Well there is a bunch of things to know before you can really look at marijuana growing equipment and then again, looking at all the different equipment may give you some new idea’s! Equipment will vary depending on if you are growing marijuana inside or outside of course!
Growing inside requires a bit more in the form of equipment and planning! You will need containers, lighting, fertilizer, growing medium and gee a place to grow! As you get more into it you will need pumps, timers containers and plastic hose or pipe.
Normally plants grow on sunlight and water. The more sun a plant gets is good but the more water a plant gets isn’t good! If we can control the light and water a plant gets we are off to a great start. Marijuana is in it’s growing stage when light is above 12 hours and when that light is below that the plant will be in a flowering stage. We can easily force a plant to grow or flower by adjusting the amount o flight that plant gets related to hours. This is how someone can grow the same plants for a period of time, cut the light and make them flower, take whatever flowers you will and then turn the lights way back up to force the plant to start growing again! Cool too!
When we look at where we are going to grow plants in we can look at several factors, are we going to use hydroponics or are we going to water by hand at first? If going with hydroponics then we should be looking at a containers that we can easily cut and or seal and that will force the nutrients/water back to the bottom or a certain point that will run back to the pump by means gravity or a pump. There are many types of systems available in the market and looking at some of them you can easily design, purchase and install the stuff yourself! Here are a couple photos of hydroponic systems so you can see for yourself.
This is an Eb & Flow system, your water/nutrients are in the bottom container and when you lift the bottom tray the nutrients flow to the upper tray. When you set bottom tray back down the nutrients drain back to the bottom container. 
This system is a little more complex but still you can see the simple premise and could easily set one up with things you can find around the house! Everything is available at Loews or Home Depot or your corner hardware!
If you are going to grow in buckets and manually adjust things like light heights and watering times all you need is the lights , buckets, soil and fertilizer to feed your plants. Well of course water too! This takes a little more hands on but is very doable! Just make sure to make a schedule and try to stick by it for watering or turning on and off your light system.
Next we need to make sure we have the right soil in the buckets for the plants to grow well. If you are going with hydroponics, you may want to look into pea gravel or another substrate that will allow the roots to spread easily, give the plant support and also drain well so the roots dry. They do sell special substrate for this too! If your going to use all potting soil great but it can get expensive if you are going to use a lot. You can mix it with dirt from outside or you can use all dirt from outside if you have somewhere you can get enough. Potting soil is great because it already comes with everything in it you need to start your plants. The dirt from outside may need some things like lime to make the soil less acidic or fertilizers because lack of nutrients. Remember that this is weed, hence the phrase “grows like a weed”! It will grow anywhere almost! The more care the better the flowers!
