What are the equipment for small marijuana grow room? -For beginners

Tent or Liner
You'll need to make sure that the inside of the room or tent is as reflective as possible (to maximize your grow light's output). You'll also need to ensure that no outside light can penetrate into the room or tent (mandatory for seedless flowers). The easiest way to satisfy both of these requirements is with the use of a grow tent or a room liner.Grow tents and liners are typically made of canvas, Mylar and/or black & white poly film. In addition, these films provide a truly separate environment that will help keep bugs and mold out of your grow area.

Grow Light
Since you are growing indoors, you'll have to select a grow light to replace the sun. There are several different types of grow lights and unfortunately, there is no 'best'. Choosing a grow light comes down to the dimensions of your space, your budget, your growing goals, and your power limitations. The good news is, lighting technology has improved over recent years and nearly all lights - HPS, CMH, LED, and DE will work.

T5 Fluorescent Tube Lights- These will aid in the vegetative stage of your plant and some even have IR and UV spectrums to help with resin production during the flowering stage of growth.

For beginners, I would recommend either compact florescent light ("CFL") or LED lights. LED grow lights cost more. But with LED lights you'll save on your power bills, and your yield will be better.

Extraction Fan
An extraction fan is essential for keeping temps down and supplying the plants with the fresh air (C02) they need to thrive. Note that you do not necessarily need an extraction fan if you are running a sealed room - but you will need an A/C and CO2 generator, which is a significantly more expensive alternative. I've written a more in-depth article that explains why you might choose a sealed room over a vented room.

Carbon Filter
As the plants enter the flowering phase, they start to give off that pungent odor we all know and love - unless you're the neighbors. Carbon filters are the answer to that terpene-rich, skunky weed smell. You definitely don't want to get a cheap carbon filter - make sure you stick to reputable brands when it comes to this essential piece of equipment!

Ducting
Although not glamorous, ducting is a crucial item in your garden's ventilation system. For smaller grows, I recommend flexible, insulated ducting - the insulation helps keep the heat (caused by the hot air) from radiating into your growing area. I recommend using 6 inch ducting at a minimum; larger grows will benefit from larger diameter ducting.

Circulating Fan
Circulating fans simulate nature's gentle summer breeze. The more the merrier here, just make sure they have adjustable speed settings - you'll notice I said gentle breeze, not gusting tornado.

grow Medium:

I don't know if technically medium can be classified as equipment. However, medium (what you are using to grow your plants) is very important. Regular potting soil is perfectly fine for beginners as it tends to be more forgiving of mistakes than hydroponic mediums like coco coir.

Small Pots (One to Two Gallons):

To prevent over watering, you'll use small pots for weed clones and also marijuana seedlings. Every plant should have its own pot.

Large Pots (Five To Seven Liters) :

Large pots are where you want to transfer your plants when they get bigger and begin flowering.

Thermometer/Hygrometer:

To ensure an optimum yield, you will need to make sure your room or tents are at the correct temperature and at the optimum humidity. A combination of thermometer and hygrometer will allow you to do just that, and they are cheap at less than $20. So, buy one!

Cannabis seeds or seedlings:

Last but certainly not least, you need something to grow! You can either choose to pop seeds and grow the old fashion way, or you can get some clones and quickly and easily start growing pants. You'll want to love them, pamper them, and most of all feed them properly.

Filtered Water
The final piece to the puzzle is ensuring you have access to clean, filtered water. The sad fact is that most city water is less than ideal for growing cannabis - its full of contaminants, chlorine, chloramine, fluoride - the list goes on. You don't need an expensive filter, and if you can't afford one, you still have two other options - go to the grocery store and fill a 5-gallon jug with RO water for 25 cents per gallon, or get some air stones and bubble the water for a minimum of 24 hours.

Finally

And there you have it! A lot of these things you can find at a local hardware or gardening shop, but the first few though (lights, fans/filters, nutrients, and soil) may be available only at specialized hydroponic stores. With that said, we want to leave you with a couple of thoughts:

The lights and ventilation system the most important growing essentials of your biosphere experiment. Think of it as the Heart and lungs of the tiny ecosystem you are creating in your home.

Your nutrients and medium are like the food and stomach of your garden, and without food for your plants to eat they will not grow- even under the best light

Keep in mind that grow equipment weighs quite a bit and you need to suspend or place it all in optimal positions throughout your grow

Take it easy, take your time, and make a good plan
