What is the investment income of grow cannabis indoor?

Growing indoors doesn’t have to automatically be expensive, especially if you plan it right. You can use led grow lights on your plants so they don’t use extra energy (and therefore won’t cost you extra money). The key is to keep your growth operation small since that will take away the necessity of installing a carbon filter (since the smell won’t get out of hand with just a couple plants) and other pieces of equipment.
Altogether it shouldn’t cost you more than about $80 -$200 to get led grow lights, a small fan, some pots, soil, and the seeds. Some people especially good at DIY projects could even reduce that cost further. Even if you want to “level up” and use a more professional grow system, it should only cost around $350.
Grow lights get hot and growing cannabis indoors requires the temperature to be regulated. Fans are a huge component of an indoor grow and can cost up to $100 or more per fan. The larger your grow operation, the more fans you will need. For a large-scale grow operation, you could be looking at startup costs for fans at $1,00 or more.
There is also the cost for humidifiers and ventilation systems. In order to keep plants healthy and happy, you’ll need all the equipment that makes up an ideal environment. On average, the cost of fans and other equipment you’ll need can run $1,00-$3,00
Yields
Of course, everyone wants to know the return they could get from investing their time and money into this project. In the marijuana growing world, this “return” is simply the yield. If you’re spending a lot of effort keeping your plants happy and healthy, how much weed will you get from it?
The main thing (besides the seeds themselves) that you’re going to want to think about is the grow lights. This makes the most significant difference in the yields and growing patterns of your indoor marijuana plants. If you’re an experienced grower, you may be able to expect a gram of weed per every watt of light you are using. So, if you have a 400-watt HPS grow light, you could get around 400 grams of marijuana (which is about 14 ounces).
If you’re a newer grower, the yields will most likely be a little lower. Still, in a grow closet or cabinet of 3.5 by 1.5 by 6.5 feet, you could get 1.5-2.0 ounces with 200-watt led grow light and 3.0-5.0 ounces with 250-watt HPS lamps. In a small grow room (3.5 by 3.5 by 7 feet) with a 400-watt HPS lamp, you could expect 4.5-9.0 ounces. In a “medium” grow room (4 by 4 by 8 feet), you could get between 5.0 and 10 ounces with a 600-watt HPS lamp, and in a larger grow up (5 by 5 by 8 feet) with a 1000-watt HPS lamp you will get between 9.0 and 18 ounces of marijuana.
Calculating Electricity & Water Costs For Cannabis Growing
In some sectors of grow-op home business costs, you have to take into account more than square-foot percentages. Consider electricity and water, for example. When I precisely measure the exact amount of electricity and water I use for growing my cannabis, I figure not just the dollar costs, but the ratio of use compared to my baseline water and electricity for other domestic needs. The simple truth is, if you don’t have a grow op in your home, you’re probably going to use a lot less water and electricity there than if you do.
Electricity and water costs vary by region, climate and season, so it’s important to keep track of how much of each you give your cannabis crop on a month-by-month basis.
It isn’t easy to do, because you have electricity costs from grow lights, fans, dehumidifiers and air conditioning, and at least some of the cost of powering such equipment is shared with the rest of the home.
If you’re running an unsealed grow room that doesn’t have its own air conditioner (in other words, the grow room is cooled by the same air conditioner that cools the rest of the home), you use the same kind of calculation as with the home office deduction, but you add to that the extra BTUs of cooling power needed to remove heat from grow lights.
Calculating the cost of air-conditioning electricity involves knowing how many BTUs of cooling capacity are being used just for the grow op, plus the cost of electricity per watt.
But I found an easier way to figure it out.
Before I built my grow room, I was living in the house where I eventually started my professional cannabis grow op. I knew what my electricity bills were for the months I grow indoors, from October to May, and I also requested from the electricity company two years’ worth of records for my home’s monthly bills.
After I established the basic cost of electricity per month without a grow room, it was easy to see how much extra I was spending on running a bunch of grow lights. For a typical October without a grow room in operation, my electricity costs were $67. With a grow room, it was $160.
In April, without a grow room in operation, my electricity cost was $53. In April with a grow room, the cost was $135. These comparisons help me estimate total electricity cost of the grow op per season, and also on a yearly basis.
I also took into account that grow-room heat offsets my heating costs during colder months.
Calculating water usage for cannabis growing is somewhat easier than calculating electrical costs. I can easily see how many gallons of reverse osmosis water I use when mixing my hydroponic nutrients solution. And I know how much water waste my reverse osmosis system creates. (For every gallon of reverse osmosis water, about 1.5 gallons goes to waste.)
Because I’m billed based on gallon consumption readings from the municipal water meter, I contacted the municipal water agency to find out how much each gallon is costing me, and then did the math.
