A look at some of my indoor Grow Lights and which I prefer.
Be they T5 tubes or CFL or even LED they will all grow plants well but which are best suited to your needs.
Personally I prefer the T5 lights as they are cooler than some of the CFL ones and can be placed closer to the plants without any risk of scorching.
If you only have a small space to cover then a larger CFL lamp would suffice, or even a smaller T5 tube light.
But even the tiny CFL bulbs and small LED panels are beneficial above your plants as they will increase the light levels and make them grow better.
