Who's working with T5s

Doco:

Unfortunately you're speaking in absolutes, and you should not be.

Fact: the 48" bulb comes both as 54w and 28 watts.
Fact: not all T5s are HO.
That all T5 bulbs are HO, even for 24" is incorrect.

T-5 Lamp Miniature Bi-Pin Base 48" 6500K: Light Bulbs Etc, Inc.

Misinformation indeed.

err, umm, shuffles feet....I stand corrected.

But my bigger point was that your insistence on using 54w bulbs is not necessary...the 24" 24w x 4 tubes do just fine if you don't have room for the bigger ones. You always want to use as much wattage as your space can allow of course.

This Bubblegum has been 3 weeks of 12-12. Over 36" tall Lots of bud sites all over. This top in the photo is about an inch from a pair of 32W 3000k FT8 lamps and a 98% reflector. It has (4) tube by 46" 54watt T5HO 3000K.for horizontal side lighting. I used theses same fixtures to veg but used all
cooler tubes. When I went to 12-12, for more sidelighting I added these 250W HID lamps of some sort. Some older mulivapor. The way this grow looks, I think I'll try without the 500W of HID next time.

I'm glad I found this thread, haha! I'm contemplating buying either a T5 4' 4 lamp fixture, or a T5 2' 8 lamp system. The 2' system would def fit better in my closet, but the the 4' has higher wattage, and puts out 4000 more (overall) lumens. I'm curious if the 2' fixture would work jst as well, though ?

Anyone know?

The concern about the lower powered lighting source of the fluorecent lamps is that it gives light, "airy" buds. I've not grown excusivley indoors before, but I'm willing to give the tubes a chance because I like their numbers. I think that if I can get the vegitation close to the tubes I'm gold. :]

Seems that maybe these do support flowering very well. Again, just three weeks into 12-12.

i use a T5 for vegging plants...if you wanna look in my grow log (click my sig) i talk about it quite a bit in the last page or two.

Here is my mothering station. First pic is 12/24, second pic 1/12 - pretty good growth for 19 days. 24" T5 HO 24w x 4 bulbs 6500 K. There are also T8 6500 K tubes on the sides.

I have only started with this light a short while ago but I'm amazed with it.

Nice photos.

I see that you have fixtures both ontop and on the sides.
Are they all going at the same time?
Any heat issues?

How much height do you have? do you need?

My cab is 4' W and 6' H.
I think I will have a lot of wasted height which I might use for clones.
