Does using both types of lights make a difference?

[ghost83]

So I was watching a documetary on growing the other day and they were talking about using MH and HPS lights for the plants durring the flowering process. They said that the plants get a wider spectrum of lights and will develop thicker denser buds. My question is...has anyone tried this and if so does it really make a difference? I am using CFL lights because I am growing in a small area and dont want to worry about heat issues so I would be using the 6500K and the 2700K light bulbs.

Thanks for any help or comments

I have often wanted to try this but never had the equipment available at the right times. I am doing exactly this now though , the wider spectrum should make some noticeable difference. <we shall see huh? >

There is always at least 1 6500 in my flower boxes. I don't overload the plants with it, but they get the spectrum, and my plants are constantly turned and rotated, so every part of the plants get some time with it each day.

Crap, sorry I didn't answer the question - I have nice, thick, sturdy stems - I've seen others have week and spindely plants, so I'd like to say yes, but this could be attributed to many variables. I've never flowered without full spectrum, but I've made several other mistakes!

I decided to try it anyways. I still have more 2700k light bulb the I do of the 5500k. I dont think they are growing at a faster rate but I do feel like the crystals/tricombs are coming in quicker then they should. But then again it is just a CFL grow so we will see what happens. Like I said in my grow log...I am hoping for about 1-1.5 oz from each plant

Love the idea, but I thought you were talking about MH HPS not CFL.

Using the 2 CFL lamps cannot hurt.

I used to use my 400w MH high bay lamp (my veg lamp), and a 250 watt HPS (my side light) in the grow room before I got the 1000w hortilux set up. You will like the results.
