Hyroot, what are you pulling per square foot with the T5s and what were you pulling (per square foot) with the 1Ks? I'm talking dry/cured.
I'm asking, because I did look at your journal and the pics seem to depict very small flowers. That's not unusual for T5s, but highly unusual for 1Ks.

I guess for heat alone i will run t-5, thanks for all the input. hyroot which bulbs and where to get them?
Obviously you haven't tried them yourself otherwise you would know the truith.........
No, hyroot has a bit of missinformation... I just switched from t5 veg to mh. Big difference.
Not my first grow brother... just been growing indoors for almost a year. Just use the t5 for clones now.
honestly per watt and sq ft i pulled the same but the quality of t5 far surpassed the hps ones. the buds were the same size . the t5 is less tha half the wattage. if i matched watt for watt the t5 would blow away the 1000w. those were not small buds, the smallest one dried weighed 2 g. the biggest weighed 8 g
Not per watt, per square foot. You claimed that you pulled the same under 1K as you did under T5s. I find that to be, well, astonishing. Really. There can be a reasonable explanation for it, if you were using a magnetic 1K ballast. Other than that, all things being equal, I can't see how such a thing is even possible in practice. FWIW, to give a point of reference using myself as an example, I pull an average of ~3.25oz dry/cured Grade-A bud for every single square foot of my room under 1Ks.
I run 600s, as well. They pull less - ~2.5ft2 dry/cured on average. Here are some examples:

i use all quantum for hid and t5. but you got some very beautiful girls though
my last under the t5 i pulled 309g dry
3 x 4 and its because high par spectrum. The bulbs I use put out 70% to 80% more usable light than hid. was very skeptical first. But after the results I was so happy.
I have leaves grow onto my tubes pretty often, and they dont even burn they just light bleach the leaf surface that was touching but the leaf will usually live on. They can put a white stripe across an entire fan leaf but the tips will stay green and still thrive. equivalent wattage of HID light can fry a top in minutes if not checked.
I have no issues vegging with a T8, cheep ass light from home depot 6 bulb, I ordered 200 dollar 12 bulb T5 from fle bay that did not show up yet. How much do the T5's with all the diffrent bulbs cost? I started out cheep,and upgrading as I go.
That's less than an ounce per square foot. Not bad for T5s, but hardly impressive for someone who wants to harvest bud. One can only assume that you pulled the same under 1Ks, given the comparison you made earlier. I probably don't have to tell you how poor that is. I'm not trying to be rude; just hoping to put things in perspective. It's great to sit around philosophizing about the right spectrum, PAR and whatever else we don't fully understand, debating in a vacuum. However, cultivation is an applied pursuit. The results speak for themselves.
For example, I recently tested a pair of Digilux 600MHs. They measured very well, had a great spectrum, they came highly recommend...yet...they were responsible for the absolute slowest growth I've ever seen in my garden, aside from T5s and smaller MHs. That's the bottom line.
Why in the world would you want the branches to grow into the HID lamps?

lol, uh not many people. for obvious reasons. does it happen occasionally, yes. If you're trying to maintain the perfect balance of being close enough to get the most photonic energy, but far enough not to burn, you've only got X amout of space to play with. If you have one plant that gets away from you and takes off more than others, or shit happens and you gotta leave em alone for a day or two... is that a problem for a professional grower who knows everything about the strains they're growing and has CO2 and the perfect environment, probably not as much as the average joe who has come home after a double shift to a top that has gotten a bit cooked...
not a big problem if using T5's... sure if a growth tip sits right on a T5 bulb, those tiny developing leaves would be stunted, but it would just split like it was topped, the T5 wont dry it out down to the stem and stress the whole plant like an HID would.
So, the small lights are a substitute for grower competence? LOL!
