thats what I ment cloudz. lol
Yea, it causes less stress to my plant if you slowly increase the dark hours. I don't think it's a noticeable level of stress personally though.some Ppl. do go down.. along the way ..
I wonder how much heat it puts out compared to say...200w of CFLs. I have around 13k lumens with that, but if a 100w gives 10k and a comparable amount of heat that works too.100w hps is good for a small grow i would think a 40cmx40cm foot print 3-4" from top of the plant should be good in a shade
i would think you could yeild 1-2oz's from that light
but i would not grow more than 4 plants under that light
I grow using CFLs and will probably move onto growing with LEDs. HIDs give more lumens per watt so they're actually more efficient that CFLs. I imagine heat is a issue, but this one guy, brettsog, is growing in his closet with a 250w and his temps are 30c. Too hot, I know, but knock it down to 150w give it some proper ventilation(that he lacks for his 250w) and you get almost twice the lumen output of 150w in CFLs. All this "they generate too much heat" is probably people thinking about the 400,600 and 1000w HIDs. I'm just curious about finding that sweet spot for a grow of 3-4 plants.wouldnt bother .. realy .. no offend .. but then I much MUCH rather got T5 or CLF about the same penetration and lot less heat I belive ?
and less eletricity use maybe ? no expert .. just like my T5 and if heat is a problem with even a small 100W HPS I wouldnt use a sec. to think about it ..
try it that worse that could happen is needing to put them back inI lied about HPS.looked at the box,its 150w.They did have 100w,75w & i think there was a 60w as well.Phillips.Got it at home depot.I checked out manufacturer for my bulbs.They dont call them biax,phototron does.they're cfl and gelco claims they're long lasting/low heat.If I took,say,2 of six out of the gizmo & maybe spun plants every so often,would it be a help or hinderance?
I checked out Blackstar's website and they said their 90w LED is equal to a 350w HID. Only like $180.i still think hps would give off more heat
but it would be close
if i had a heat problem and have a plant that takes well to topping and lst and have the space
you could bye some t5 tubes top and lst or scrog them
under 2 of these with the red bulb and should increase your yeild and use less electric
and heat

but reducing heat and increasing yeild is hard
led might be a another option
are they the Red 2700k 150w light cfl with shadeI lied about HPS.looked at the box,its 150w.They did have 100w,75w & i think there was a 60w as well.Phillips.Got it at home depot.I checked out manufacturer for my bulbs.They dont call them biax,phototron does.they're cfl and gelco claims they're long lasting/low heat.If I took,say,2 of six out of the gizmo & maybe spun plants every so often,would it be a help or hinderance?
90w ufo are meant to be good for veg and scrogI checked out Blackstar's website and they said their 90w LED is equal to a 350w HID. Only like $180.
all the other posts I've read get a little uppity if your lights are so close.Are you speaking from personal experiance?If so how many times have you deone this>I am not mocking you,Ireally wanna know.Thanxare they the Red 2700k 150w light cfl with shade
in your set up i would spin the plants
the grow area max 2ft x 2ft and spin the plant 1/4 turn a day
and you could pull 1-2 oz's
if you use 4 plants in 2ltrs pot
and try to get 1/2 oz off each plant
i would still top them and pull the sides down and keep the light 3-4" from top of plant
could you put a link on here so i can find plants getting eatenAbout those pics.I got my threads confused.Its "marajuana plant problems",sub forum "bugs", in thread "plants getting eaten.I'm a little burnt out I guess.I can't grow it worth a shit,but I know where to get it.
