umm i think the war was over along time ago. HPS are better for flower, however cfl vs mh is debatable in veg mode. More power from MH, CFl can be put very close to the plant, very litte heat from cfl
lol... havent you heard of a cooltube? hell or any other closed reflector?Lumens per watt isn't really a good measurement of how good a light is for growing. In the case of HPS lights, the lights have to be further away from the plants than CFLs do, so more light is lost before it can even reach the plant. CFLs can be placed closer to the leaf canopy resulting in less light being lost.
Lumens aren't even an accurate way to measure how much usable light the plants are getting, because lumens are for humans (lumens are how much light we can SEE, not how much light the plants can use), so saying that HPS beats out CFL because it puts out more lumens per watt is ridiculous.
funny quoteI just think this shit is hilarious. How bout we all take pics of our dicks and compare sizes as well. I grow bud that gets me real high with a few cheap cfls and thats good enough for me.
There's plenty of cfl grow journals so if ya wanna compare then go have a look.
For some reason HPS people seem to think we all want huge grows and we aren't doing it right. Not the case at all
I can't stand CFL's. I was biting my tongue, but they are worthless and annoying. They do the same job, produce the same heat and are just much harder to manage. I just want to put a light at the top of my grow room and cover the space properly. I don't want to play the magical, million chords march and do the whole CFL song and & dance moving lights around all the time to keep them within 2" of the plants.
Why would I want 40 individual lights that will yeild less more than likely and POSSIBLY the same, but certainly not more than my HPS lights?
It doesn't lower the electricity bill as well as people think. I can get more out of a 250w HPS than I can with 250w of CFL's and 250w it's 250w no matter how you slice it.
But I don't hate on others that choose to play the song and dance, to each their own. If you enjoy it and grows you dank sticky than by all means. I ride a sportbike and not a Harly, but I still love everyone on two wheels. I love anyone who grows, soil, hydro, CFL, HPS, LED, DWC, EBB&FLOW, who cares?
once you get a mh/ hps light you will never go back. 1 is better than 64 and plus you dont have to worry about "losing light because of distance away". c'mon its a space ray! cfls are never better-only cheaper start up cost for a beginner but not even true because mh/hps are more efficient anyway. doing it right first is cheaper and better than trying to rig some elaborate, inferior shit and then buying the real shit later trust me thats what i didHow is this,
CFL for veg, switch to 600 watt hps for flower. got my cfl set up first, so I don't want to change until flower. Also I only have HPS red bulb, and don't want to spring for another bulb for veg on my first grow.
