when comparing say 8 bulb 52watt t5 ho to say a 600w mh, what would be the comparisons? Such as lumens, par, and difference in cost of electricity?
I notice that mh bulbs seem to be not as bright as say their hps counterpart. Does that mean that they are actually using less power than 600w? it all can get a little confusing.
And while browsing i keep reading about this cmh 315w lights. are you familiar with them. They advertise 600w output for 350w of true power draw. That seems really nice. Is it bullshit, or a good light. Just trying to understand lights, par, lumens, and electricity costs.
I also notice you know a lot about led lights. And you plan to use one, or already do.. I never notice you trying to push those light on me. any reason why? Are you not happy with your light at the moment, or just figure that the expense of a good led is just something i need to worry about down the road?
Either way, you know me,,, I always have questions, and am always trying to learn more... drying rack showed up, and I found a dark cool place in the basement for it. rh a little high between 70 and 75% but temps are about 77.
Best I can do. gonna pick up a circulating fan today to keep air moving around in the room. hopefully that will help with the rh.
hope your having a good day :) Sry to hit you with questions already. Off work today and just working around the house. No hurry on the questions. I just posted some questions that i been meaning to ask you.
so.....600 vs T-5
T-5 415 watts shallow penetration
600 = 600 deeper penetration
as for CMH.....they are awesome lights....
in my experience....all the hype on this is BS
a 650 cmh is comparible to 600mh
a 350 cmh = 400w mh
companys all try to compare apples to oranges
the 350 cmh has a better spectrum and is mich more efficient than the mh
but 350w = 350w
now you can het super technical and say
350cmh is say 45% efficient
= 157w of light to the canopy...the rest = heat
the 600mh may only be 30% efficient
= 180w to the canopy the rest heat
but those 30 watts makes a difference
cost wise maybe not
but really when you cost out the electrical expense
350w really is only a fraction of a cent cheaper than 600w
hope tha answers that
as for my led
I dont think I would trade it for the world
I would however beef it up with an hps
just to pound the canopy
I dont push the LED that I have on anyone new because it is a heafty cost for a really genuine LED fixture and much more affordable to grab a HPS batwing and Ballast
hell 350-400$ gets you and entire setup
or if tou have hogh enough cealings...a
gavita
my 310w led puts 155w to the canopy as it is 50% efficient
actually it is better than that because the heat that it puts out the plants can absorb and use ....as opposed to the heat that HID exutes
as for drying.....should be fine with enough air movement
it will just dry reall slow.....which is actually a really good thing.....also....the colder it gets the dryer it gets correct
hope that answers some of your questions
