the plants need watering or feeding so much using NFT, as long as you follow the simple instructions supplied with the tanks the plants should look after themselves.
Basic Kit to Grow in NFT Tanks

1. High Pressure Sodium Lamp (600 watt is the most efficient but a 400 watt may suit a smaller space).
2. Fan running 24 hours a day if possible and oscillating.
3. NFT tank with pump and spreader mat (these come with the tank), Rockwool cubes.
4. 24 hour timer to control light periods. This should be used with a high power switch known as a contactor or relay switch as grow lamps can easily burn out regular timers used on their own.
5. A pH tester to test water and nutrient feed solutions.
6. pH adjuster such as phosphoric acid to adjust water and feed solution to around pH 5.2 – 6.0.
7. Nutrients, ones aimed at growing the plant you want to cultivate are best.
8. Matt white paint or white plastic to cover the walls of the grow space.

Also useful is a measuring bucket, measuring jug, large syringe and pea netting or string to support top heavy plants. If you can afford it a great help is a Total Dissolved Solids (TDS) meter. These allow you to check the nutrient levels of feeding solutions to make sure they are optimised for your plants.
Also…
Wherever you decide to set up your grow space remember that the plants night time or dark period is very important. Check that when the light goes off the grow space is in total darkness. Proper ventilation for the grow space should also be considered as the area can become very humid. Opening up the space daily may be enough but larger areas may need extactor fans to avoid problems.
