This will help you estimate how much yields to expect from your CFL grow, but you need to remember to take this with a grain of salt 👍 A very general rule of thumb is to expect about 0 😉25g/watt of CFL light if you use plant training and don’t run into major plant problems 🙈 This is counting CFL true watts, not any type of “equivalent” watts. CFL growers get better yields than the pros. They can achieve up to 0.25g/watt but that is for advanced growers. For beginners, you can expect to grow cannabis at 0.25g/watt. 
If you’ve ever worked in an office, then you’ve probably noticed that the fluorescent light bulbs above seem to always burn bright consistently. Although they eventually stop working, the fluorescent light bulbs have a significantly longer lifetime than those of old. One big benefit to fluorescent lighting is that it doesn’t produce nearly as much heat as the old light bulbs, making them ideal for providing artificial light for plants.

You will find all answers to your questions about CFL lamps and how to choose the right CFL grow light. Fernanda Stearns, Zibo (China) edited this page 73 days ago. 
Two ounces (60g) of cannabis retail value per plant: It is possible to get more, but it’s reasonable for anyone who follows the instructions. Each plant should yield at least two ounces dried marijuana. At $10-$20/gram (prices around here), two ounces of cannabis is equal to $566 – $1133 which is worth much more than the money you need to put in to get started. You will see a decrease in your investment each year, and a rise in yields. Plus, you don’t have to go anywhere to get your buds! My first marijuana plant that I grewrown with this method yielded 6.2 ounces dried buds. (See the flowering section below). Kinds of results you need to train your plant and invest in more CFLs as the plant get bigger to make sure there aren’t any shadowy areas. Modified by Lameka Mead, May 18, 2021 
A cannabis grower has many advantages. Important decisions you will make other than choosing the right seed bank is identifying a reliable lighting system. CFL, or compact fluorescent lighting is the most efficient and cost-effective. Professional cannabis growers use high-pressure sodium grow lamps (HPS) or high-intensity discharge lights (HID), in their indoor plants for many years. Although the light offered by these lights is strong and full-spectrum, you will still need to pay a lot of electricity. Powerful for the plants. How can you help?
