When it comes to growing your own cannabis there are many different growing techniques and methods for growing marijuana in your home. While many growers choose to grow their plants from marijuana seeds which means you have to buy cannabis seeds, and germinate them.

Remember, only female cannabis seeds flower and grow buds so while regular seeds from reputable seed banks have a good chance of reaching the flowering stage, only feminized seeds guarantee this. As some of you probably know, you can also clone marijuana plants. Cloning requires taking a cutting from another cannabis plant (often referred to as the ‘mother’) before it reaches the flowering stage and replanting it. A quick search of how to clone marijuana plants will bring up a list of all the equipment required, so hopefully this guide will help you figure out how to clone weed plants cheaper and easier.

Now, you may be a little confused about where to buy a marijuana clone box and also how much it will cost. But, as long as you have a spare cabinet or closet, you can customize it to have three chambers. One would, of course, be for clones and another for seedlings. For flexibility, you would also have another space for germinating seeds, and another for vegetating or keeping mother plants. Therefore it is possible to make your own cannabis clone box, thus saving you time and money.

How do you Turn a Cabinet or Closet Into a Marijuana Clone Box?

Simply put, you can put a couple of shelves in a cabinet and install CFL grow lights, fans, and carbon filters to build a three-chamber grow room. Not only can you raise cuts and seedlings, but this DIY clone box also lets you germinate marijuana seeds and keep vegging plants. This will allow you to grow marijuana seeds like Afghan Kush and Alien Gorilla Glue while also having a clone of another cannabis plant such as God Bud growing in the same space.

Materials Needed

The materials detailed in this article are well suited for a cabinet space measuring 120cm (L) x 45cm (W) x 150cm (H). What you have in the house may not have the same dimensions but it’s tweak the materials you need, such as using more powerful lamp wattage if you have a bigger space, to make your DIY cannabis clone box work.

The items you need to prepare are widely-available and also reasonably priced. Incredibly, even with this cheap makeshift grow room, you are not compromising too much with regards to potency and yields.

Essentially, you will need these materials:

  • 6 x 60w CFL
  • 2 x 200w CFL with reflector
  • 1 x flange
  • 1 x 2m ventilation hose
  • 1 x Exhaust fan
  • 1 x Carbon filter
  • 1 x Mylar foil
  • 14 x bolts and nuts

Keep in mind that you will also need other tools to help with set up and maintenance of your cloned cannabis plants. One important extra is a digital thermometer/hygrometer combo meter. Other materials that you need include screws, electrical wires, and shelves.

Setting Up the Cloning Grow Box

Setting up a cabinet to be your ultimate weed grow room for clones, seedlings, and vegetating marijuana plants takes only a bit of work. Here’s a little guide to give an outline of how you can achieve the best results.

Divide Into 3 Chambers and Install the CFL Lamps

A typical cabinet or closet would be too large for it to be used only for cloned cannabis plants or seedlings. Hence, it is better to divide the space so that you would have a dedicated area for germinating marijuana seeds and another one for plants in the vegetative stage.

You could create a chamber for cannabis seed germination by fixing a shelf with a 10 inch gap from the ceiling. Although light is not necessary, a couple of CFL lamps in this section will warm up the space.

Add another shelf to create two more chambers. The middle section should have a vertical clearance of around 15 inches, giving it enough space to house up to 200 clones or seedlings.

You can compute how many 60w CFL lamps to install. Generally, each clone or seedling would need 1 to 3 watts. If you were to choose four bulbs, then you could house 80 to 200 young plants.

The bottom chamber would have a far more space to house growing marijuana plants in the vegetative stage. At the very least, it should have a clearance of 25 inches or more. Install the two 100w CFL lamps with reflectors here.

In regards to electrical wires, you can route them out of the growing space through an air hole. As for the lamps, you can spread them apart so that they provide an equal distribution of light for your cannabis plants.

Provide Adequate Ventilation

CFLs do not produce much heat. Even so, you will have multiple bulbs operating at the same time – depending on how many plants you are growing. Based on the number of lamps described in the above section – that is a total of 760w if you have all of them turned on. In a closed environment, the heat will accumulate over a period.

Two things to consider are air circulation and ventilation – both of which are integral to healthy growth. A couple of things are needed to provide optimal atmospheric conditions inside the growing space:

  • A means to move air
  • A way to bring in fresh air while expelling hot and stale air

Because warm air rises, you could cut a hole in the top of the closet, above the germination chamber. That will be where you install a carbon filter and an exhaust fan. Once turned on, it will create a vacuum effect inside the grow room, which will then pull in fresh, cooler air from outside.

Even if they are not in the flowering stage, your cannabis plants will still produce the unmistakable odor of marijuana. Allowing it to escape into the rest of the house can become overwhelming. Letting the smell of cannabis drift into the neighborhood could annoy some people. So be aware of the environment which you are growing and take precautions not to disturb others in your house and neighborhood.

Hence, as the fan draws warm air that naturally rises, the carbon filter will first remove odor particulates. Once expelled, there should be no trace of the smell of your marijuana plants.

Your cannabis plants also need fresh air to replace stale air. One of the reasons for that is to augment oxygen. Although they absorb oxygen molecules from water moisture in the medium, the leaves could also take oxygen directly from the air. For the weed plants to thrive better, they will also need carbon dioxide during the daytime cycle to manufacture sugars. Drawing in fresh air replenishes the available CO2 for the plants to absorb and utilize.

An exhaust fan is not only a means to expel warm air to keep the temperature range in check but it also lets you circulate and keep the air fresh.

Maximize Lighting

One of the last things you should do after setting up the CFL bulbs, exhaust fan, and carbon filter, is to cover the entire interior wall with mylar foil.

Not all of the light produced by each CFL lamp goes to the cannabis plants. Instead of wasting them, the reflective surface on the walls would reflect them and direct them where they are needed – the marijuana plants. During daytime cycles, the idea is to provide as much light possible without raising the interior temperature excessively or causing light burn to your growing cannabis plants. Think of it as maximizing the energy manufacturing capacity of the marijuana plants to boost growth.

A Stealthy and Secure Clone Box

Using a cabinet (or closet space) takes away the cost of buying a grow box or tent. At the same time, visitors coming into your house will not even know that you are growing marijuana. Lastly, it is easy to secure and lock up, as is required by state laws.

The setup described in this article lets you keep marijuana plants in a perpetual vegetative stage, from which you could obtain cuts. It has a chamber where you could grow the clones before transferring them to another grow room explicitly for harvesting buds eventually. It is also a versatile clone grow box in that you could start from seeds and nurture young seedlings.

As you can see, turning a cabinet or closet space into a highly functional area to grow marijuana is quite easy to do. The most difficult part will be choosing your marijuana seeds, regular marijuana seeds, autoflowering seeds and feminized seeds can all grow plants which you can cut from to clone.

After you have chosen which cannabis strains you would like to grow, all you have to do now is to draw up your plans, get the necessary materials, and start building it.
