Do you need help identifying a 🌶?
Is your plant suffering from an unknown issue? 🤧

Not Extremely Impressed with T5 Bulbs

When you crank the T5 fixture from 4 bulbs on to 8 bulbs on, it's quite a difference. The plants look great. The Baccatums seem to need a ton of light to thrive.

Chris,
Â
How have your T5's held up over these years? Are you happy with them?

Is most everyone growing the seedlings just 2 stick outside in the spring?
While bright, I'm not so sure a T5 could produce fruit on plants either. Don't get me wrong...my plants are pretty healthy under it, but not super stocky. I've been a bit lazy this year about potting up too. I'm still happy with my seedlings though for the most part.
Anyone else have opinions who have tried both?
Chris
I have been fruiting brandywine, taxi, and oregon spring tomatoes under (12) 6500k T5 bulbs in two different fixtures.
I have not had any problems with lumen output so far. Perhaps you are running used/old bulbs?

Do you find the T5 fixtures to heat up the growing space a lot?

This lighting system is situated inside a 4x4 grow tent.
I am running full climate controls with fan speed controller, so I really am not bothered with light temps.
I maintain 68% RH at 76° lights on, 75% RH at 68° lights off.
Without blower the tent would probably be close to 85+°

Hmmmm.
20 or so watts per bulb more than a T8, my 6 bulb by 4' T5 works just fine from first potting to plant out, and I have Reapers, Moruga's, Peach Bhut's, Bolivian Rainbows, Chocolate Habs and Inca Berries with pods on plants in pots over a year old for my winter grow.
Â
They are manicured to produce under these lights, but in all honesty, really good for a couple months from seedlings---not suitable for full grow of large plants.
IMHO, 2 more 6 tube T5 would do it, but then you are aproaching the same cost in electricity as a 1,000 watt MH, and a much higher cost in equipment.

I love my T-5 HO 6 bulb fixture. I can turn on 2, 4, or six bulbs. Love this fixture. Highly polished reflectors too. Can't wait to automate it.Alphaeon said:I am in the ++++ on T-5 group1x 6 tube fixture worked great for me. Ordering another for next year
This is the fixture I have. I love it. When I get my tax return, I will be getting another one of these.

I have a 2 foot T-5 HO 2 bulb fixture for my seedlings. It is great.
