T5 lighting

The Newwave T5 4' 8 bulb 6500 is so awesome when it comes to veg. I have never seen plants with such close internodes and bushy. Flowering is another problem. There is no way that the light can get in below the canopy even if it is kept about 2 inches away. For those that are going this route of T5's alone, don't do it. I actually had to add 2 more single lights to the sides just to get more light. For those that tell you that you can veg with 6500 and bloom with 3000 under T5's, don't try it! Keep to the HPS for bloom.

I've been pretty satisfied with mine so far,but this is my first T5 and only about 2 weeks into flower.

yeah t5s rock i think with a little work u could get some fine buddage wit dem floros but hps is some much easier with mine ima always wantin my sunglasses i know ma babies r gettin plenty of light evan vegetive prefer mh lt.

thats a exellent grow room KW :thumbsup: nice plants 2 whacha growin?

An indica dominate strain thats called Hurk. It seems to be pretty easy to grow. I'm still trying to come up with a good sativa strain.

agreed. I think it should work unless you are trying to yield a pound per plant :wtf:

Spectrum schmectrum.

Plants will bloom the best under 2450K light whether its T-5 or not. They do the second best at blooming under 2750, T-5 or not. 90% of the cfl grows are done at 2700K exclusively, which usually produces fine results. That's not that far off from your 3000K bulbs, but turk is right that 3000 isn't ideal. It will however produce bud, you just need more lumens. So why don't you not buy 3000K lights, and get 2700K or better yet 2400 or 2500 (if they exist).

These 3 combinations will yield about the same assuming all else is equal:
- 6000 lumens of 3000K
- 4000 lumens of 2750K
- 2000 lumens of 2450K

2750K has a chlorophyll response roughly double that of 3000K, and 2450 has a chlorophyll response roughly double that of 2750K. I'm not pulling those numbers out of my ass. Check the charts. So to say it won't work is kinda silly in my book. Yes of course the correct spectrum of HPS, will do much better than an incorrect spectrum, or wavelength of fluorescent, which is what turk has going on.

killerweed, pretty cool set up you got going there.

Yeah I thought I'd try something a little different. And I got each lamp with bulbs for $100 each. Mine has 8 of the 3000k bulbs in each lamp.

1) what K are the CFL?
2) are you doing a log?
3) why 3000 instead of 2700 or 2500, and please don't tell me it's because they don't make them. I just bought some T5 grow (6 thousand something K), and I just assumed I would later be able to put in some bulbs that are the correct color for budding. If not, I don't even think I want them.

PS.
4) what's the length on those T5s?
5) how many lamps per light? looks like about 8
6) how many lumens per lamp, or how many per light total?
7) a hundred damn bucks? Is that deal available to me and if so how?

Well, here's a silly answer to go along with my silly question you say I have. The T5 4foot light has the option of 6500 or 3000. Nothing more.

That's not a silly answer. It answers that question perfectly. Crap, now I don't want them. If what you say is true T5 lighting sucks. Don't buy any unless you want it only for veg. Didn't I kinda hear that someplace before?

1: The 8 CFL's are 42watt 2700k
2:No I haven't been doing a log on this grow.
3:I only had 2 options when I bought the system 5000k's or the Spectralux 54watt 3000k's
4:4 feet
5:8 lamps
6:5000 lumens per bulb,40,000 total
7" I bought them off hydroponics.net while they were on sale. I think they're $150 each now.

Thanks for the info guys. A real eye opener, damn it.

PS. Are you absolutely sure? No 2700 or something, anywhere?

I have seen 2700k's on the net but they don't seem to be the t5 High Output lamps. 20 or 30 watts so they won't have the lumens.

I can't locate anything other than the 6500 or 3000. If anyone finds any let me know. Until then, tucking fan leaves and rotating plants is the order of the day!

yup thats all i've seen the T5 in 3000k 6500k
the guy on ebay HTG has the agromax T5 bulbs good price if you 8
killerweed those are kool lamps excellent for side

T5 grow is over. Finished about 10 days early. Not sure why. It really seems like they quit growing about 2 weeks before that. I attribute it to the T5's as I never had a problem with HPS. I will send details of yield once it cures.
