I am finalizing my grow room design and thinking about using T5HO fluorescents all the way through to harvest. I know it is popular to veg under 6000K fluorescents, but I am hoping to hear from someone who has flowered with 3000K T5HO bulbs. The idea of lower heat production, not having to purchase additional fixtures, and change lighting midway through are very attractive to me. I am trying to be very stealthy in a 8x4x7 attic space, so heat and electrical consumption are getting big priority. On the other hand, I am looking to get a nice yield with a short turnover cycle. Planning on using the SCROG method with an ebb/flow or aeroponic system. 6 plants on first grow, but expanding up to 24 as I perfect my method.

I use the cool fluorescent (6000k) for veg. I flower under mixed spectrum HID (1000HPS and 400MH). Ive read of excellent results using T5's for the entire cycle. You and Six are right, to maximize light penetration thru the canopy, utilize the screen of green method.

Youre going to be vegging and flowering in the same space correct? You could use a mix of both warm spectrum (3000k) and cool (6000k) for the entire cycle. For example if you had the 8 bank ballast, use 4 warm and 4 cool. That way you could avoid having to switch out lighting.

Another option would be to utilize multiple ballasts. Load some up with cool and some with warm. Use 1 powerstrip for each spectrum then when you switch from veg to flower, you can change spectrum with a flick of a switch.

Im no expert and dont have a ton of technical details of light spectrum and plant growth. I just wanted to share some thoughts that came to mind while I was reading your post.

Good luck! I look forward to pictures.

2650-3200K – warm white (yellowish-white)
3200-4000K – neutral Above
4000K+ – cool (bluish-white), also called "daylight"

I use t5h's for the entire grow, during flowering I add blacklight for extra uva/b which increases the amount of THC the plant produces, it won't however make the plant grow bigger but the bud it does produce will be of exceptional quality.

t5 is good fro grow but does it have the right spectrum and you want to use warm colored light for flowering

You get about twelve inches light penetration out of the T5HO keep them tied down in a sea of green.

Could you elaborate on this a little? How much wattage as a % of the total do you have in blacklights? How far along in the grow do you switch them on? And realistically, how much of a difference in the bud is there? Can the people you smoke with tell the difference too? I wish we could get uvb by breaking the outer bulb on an hid, but it will just kill the plant with uvc..

Ive seen on many occasions that using the T-5 set up with both veg and bloom bulbs from the start, have a tendancy to cause rediculous streching depending on the strain. I use an 8 bulb set up with all actinic's and after 3 weeks they do shoot up and I will super crop them and fem or top them as well. Unknowingly I had a sativa get up over 4'-4.5' before forcing it into flowering. 6' under these lights is not unheard of if you keep them vegging with no restraints. A t-5 set up from start to finish if done right can yield handsomly and is the easiest set up ever.
