Get expert tips on growing premium indoor medical marijuana

Growing weed indoors has many advantages, it is a fact that growing medical 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 medical marijuana indoors you can control the ambient conditions just exactly as you want them and grow a nice healthy cannabis plant.

Feminized medical 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.

Plant growers are interested in LEDs because they are more energy efficient, emit less heat (can damage plants close to hot lamps), and can provide the optimum light frequency for plant growth and bloom periods compared to currently used grow lights: HPS (high pressure sodium), MH (metal halide) or CFL/low-energy. However, LEDs have not replaced these grow lights due to higher price. As mass production and LED kits develop, the LED products will become cheaper.

As we know, the HPS, Incandescent Lamp and Fluorescent Lamp emit all the spectrum of visible light & some sightless light, but LED Grow Lights only deliver the colours of light used by plants for efficient and healthy growth!

LED Grow Lights are the newest and most efficient way to grow plants indoors! This revolutionary form of light is different from other traditional lights, such as High Pressure Sodium (HPS) or Metal Halide (MH). LED Grow Lights bulbs are comprised of multiple low-watt light sources, working together on a single board. HID lighting is extremely inefficient; it generates a lot of heat while only producing 30% photosynthetic light. Unlike HIDs, 1W LED emit very little heat because all the power is efficiently converted into targeted light wavelengths for plants. For this reason, additional fans, ducting and AC are rarely if ever necessary. Additionally, LEDs will last 50,000 before they’ve lost even 30% of their initial output, not to mention they’re still 100% functional! So there is no need for yearly or bi-yearly bulb changes, as 50,000 hours is 6 solid years, and after that you can still continue using the light! Lastly, LED grow lighting use 65-70% less energy than traditional HID lighting, while producing the same or better results. With no additional cooling costs, bulb costs, and decreased electrical costs every month, imagine what you can do with the extra money!

 

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.

  1. Think of LED light on plant growth have such a role, I believe your methods and theories, which are LED lights to create a miracle!
