Need to get me some T5's
This thread is for all T5 users to share their knowledge, problems, and Cannaporn
There seems to be plenty of T5 growers on the site, but no real organized knowledge base.
There is plenty of potential in the lights, let's see your methods,
and of course results!
So welcome to the Official Club T5 Thread!!!

This is from my Multi spectrum grow. The idea here is that you bud and flower under the same light.
So you only have to change the timer from 20/4 to 12/12. All the light they need in both vegging and flowering is here.
I used a flood table and the full grow journal can be found im sig. (total grow stats first entry)

I just got my T5 hung up in my cabinet, I decided to not use the rollers, and just hand the metal V hooks directly to the J hooks.
Right now all I have is one skinny vertical plant, so most of the light spread is being wasted..
Eventually I plan on keeping a perpetual going.
I've got 4 clones rooting right now.
rocking a 2' 8 bulb t5 in my dr60 loving it so far. Except it takes up ALL the width and length space in my tent and heat just chills in there...
I like the idea of us having a home where we can commiserate. I'm a fan of T-5 lighting but far from an expert. My last two medical grows have been under a four tube rack of T-5's and I have to admit I'm happy with the results. I was advised by one of our instructors at a local hydro class to try a progressive light schedule starting with 20 hours on and 4 hours off for the first week and then drop the light by one hour a week, each week. This increases their dark resting period by an hour each week and the result was my plants began flowering on their own at approximately 14 to 13 hours of light. They didn't wait for forced flowering at 12/12.
When I noticed pre-flowering occurring I changed from the blue veg lights to the red flowering tubes and I transitioned my plants to a 1/2 strength flowering nutes formula. The following week I changed their nutes again and fed them the full strength formula and the fun really started. I would encourage anyone interested to try it. If your plants are surrounded by a good reflective surface you can get buds all the way down to the planting deck.
You can sit T-5 lamps a couple of inches off the tops of your plants even though the manufacturer recommended a height of 6" to a foot. I don't know that you can do that with any other lighting system without cooking your plants. There's no real heat to deal with.
My only criticisms are that you can only grow directly under the fixture and you won't get buds as dense as the folks using HID lighting. Yours will be softer but their anesthetic effect will be just as good as any one else's. My fixture is approximately 15" wide by 4' long. It covers two 10' by 20" starter trays set end to end nicely and later my two ten gallon bubble tubs end to end but anything beyond that area isn't going to get enough light.
My suggestion is that if you're going to use T-5's and you know you're going to be limited to the immediate area underneath the fixture, don't waste your time and money on two tube and four tube fixtures. Spend the extra cash and purchase a six or even eight or ten tube fixture long enough to cover your intended grow. I wish I had.
Additionally, compared to almost every other lighting system on the market, they're cheap to run. That's my two bits worth. HSA

very well said. some t-5s put out around 95 lumen/watt which is much higher than even an HID
my T5 was finally delivered yesterday, so ill be posting pics in a few weeks. Its 4ft 4 tube hydrofarm. I was very impressed with the output , as i was skeptical , but it is really bright . Now to see how good she grows.
