Lights have fixtures and bulbs, and some require a ballast. Depending on the type and model, the bulbs or the fixtures can be more expensive. There are a lot of abbreviations, but don’t be alarmed.
The downside to CFLs is they aren’t great for flowering plants, and growers will usually use another type of light to finish plants. CFLs just don’t generate enough intense light for plants to pack on weight.
When growing outdoors you can harness the power of the sun, but in an indoor environment, sunlight is mimicked through the use of grow light bulbs, which aim to display the same spectrum of light as the sun.
Another consideration with cost is that some lights run hotter than others—HIDs, for example—so they may require additional fans or an AC unit to cool down a grow space. Extra equipment means more electricity, also driving up your utility bill.
Best HID grow light brands
HID (high-intensity discharge) is an umbrella term under which MH and HPS bulbs fall, which we’ll discuss more below. These types of lamps have a hood that reflects light and bulbs that are enclosed capsules containing a gas, as opposed to bulbs you’d find in your house, which have a filament that heats up.
High Pressure Sodium grow lights are often used during the flowering stage because they are very efficient and their yellow light stimulates bud production. HPS grow lights in the flowering stage get better yields per watt of electricity than any other type of grow light available today, which is a big part of why they are so popular.
If you get very high-wattage LEDs, you may need to vent out heat to keep the grow space cool
The light from an HPS appears yellow, and is great for flowering plants because the light spectrum stimulates bud production

Cons of Fluorescents
Keeping CFLs close results in the best yields and growth
Note 2: Incandescent light bulbs (old fashioned light bulbs) are NOT suitable for growing marijuana!
But, if you’re going for an HPS light at least, getting 1x 1000W will be cheaper.
Your nutrient-strength level is less variable when growing in soil than when growing hydroponically.
Nutrients When Growing in a Hydroponic System
In such a grow-setup you can easily yield 4 pounds (1800 grams) of smoke-able high-quality herb.
Now, if you’re growing in regular soil, you’ll definitely need a good set of quality nutrients.
Every plant has an optimal temperature level at which the maximum level of photosynthesis takes place.
