Da1,

The main problem with the CFL you are using now is in the light spectrum they produce. You can compensate for the limited spectrum, to a degree, by using MORE oif what you already have.

The bulbs I have are 5500K and 6400K CFL.

The output of these bulbs are simply enormous.

I have seen some really good grows with the long tubes but you gotta have MORE of them. Your lights will work, but, you need a shitload of lumens from your CFL.

I would prefer the CFL you are using now over the long tubes, but, youre gonna need a shitload of them.

You wont grow bushy plants with 42W of CFL.

In fact, I have a 250W HPS unit I bought for $100.00.

HOw about you pay for shipping and I just give it to you.

I even went to Home Depot and bought a brand new 250W HPS bulb for it, still in the package.

They are both yours.

Email me your address, if you want...

pay for shipping and the setup is yours.

HAPPY GROWING!
