LED Without LEDs -My First T5 Grow

Contact them. They know which batches had problems. Batch ID is on each bulb. If yours is one of them, they will probably replace without you sending the bulb back

I use both Red Lifes and Florosuns. The Red Lifes are much 'redder'. more pink actually. I would 'think' there is more useful red in the RL, and since that spectrum is desirable during flower, I would want 2-3/8

I had 3 redsuns, 2 coral waves and 3 flora suns, but one redsun burned out. So I decided to go with a flora sun. To.distribute tye 660nm evenly. I will email them too. If I can get free one. could b backbup for later.

Just heard from UVL. The 660 will retail @ $19.95.


hyroot, OR... see if you can exchange it for a 660. Tell Jeff if he exchanges for a 660 that you will post updates in my journal. I'm guessing that it is best in 1/6

I have been running 1/8 9with 3 UVL Redlifes/Suns. I would like to see whether 2/8 is better, but that's a test for another grow. In the mean time I have increased the number of floodings per hour and today increased ppms from ~ 1000-1200. I am pretty sure this strain will love the additional ppms. Also am now flooding every 15 minutes during lights on.

You should come take a look at how I am pushing the envelope in my journal

Pet. Do you know when they are supposed to hit the stores?

Oh and Ive been talking to Ben at Hydro hut (pro grow) . Considering maybe getting a panel. I asked about how 2 180's would do. He kept pushing the 400 for same area. He would discount the 400 .

This update came in a couple hours ago from UVL

660s now available @ $19.95

From what I am seeing ith 1/8, I would like to try 2/8

Did they say through whom? Did you ever hear anything about that fiji spd by the way? I thought they were going to hook us up with a chart.

I was not involved in the Fiji thing.

Just order the 660s from your fav vendor

I would like to get to the bottom of this fact or fiction wavelength debate. Has anyone done any real testing with 420nm vs. 460nm to see which is more beneficial or not necessary? I've heard mixed messages when it comes to this debate. It doesn't seem like there is a clear answer. Lately, I've heard that 420nm is the preferred wavelength.

I do know that the Hortilux Blue MH lamp has to be the best lamp out there for growing. I've only seen great results growing with the Horti Blue. I do know that the lamp contains much lower blue wavelengths down into the 400nm region so could this be the answer? I do know that this lamp has more 420nm than 460nm. It seems the 460nm may be of less importance than the violet wavelengths, 400-420nm. With this being said, I would like to see some side by side comparison between using 460nm and not using 460nm. Has anyone tried combining lamps only using the UVL super actinic for the blue light? Anyone tried mixing only UVL super actinic and UVL red suns yet? Results? I only want tried and true proof, not opinions. The web is full of opinions and not so much actual fact, so please do not quote some science webpage or opinion from someone else because all that matter is facts, tried and true experimentation with photos, etc.
thanks for your input
