HPS or LED

Discussion in 'Lighting' started by Porky 1982, May 30, 2019.

  1. Ok ive decided to go indoors or my wife has decided to let me grow indoors much to my surprise. Now i know absolutely fuck all about lightning as ive only ever grown outside. Im going to buy a 1.2 x 2.4 tent. Question is what lighting should i use. Im not really bias either way. I like HPS for the colder months but i like LED for the warmer months.
    Ive been doin some reading about life span of each light and some say there LEDs last for up 50k hours now that sounds like total bullshit to me but i really dont know as others say like shitty mars that their lights loose 5% a year in efficiency not that i would buy one. Ive also read some HPS only have a life span of 1000 hours.
    Also what brands are good and which ones should i avoid. All suggestions are welcome. I am in Australia so some things you may mention might not be available to me. Thanks all.

  3. Cmh best of both worlds
     
  4. Ive read that you should not enter a grow space while CMH is on as they can cause skin cancer. Thays the only reason i was steering clear of them.

  5. Idk im still okay lol, how may hours a day do you plan on staying under the lights? Most of the time my tents only open for 5-10 minutes at a time. Im more scared of the sun, good thing your wife said you can grow inside. Cancer is bad mmkayy.
     
  6. You'll have to use LED if it is that small of grow tent. Check out quantum boards. I have no experience with them but very impressive results.

    Yea ive heard similar they do put out uv rays but like i said like i said tho you dont really see it that much, i get way more sunrays than grow light exposure, and here are my side by side results led vs cmh.

  12. Remarkable progress under what many would consider less than ideal here; two 75w COB units that draw about 45w from wall each.

  13. So ended up going with 3 of these. Got them for a bit less than the asking price which is nice as well. Screenshot_20190601-193458_Chrome.jpg
