How much money do you need to start growing weed

If you use a hydroponics setup , you must purchase an inert growing medium such as coco coir or rockwool, and are also responsible for ensuring that your crop gets all the nutrients it needs. The cost of the system itself depends on the ‘type’ you choose. For instance, a 12-plant watering system could cost over $500, but there are cheaper options for under $200.

You can purchase seeds online for anywhere between $10 and $20 apiece. There should also be options to purchase 3-packs, 5-packs, and 10-packs at least. A 10-pack should cost 20% or so less per seed. A 5-pack is the most popular option (most states only allow you to grow a maximum of six plants) and will probably cost approximately $60.


With legal medicinal marijuana now available in 33 American states and D.C. , the industry is set for a golden age. In fact, there are so many commercial cultivators that states such as Oregon have a massive surplus. In 2017, the global legal marijuana industry was worth around $9.5 billion per annum; the United States accounted for 90% of it!

The Cannabis Business Plan website suggests that the average commercial operation has costs of $830,000 per annum! When you add in the heavy taxes on weed businesses, and difficulties finding a bank that will do business with you, cannabis-based businesses will find it tough to make their fortune.

Electricity costs are harder to calculate because the cost varies across the United States. The national average is approximately When you add in extra costs such as a hood and ballast, a 1000-Watt setup could cost up to $600. Hopefully, you can produce a gram per watt. This would equate to just under 36 ounces..13 per kWh. A 320-Watt LED grow light probably uses almost 6-kilowatt hours per day during the vegetative stage . In flowering, the same light uses almost 4-kilowatt hours a day. Overall, the cost of electricity for this single grow light is approximately $4 per week. For three lights and a 10-week grow, your electricity cost is $120.

The other good thing about LED lights is that they are cost effective. Using LED lights can save you money compared to Compact Fluorescent Lights (CFL). CFL lights take longer to become fully lit and can’t be dimmed, so they’re not very energy efficient. LEDs emit very little heat to produce the same amount of good light as HPS lights. You can produce a much larger yield with 5 marijuana plants in a 600-watt grow tent (see above) using HPS lights than with CFL lights in the same space.

Knowing how to grow a small weed plant is likely the hardest part of actually growing it. Now that you know what to do, you are well on your way to enjoying hassle-free, home-grown marijuana.

In many areas, there is a six-plant limit. If that seems small, keep in mind that with just six plants or less, you can still yield plenty. Plus, it is way easier to handle six plants instead of something like fourteen. This is especially true when growing indoors. Think about how much yield you can produce under a grow lamp. For example, using four plants under a 600-watt HPS (High Pressure Sodium) lamp will produce more yield than squeezing sixteen of them under that lamp.

The cost associated with growing marijuana plants can be a bit scary if you don’t know your stuff, but your new hobby really doesn’t have to break the bank. Even indoor growing can be quite affordable when well planned, and it is also a discreet way to produce high yields for both recreational and medicinal purposes.

One reason people like LED lights is that they tend to generate far less heat when compared to HPS lights. Because of this, your plant will use less water, which means they won’t necessarily need as much water or nutrients.

Avoid Common Mistakes

Let’s say you grow 5 marijuana plants in a 4×4 foot grow tent using a 600 watt HPS lamp. This will run the price tag to about $2000 per year with a yield of a single pound. That works out to about $100 per plant if you are harvesting 4 times a year.

As you can see, unless you’re growing outdoors, you simply get more for your money by using LED lights.

If a 6′ x 6′ ft space is unrealistic, consider growing in a much smaller space using a grow tent. Grow tent dimensions start at 2′ x 2′ x 5′ for under $1,000, which includes everything you’ll need to grow cannabis except for soil and the plants. You can usually grow two to four plants in 1- to 3-gallon pots, and you’ll most likely use a 400-600 watt light.

But growing your own cannabis does present some difficulties. Pests, mold, and other diseases can rapidly sabotage a grow and leave you with a bad crop. If you’re completely new to growing, trial and error could lead to some costly mistakes as you learn how to properly raise healthy crops with strong yields.

For this estimate, we are growing in a climate where plants can be outside from the start of the season (July) to the end of the season (October). Again, we assume using clones to start, which aren’t included in our cost estimates.

You can get high yields of quality product growing outdoors. A plant grown in a 10-gallon pot should net you between 1-2 lbs of flower. You’ll need to consider the amount of time you will put into your garden—a couple of hours every couple of days on average should be enough to take care of your plants. Some days won’t require any work while others will require a bit.

For our indoor cannabis grow cost estimates, we estimated costs for a 6′ x 6′ grow space, using soil as the growing medium, and only one room for both vegetative growing and flowering. Also, let’s assume we’re in a temperate climate where the use of A/C won’t be necessary, which will save some energy costs.

Cost Estimates of Growing Cannabis Indoors

With a 1000-watt bulb, ideally, you will produce up to a gram of flower per watt. Realistically, when starting out, you might get anywhere between half a gram and a gram per watt. This assumes you avoid pests and disease, and you feed your plants nutrients to keep them healthy. You should set aside an hour or more every couple days to observe your plants and work in the garden to keep your plants happy.

Growing your own cannabis has its own set of benefits and drawbacks. Taking cultivation into your own hands gives you complete control of what goes into your cannabis, and it also gives you full knowledge of the growing process and a better understanding and appreciation of the plant.
