Flors vs HPS Ligts

Quick Question:

Would I be better off with 400 Watts of Flourecent Lights at approx 30,000 Total Lumans or 250 Watt HPS Light at approx 35,000. Will the HPS still outperform the 400 Watts of Flourecent?\

Thanks for the help!

the basic answer to your question is yes the hps will outperform the fluorescents. however, your electric costs are greater with hps and the heat is much more intense. i use a 125w fluoro and it works great --from start to finish. where are you growing? in an attic, did you build a growroom? what kind of funds do you have available? who's paying the elctric bill? again, the basic answer is the hps will outperform the fluoros but there are other things to consider.

Floro: Less Cost, Less heat, Cheaper electric bill.
HPS/MH: Much better growth, bigger yield.

Take your pick.

Fourecents are good for vegging clones/seedlings. Switch to HPS once they stablize to gain maximum results.

You want both.

how can electric cost be bigger with hps,if you have to choose between 250 watt hps and 400 watt fluoro?

Thanks for the thoughs around this conversation, I have a growroom set-up 5' Long, 3' Wide & 4' Tall. Budget for a 250 Watt HPS light is available. So it would be worth my time and money to get the HPS for flowering?

You dont want to flower without the HPS!

HAPPY GROWING :)

question for booch.............................

are u just using a 125w fluro for the whole growth??? if so then how many plants do you grow under it and do you get much bud from the finished plant???do u always keep the plants a couple of inches away from the light even when the plants in flower and do u use any side lights or fans or anything like that??

id like to grow with just a fluro so id appreciate the info

professor:
the fluoro i use is from ezhydro (find them on ebay). it is a dual light (half blue half red). i'm blue until flowering. as soon as i switch to 12/12, i flip the light over for the red spectrum. while my grow may not be as big as others, i get a big enough yield for me. and, my buds are big. i don't use any side lights but i do have mylar walls (i spray cardboard with spray on glue (home depot) and attach the mylar). i do keep the plants within an inch of the lights. this means that i have to keep a pretty close watch on growth (which i do anyway). but even of the plants touch the lights temporarily, the plants won't burn (i try not to let this occur and certainly wouldn't recommend testing to see waht happens).
i guess everyone can argue with me, but i've used the 125w dual fluoro from start to finish for two grows. it is not some tiny little fluorescent you get from the hardware store. here's a link to exactly what i have: http://cgi.ebay.com/ws/eBayISAPI.dll...382548877&rd=1

read the reviews. it works.
