I'm not into paying good money for lighting then paying to run a heater as well, if your in a cooler climate you'll be happy with the heat from hid, atm I'm toiling to maintain 25c above the canopy and 20c below it where the inlets are.

Fluorescent light are OK for seedlings or rooting clones when there's no rush, they're so slooowww lol give me a mh any time.

I think my led will be good for vegging where constant air exchange isn't so vital, it's low operating temperature isn't always welcome, horses for courses.

I've run MH, HPS, LED and Flouro for veg.. Flouro's are no slower and no faster than MH, but they use a shit load less power, are less aggressive on young plants, and kick out zero heat. For me, that's a no brainer.

For heat in the flower room, in the summer, I'm more than happy not to have to run a jet engine sized extractor, and can keep my grow at a manageable temperature with an 8inch RVK running at 1/5th speed.

Something I've thought about now, is that running into winter I will be able to get by with even less extraction and that brings about the possibility of CO2 enrichment..

For me, even if MH was faster (it isn't) the benefits of using flouros greatly outweigh that fact. I keep all my mothers, cloning and veg to a closet, and heat would be an issue. Also, as I'm not having to veg and flower in the same room, I have a perpetual setup, I'm not concerned with losing time on veg.

Fluorescent have there place I'm not knocking them I'm using 4x T5s atm and I use a 150w, but ime they are nothing like as quick as mh not even in the same ball park, I expect led will be quicker to?
My current crop seeds were soaked on the 1st of August and put into flower on the 26/27th August that can't be done with cfls/T5s by me.
Eta..
As I said I'm not knocking them this lives under T5s specifically because it grows slowly and remains easy to maintain.

Oh.. I just thought.. the argument that you can't get round.. You don't have to turn an LED off, to take a decent photo. .. where is the mic drop emoji?

One of many benefits of LED's are the pics with the lights on especially blurple pics, just ask the regulars who help in the problem section.

I showed the yellow picture on purpose because my natural light pictures will steal the show, and I don't mess with journals.

Yeah but who uses blurple? OK OK, you caught me, I grow with HPS and just switch all my lights out to take pictures because I have shares in Samsung.

I've ran floro's for years , cannot beat them , hid has to be distance away for heat issues an in turn causes stretching , mh just causes heat issues

From my personall experience for veg 6400k 250w Envirolite CFL destroyed ALL other veg lights... 6500k T8s came a close 2nd ...and then a 400w Philips MH running over cloocked on a 4000 Lumatek came in 3rd......although i had to run a cool tube so less par and mental heat and fan noise... I tested other lamps to ...the only other bullb id recommend if going HID is either the Horticlututre or Digi........something or other...dual spec hps mh duo......but personnally to use now..... Either 6500k cfl if less than 4x4 ...or 3500k 54 w cob.... but going bigger than 4x4 id go a mixture of CFL and HID MH....save CMH for flowering.... But for me a personnel grow that was 3x3 ....then reduced to 2x2 .....ans ssoon to be upgraded to a 2x4x5.....its still cobs for me 3500k hits the spot all the way till the last 3 weeks ...then add some 660nm and some 3000k and lose the 3500s.... Bang !! DONE !!
