Could someone please tell me if the sockets we screw our HPS bulbs into are the same as the ones in the US? And also if I would be able to wire an ozzie lead (from an existing reflector I have) to one of these sockets? Cheers.

just out of curriosity what type of globes are people using, at the moment im using a 400w son t agro (made by phillips) globe, last globe i used a luchergrow (if spelled right) also used a sun master. the son t is less harsh in light colour and with the panda plastic it gets a pinkish sort of a tone to it. the other 2 where more or less a yellow sort of a light, at the moment like the son t more but what are other people using and what are your thoughts on globes.

any one here had any thing to do with growing under LEDS, there are a few posts about it in the overgrow froums, and by all accounts they are better than a 1000w hps. they have a varibale coulor spectrm going from blue through to red so you can wind it around through veg to bud. they cost about 2-3 grand to set up (to buy one) but i am thinking of getting a mate to build me one, if any one has any info it would be appricated. the other one that insterests me is that for medical purposes they have made LEDS that emmit pure white light. where on the spectrum is this and what would happen to a plant under white light.

I'm running a 600W HPS in a wardrobe. I've managed to get heat down to an acceptable level but I still appear to be bleaching the upper leaves of my plants that are directly under the globe. :scratchin I've seen some of those Super Spreaders advertised around(like a V shaped metal guard with holes in it) and am wondering if that is the answer to my problems? Anyone used these or have any experience with them?

went to Bunnings today and saw those 48Watt bulbs that Wilderbud has been talking about. They come in a box. They were Nelson Electrics from memory. But at twenty something dollars each I though the 28watt ones for $11 were better value. Once you start paying over $20 plus the added cost of the socket for each compact fluoro you may as well get a small HID IMO. Anyway saw several neat looking wall vent extraction fan units and inline fan units with ducting and louvred vents on each end. There were HPM ones and another brand. The inline fans looked like the centrifugal ones they have in the hydro shops but I couldn't be sure. Anyway they looked nice and perfect to…

hey people I was just reading a hydro book from the eighties, and it has a bit about lps and how they produce light only in a narrow portion of the spectrum (yellow/orange) I was curious as to whether this type of light would be suitable for use with a 400 hps son agro, for the flowering? :scratchin
