You are better off with CFL.
this is a double post.
Well, i think so, yes.
Theres been alot of converations recently about LPS, and after looking at a lumen chart, it seems to have the highest lumen out put, higher than HPS.
Although im not sure, i have never used it, or seen them.
If its not too expensive then try it, otherwise go with CFL's as Zandor said, or save up and get a HPS
What is "too expensive" to you? Because if it's higher than $300 then I think I might have a site that has a HPS light for only $249.00. I dont think the lights are expensive, they are well worth it.Quote:

EBAY is the answer to cheap growing equipment. Some people get paranoid about eBay selling your info to the police, but I really dont think eBay are gonna sell info to the cops about someone buying a couple of lights. Im sure that if you ordered ten 1000w HPS lights and a few hydro growing kits they might be interested though.
Try and find a person that lives locally thats selling stuff. I found someone selling a 250w HPS, ballast, reflector (decent 'enclosed' one, not them useless Dutch Barn jobbies where light gets reflected out to the sides aswell), timer and relay for £90, so I snapped it up. Probably couldve found it cheaper, but when I went to collect it (did the deal outside of eBay) we ended up having a toke and now Ive got a new friend.
Thanks for the information guys,and orangeman,I checked out that site,pretty groovy.I might order one of those 400 watt hps.They are pretty cheap.I'm using flouresents right now,And I'm not to pleased.I wanna start flowering her,but I need some better lighting.Are Metal Halide good to use for flowering?Any info is greatly appreciated.PEACE
be wary , ... a lot of those lamps I've seen on eBay are 'converted' Used lights, they MAY have thousands of hours on their ballasts, etc ... not to say you can't find a bargain, just be aware ... :smokin:
Lip does not the LPS lights have a shift in the color spectrum outside of what we use? It may have lumens but unless things have changed (and they do) the last time I checked they were above 8200k and we use 2700k-6500k
I could be wrong; I have not looked into the new bulbs. I just quoted my past experience from memmory
If you're british, try basement lighting, I got a decent 400w HPS for about 70 quid.
Not sure, i was under the impression that it was high lumen, right spectrums.Quote:

Ok fellows,I just found some invaluable info on this low pressure deal.I was looking through a website,and somebody asked this very question,and the answer is no,you can't grow cannabis with low pressure sodium.Low pressure sodium lights put out light that is unusable by plants.It also says that your plants can die if you use only low pressure on them,oh well I guess I have to fork out the big bucks for a high pressure.Oh yeah,and anbody ever tried to use metal hallide for flowering instead of hps?I would love to know what the diff is.PEACE
Thankyou FireBrand77.
Now we know.
MH lights are the other end of the spectrum of the lps lights. They still do not have the proper color spectrum. They are at the other end and will produce more heat then you want as well.
Sorry but we only use a small spectrum of light 2700k and 6500k are the usable spectrum the plants will grow best under.
That means CFL that is the low end but it's best to use HID lights.

that may help ... :smokin:
Yep sure did thanxxx,now i know for sure.PEACE
Nope, most people use MH for vegitative and HPS for flowering, good think about the Optilux is it allows HPS and MH in the same system so you dont have to buy two different light systems.Quote:
