Grow lights can also help you alter the lighting schedule to encourage flowering, but that’s something you don’t need to worry about with auto-flowering seeds, which is the variety we encourage for first time growers. When growing in a windowsill, choose auto-flowering plants, since you won’t need to alter the amount of light to induce the flowering phase — those plants will grow no matter what.
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.
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.
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.

Your marijuana plants need enough light to grow, and generally, 3-4 hours of direct sunlight is the minimum needed. A windowsill will typically give them enough to do it effectively. Grow lights can provide higher yields, but natural sunlight has been doing a great job since long before LEDs were invented, and it’s totally free!
Even when growing with lamps indoors, a single marijuana plant can yield a whole pound of weed with the proper growing techniques. Clearly, less is the most cost-effective option!
Growing Marijuana Costs
You really don’t need to grow a ton of cannabis plants to get enough weed. If you keep it small, there is no reason growing marijuana should be expensive.
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.
Marijuana is the botanical conversation piece that just won’t go away. Reactions to it run a wild gamut: It’s the evil weed or a source of future state tax revenue and entrepreneurial ingenuity. Or it’s the only path left to freedom from pain for some people, and journalists should write about it with the same seriousness that they accord blood-pressure medicine.
But if you’re trying to get six plants to be as robust as possible, you probably need to install something that’s more permanent, like a 400- to 600-watt lamp with a hood assembly that comes with a ballast, which you place at least a forearm’s length above the plants.
