What Things Do I Need to Grow My Own?

BC Northern Lights has been around for over a decade, and throughout those years, we've done extensive research and testing to make sure that everything that we put into our grow boxes is not only efficient, but also effective.

Each item that we include with our grow boxes has a function, and chances are that without it, your grow box wouldn't be the same.

To give you a better idea of what each part does, we decided to break it all down for you. And yes, if you're looking to build your own, these are the parts that you need.

Note: these items are for if you were growing from clone as opposed to seed.

Hydroponic tub

This is what will hold all your water and nutrients, as well as your plants' roots, so make sure this is clean, big, and, well, can hold water. 

Lid for hydroponic tub, with holes (for mesh pots)

The lid should fit snug over the tub, but not too snug, as you'll need to water and add nutrients to your plants weekly. The holes should fit the mesh pots that hold your lovely little plants. 

Mesh pots

These are what house your clones. Your clones should be transplanted into rockwool and placed into these bad boys. The pots will then sit in your tub lid, and the roots will dangle into the tub full of water and nutrients.

400W HPS bulbs

We've found the most success with HPS bulbs for flowering; they seem to work really well with BCNL grow boxes. Would a higher wattage mean quicker flowering? No, young padawan, it doesn't mean that. In fact, a bulb with too high of a wattage might burn your plants and unnecessarily use extra electricity.

H2O pumps and adapters

The water pumps and adapters help pump water from the hydroponic tub into your irrigation whips, which feed into your rockwool where your plants sit. Very, very important.

Vent covers

Vent covers should be curved convexly so that they can deflect light from the back of the unit. They should attach to the back of your grow box, near where the fan should be.

3" rockwool 

This is your ultimate growing medium. They retain water beautifully, which is crucial in the event that your growing appliance's timer or pump goes out, or worse, if there's a power outage. 

Rockwool also holds around 18% air minimum at any given time, giving your roots lots of oxygen. Yes, your plants like oxygen.

Lastly, it's a lot less messy than soil. One tip, though, is to always handle with gloves, as the fibres and dust from the rockwool could irritate your skin. Also make sure to not aggressively inhale that stuff.


COis important for your grows as it'll help increase yields. The COregulator will do exactly what it implies: help regulate the amount of COthat goes into your plants.

Irrigation whips

These guys are what will take and carry your nutrients and water into your rockwool, and actively feed your plants.  

12" air stones and airline whips

Air stones are one of the most important items on this list as they're what aerates your water. Without aeration in the water, your roots, which are sitting in water, will rot due to the lack of oxygen. Keeping the water moving will prevent this.

Airline whips attach the air stones to the water.

Block covers

Block covers will prevent your rockwool from drying out too quickly, covering the rockwool and protecting them from the lights above. These can be as simple as pieces of cardboard that doesn't mind a little bit of water getting splashed on it every now and then.

Can filter and filter mount

If you're worried about odors, then this is important. The filter is what'll help your grows stay discreet by minimizing your "tomato" plant smells. Brands are ONA Block are great for this purpose.

Internal fan(s)

Because of all the heat that your lights will create, you're going to need something to cool your plants off, and a fan that you can attach to the inside of your box can alleviate your plants from overheating (or worse—dying!).

Fans also encourage better air circulation, and actually can help strengthen your plants because it will be trained to withstand the breeze, forcing them to stiffen up those stalks.

Surge protector

This one is a pretty self explanatory one. A surge protector will protect your growing appliance from any power spikes due to storms, power outages, and anything electrical that's out of your control. 

pH up and pH down

Sometimes your pH may be a bit out of whack. It's nothing to stress out about, but keep some pH up and pH down handy so that you can balance that shit out.

Mixing tub

Every week or so, you'll need to add water to your hydroponic tub with nutrients added to the water. A giant tub (for example, a Rubbermaid bin) will be able to hold the amount of water you need to fill your hydroponic tub. Ideally, your mixing tub would have some sort of drain hose so that you can fill your hydroponic tub with control. 

Also, when you do change up the nutrients, you'll need a chair so that gravity can help the nutrient water go down that drain hose.

Measuring syringe

This is for when you need to measure out exactly how much nutrients you need to mix into your water. A syringe is good because you can be really precise, and not have to touch any of the nutrients by hand, some of which may be bad for your skin.

Nutrients (duh)


Evidently, if you were to build your own grow boxes, there are a lot of items to acquire and collect. And, as we say in the biz:
