Mahalo for the vote of confidence, but I'm not a pro at anything.
I used to was a wiz at electronics and computers, but now antisocial insecurity pays me to kick back.
Guess that makes me a professional goof off.

My amateur opinion is;

Go with the t5 until the are past the stretching phase.

It's very hard to start 'lings with leds.
Most folks keep them too close and fry their plants, then claim that leds don't work.
Most commercial leds have a too high R:B ratio and will cause major stretch regardless of distance
Adding blue does not help, unless you back way off on the red.
I found it tricky, and being cheap and lazy, just threw a CFL at them for the first week or so.

This last batch are getting sunlight, with an LED array in the evening just to lengthen their day and keep them in veg.

Our tropical nights are a tad long and Indica's bolt to flower straight away without light extension.
Thinking about just giving them 2 hours of LED in the middle of the dark cycle so I don't have to keep resetting the timer as the planet wobbles.
(Did I mention lazy?)

Google "Discussion of the pragmatic application of LED's"

There's some good stuff there.
Aloha, enjoy
