I need advice with HPS/MH lighting
Posted 25 September 2011 - 18:38 PM
as i have counted how much would i spent for heating of my greenhouse during winter, i decided that building of a small version of Sativ`s growroom in our basement would be much cheaper. I was thinking about approx. 2 m2 of growing area, which should be enough for my plants (mostly sundews, helis and utrics). I have everything planned, except lighting.
I am thinking about 250 W HPS light, do you think, that it would be enough? Or would be MH light better? I do not have any personal experience with these types of lighting. And which one to choose? I have seen lights from Sylvania, Osram, Philips, GIB, SuperPlant, PowerPlant... Any good experience with any of them?
Thanks in advance for any advice

MH - I discourage to buy GiB, I had a few, all of them broke in 3 month period. Got free replace - the same happened.
HPS - you can go with Philips.

I made some search according to your advices: truly, almost all HPS have the most light in yellow/red and only a very few in blue. However, Osram HQI-T (which, as i understand it, is a MH) has a very nice spectre (complete from blue to red) and Sylvania grolux seems to be the best - it is dual spec bulb, so the blue part is enhanced.
So it is decided, i am going into Sylvania SHP-TS 250W Grolux, which is easy to buy and seems to be very good for plants.
Thank you once more for your help
