Items Required To Grow Hydroponic Marijuana
growing hydroponic marijuana
index Floor Covering: The area where the hydroponic system is placed might need some kind of floor covering that will protect it from water and nutrient spills. A thick drop cloth (the thick plastic sheets painters use to protect items from paint damage) will do a good job. Look for one that is the right dimensions, they come in many different sizes.
Fluorescent Lighting: Begin with a standard 48 inch fluorescent lighting fixture that holds 2 bulbs when starting clones or seeds. Fluorescent lighting should be used for the first two weeks (or longer). For flowering you will need mh or hps light. Use cool white fluorescent bulbs rated at 30-60 watts.
Grow Books And Movies: If you haven't purchased any of the materials needed to setup your hydroponic operation, watch a movie or read a book to get a good understanding of everything involved before spending a lot of money. They will show you how to plan your grow room and the steps involved in growing marijuana. This is a very cheap way to decide if growing marijuana is something you wish to try. If after reading or viewing them you are you sure you want grow, you can invest in the items you will need.
Hydroponic System: The hydroponic system you choose is a matter of personal preference. At the present time I use an NFT type of system. It covers a 4' x 4' area and works well with a single 400 watt light. Harvest size with a mainly indica strain is a minimum of 8-12 ounces every 12-16 weeks.
Lighting System : When growing a mainly indica strain, a single 400 watt hps or 400 watt mh grow light will allow you to consume a bit over 2 ounces of marijuana per month. A single 250 watt hps or 250 watt mh grow light will allow you to consume a bit over 1 ounce of marijuana per month.
Light Hanger: As the plants grow the height of the hps/mh light must be increased so as not to burn the tops of the plants. You can buy a pre-made light hanger or make one yourself with stuff you find at a hardware store. Pre-made light hangers may also be sold as 'vertical light movers'.
Marijuana Seeds: Novice indoor growers (either with hydroponics or soil) should choose a mainly indica seed strain that is easy to grow indoors. As you gain experience, you could move up to an indica/sativa mix and advanced growers might want to experiment with a mainly sativa strain.
Media: Some types of hydroponic systems require media for the plants roots. As far as is known, rockwool can be used in all hydroponic systems that utilize media. However, it is best to follow what the manufacturer of your hydroponic system recommends.
Nutrients: Depending on the stage of growth, plants have different nutrient requirements. You have to use nutrients designed for hydroponics, do not use nutrients for plants grown in soil.
Oscillating Fan(s): A good way to circulate air in the grow room is an oscillating fan. Depending on the size of your grow room, one or more 12" to 18" units may be used. For the first time grower, a cheap model ($20-$40) designed for home use is preferred over an expensive heavy duty industrial unit.
pH Related: You will need something to measure and change the pH of the nutrient solution. The most commonly used tools to accomplish measurements are pH test kits or pH meters for measuring liquids. For adjusting the pH of a nutrient solution, pH-up and pH-down are used.
Scissors: A small pair of sharp scissors for cutting off dying leaves and other small jobs will be needed. Also a pruner or some other cutting tool will be needed to cut down plants. In most cases the stems will be 3/4 of an inch or thicker at harvest time. Only use these cutting tools for working on your marijuana garden and keep them clean.
Thermometer: A thermometer will be necessary to monitor temperature. A normal household thermometer that can measure between 50-90 degrees F will work.
Timers: You will need a timer to turn your light on and off and some systems require a pump and another timer to circulate the nutrient solution. Lighting systems need a heavy-duty grounded timer, but pumps and fans that don't consume much power can run on light duty timers. A heavy-duty timer can be used to run a small load, but a timer designed for small loads might be cheaper.
Water Containers: Tap water has to be aged for at least 3 days before being used with plants. 3-5 gallon containers do a good job of storing water and aging it. Do not use containers that might have been used to store anything other than water. If the tap water is really bad in your area, you may have to use distilled water or water that has been treated with reverse osmosis.
