Checked out your grow, nice plants.
bulbs I use are ,,,
GE 4100K
Plantmax 6500K
ATI True Actinic
ATI Coral Plus
thanks, if i go with the t5 light thing, how many of each?? and should i throw in a couple via volt 2700k bulbs just to add some red spec for flower?? looking at your set up, im impressed and confused as i was always told its the red spectrum that increases bud size however ur buds are quite massive under very little if any red..is the red spectrum really not as neccessary as i was led to believe??

Also i forgot to ask, how often do you replace the bulbs?? are they like mh/hps were u must replace them every 6 months? or can you get a year or more out of them?? sorry about all the questions but if im going to do it id like to do it wright... how far above your plants do u keep the fixtures?? or are they mounted to the ceiling and you raise and lower the plants??

@RM3 Don't you find that running all those T5 is hot and draws a lot of juice? Don't use T5s @TheChemist77 they are probably the worst source of lighting of the major 3 sources (HID/LED/CFL) they make a ton of heat and don't give you hardly any light intensity. For side lighting a t5 might be ok but even then you're just increasing heat for barely any return if anything, with my 600w hps on I can't even tell if my t5 is in the room with it cause the HID is so much more powerful. T5s are mostly only good for rooting clones.

i have a bc nl bloombox and in it it has a 400 watt hid above and 2 2 ft t5's below and they work wonders.. ive also used t12 for under lighting in my bloom room, and found the t5's were 1000 times better..i know hids put out way more lumens, lumens=penetration so ur point is valid..i just found RM3'S grow to be really cool, and guy is pulling weight out of there,u gotta respect that. im not going to run all t5's, but i may add the ones i have next to my 2 600 watt hps to add some blue spectrum.. maybe in the future when i can aford the 6 or 8 bulb fixtures ill run a side by side compare as using the t5's is using alot less watts than 2 600's..hes running roughly 600 watts for a 5x5 area wile im running 1200 watts in a 6x5, so hes useing half the watts and only 1 foot less than me..ive always used mh for veg and hps for bloom, but i wonder what addinf some blue spec to my room will do?? i am also considering insted of running 2 hps using 1 mh and 1 hps or using both 600 hps and adding a 400 watt mh but that maybe using overkill for my area and my electric bills are already $700.00 a month.. but im running 3 400 watters, 2 600 watters and 2 250 watt cfl's pluss all my pumps and 2 2ft t5's and 4 4ft t5's,, i need to cut costs somewhere or in summer adding the A/C will kill me..

No and 1000 watts is 1000 watts and honestly it won't be long before more growers are usin em, I know 4 that have changed over in just the past few weeks

It amazes me how many people don't understand that. All electronic devices are 99.9999% efficient at converting electricity into heat. Only loss is light or sound that escapes your enclosure. Otherwise once absorbed it turns to heat. A watt truly is a universal measure for heat output of an electronic device.
