DIY: Cheap Indoor Grow Setup | Low Budget Grow Room

Last Updated: August 25, 2022By Joshua Mezher

For whatever reason, the general opinion is that growing pot is expensive and complicated. We are here to change that notion. The truth is, it’s called weed for a reason and we want every gardener to grow it as though it were another garden variety.  It is an amazing plant to share space with. It may have even been humanity's first companion plant. Not many plants grow as vigorously, express such a variety of smells, display so many different shades of the rainbow, or heal the body while calming the brain.

What You Need to Grow Weed Indoors and On a Budget

Those are the bare bones of growing weed cheap! There are several other accessories you can use to help produce the best yield possible and aid with clean-up, including a watering can fabric grow pot, saucer, and natural leaf shine. This can be an expensive toolkit to put together on your own. To save money, you can check out our complete grow kits at a Pot for Pot. We have everything you need to grow and you won’t have to take care of shipping costs from multiple websites.

Grow Room Requirements

When setting up your marijuana grow room, you need to follow a few grow room requirements:

The Grow Room Must Be Lightproof

Designating the amount of light and darkness your plants receive is very important for an indoor grow room. By making your grow room lightproof, you ensure that your marijuana plant can get 18 hours of light and six hours of darkness.

Another reason you need it to be lightproof is that as your plant matures, you’ll have to adjust the amount of light and darkness the plant receives. If your room isn’t lightproof, this can disrupt the growth cycle.

Your Grow Room Needs an Air Management System

A grow room needs air management to control the heat from the grow lamps and the stench of the plants. Grow lights give off a fair amount of heat that can damage your plants if it isn’t ventilated. And as your plants grow, they can smell quite strong with can be an offensive odor to neighbors or houseguests. 

Several solutions can do this, but one of the easiest ways is to install an air extractor with a filter. An air extractor can absorb the heat and smell without expelling it outside.

You’ll also need to find a way to provide more air to your plants. Most rooms have 250 ppm of carbon dioxide, but your plants will absorb this very quickly, especially if your grow room is small. You’ll need a way to get more air to your plants without letting in light. You’ll also need a fan to circulate the air throughout the grow room for even air distribution.

The Grow Room Needs a Waterproof Floor

Your plants will need water and eventually, water will leak onto the floor. To protect your floors, you’ll want to ensure that the plants are over-waterproof flooring. This can be tile, plastic, cement, or rubber. 

Another reason you’ll want waterproof flooring is to create humidity. Spraying the floor with water will help increase the humidity levels in your grow room. Extra humidity also creates moisture that will damage your flooring if it isn’t waterproof.

If waterproofing floors just seems like a major hassle, skip it and just make sure that you have a saucer under your pot. 


Reflective Walls will Also Benefit Your Plants

One more thing to optimize your grow room is to have reflective walls. Reflective walls amplify the lamp’s light to help increase the plant’s yield. White or metallic walls will reflect more than black walls. A grow tent is an excellent solution for creating an optimal growing environment, but you can also line your walls with tin foil.

You can create your own grow room relatively cheaply using DIY materials or a grow tent. Once your room is ready, you’ll need the right equipment to give your plants the best chance of developing strong.

Grow Room Equipment for Cheap

When equipping your grow room, you can do it bare bones or increase your yield with measurement and control tools. Either option will work, but the more you invest, the better quality your plants will be. Here are the essential tools you will need:

Indoor Grow Lamp

Whether you’re building a basic indoor grow room or an upgraded room, you need high-quality lighting. When outfitting your grow room, you’ll want to buy the best lamp bulb for your budget. There are three types of lamps that work best indoors for growing marijuana: 

  • Compact Fluorescent Lights (CFLs): Fluorescent lights are great during the vegetative phase because they emit little heat and are very energy efficient. Unfortunately, CFLs don’t cover the full UV spectrum, so they aren’t the best lights during the flowering phase. A cheaper option, you can expect to grow about an ounce of pot for every 100 watts.
  • High-Pressure Sodium Lights (HPS): HPS lights produce the full UV spectrum for all growing phases. These are the most powerful lights which can boost growth. A big con to HPS is that they aren’t efficient and can increase your energy bill significantly. They also produce a fair amount of heat that will need a management system, or the heat can damage the plants. HPS lamps can produce about three ounces of marijuana for every 100 watts.
  • Light-Emitting Diode Lights (LED): LED lights can produce the right spectrum of light for all growth phases, and they are very energy efficient. LEDs can be more expensive upfront but can save money over time. Another con to LEDs is that they aren’t as powerful as other options. LEDs can produce about two ounces of marijuana for every 100 watts.

Depending on how many plants you are growing, you may want to weigh which lamp will be the best option. CFLs are going to be your cheapest option but won’t produce as much as an HPS.

The Importance of Grow Lights for Cannabis Cultivation

The more light you have the bigger your yield is going to be.  Think of it as the engine, the bigger it is the faster you can go.  While lighting for cannabis is a highly debated subject, our team at a Pot for Pot believes that the best form of light for your plants is the sun.  First and foremost, it is a giant fireball in the sky that is free! Not to mention it is a true full-spectrum light source that the plant evolved to grow under.  

A sunny window with 4 hours of direct sun will grow a couple of baggies. With full sun all day, you will send your yields through the roof. But having too much pot has never been a problem.  If you live in a house that gets very little direct sunlight, you can always supplement with a natural spectrum COB LED grow light. These lights are affordable to buy, have low energy costs, and emit a natural spectrum of light that can proudly sit over your cannabis plant in the corner of your living room.

Ensure You're Working With Good Cannabis Soil

The better the soil and the more light you have, the better your plants will grow.  We tailored our home grow box to include everything you need to go from seed to harvesting your own organic flowers, at a price that won’t leave you stressing over the thing that’s supposed to relax you.  To make it easy, we blend over 18 different ingredients into our Superb Soil so that it provides all the nutrients needed to go from seed or clone into a beautiful budding plant. 

Thanks to Plant Success Organics, we are also able to include their Great White Mycorrhizae and Mycos Chum Nutrients.  Their premium beneficial bacteria & Trichoderma work in symbiosis with your plant's roots to break the soil down and maximize your plant's nutrient uptake. Over 10 years, I have grown in everything, and at the end of the day, nothing beats the smell and taste of naturally soil-grown cannabis.

Other Equipment that Can Boost Your Yield

Aside from great soil and lighting, here are a few more tools that can enhance your plant’s growth:

  • Reflector: Directs light on the ceiling and walls back toward your plants.
  • Ballast: Controls the energy used by your lamp to reduce energy costs.
  • Time Switch: Automatically manage your light schedule by turning the lamps on and off based on the cycles you set.
  • Air Extractor: Pulls heat from the room and helps manage the smell of the plants.
  • Carbon Filter: Neutralizes the odor from the plants.
  • Air Intake: Helps circulate and pump fresh air into the room to enable plant growth.
  • Thermostat Controller: Regulates the air extractor to help maintain an optimal room temperature.
  • Rotating Fan: Rotates and circulates the air for an even distribution of CO2 to all the plants.
  • Hygrometer: Measures the humidity in the room.
  • Thermometer: Measures the temperature in the room.
  • Water Tank: Helps to make the nutrient solution.
  • EC Meter: Measures the nutrients and minerals in the water.
  • pH Meter: Measures the pH levels in the water to perfect the balance.
  • Watering Can or Pump: Helps water the plants.

All of these tools can enhance your growth, but it might not be feasible to buy all of them on a budget. All you need is a head on your shoulders and a dash of motivation.  What you don’t need is a grow room, a grow light, or even a green thumb.  With just a bit of sun, you can enjoy the journey of harvesting your own homegrown. The truth is, if you are one of those people who kill plants, that’s just because you never had a plant worth caring about.  By using our kit combined with auto-flowering cannabis seeds, all you need to do is add water, sunshine, and a little love.
