aye mates, very new to this forum. TO get right to the point, hope everyone is doing well, and has anyone tried LED lights? Any of them. THey say blue for veg and REd for bloom. I was curious as to how effective they are, and they seem very handy for stealth blooms.*which is the application intended**
thank you all, and hope to hear your thoughts!

Non of you veteran growers have ever tried LED lighting to grow their plants? they say the plant absorbs 95% of the light emited from one and compare it to a 500w HID but it only pulls 10 watts. I would really like having some knowledable input please. THis is my first grow, but ive been lurking around this board for about 4 days LOL. heres a link to a type of led im looking at. eBay: LED Grow Light RED 168 growing lights Orchid Tropical (item 290069267959 end time Jan-16-07 12:42:11 PST)

I saw this too, while surfing around on eBay. I thought it was rather funny. If you're going to try them, I'm sure there are people who would want to hear about it. I just can't see it, though...

heres a link with some research done. THey used more LED bulbs than HID did for their setup. But if you scroll down to the end of the page it has the results listed. not too shabby. IT says that the LED outperformed growth in certain stages, but over all results were equal. WHich is very exciting because you use less power, and no heat is generated meaning less ventation is required. Im preparing to order some Leds, be about a month or so before i can give feedback on it

leds deffo interest me .ive seen a grow done with them on another forum but he only used them through vegging ,and i have to say i was impressed .the only thing im not impressed by is the price of a decent led set up ( the cheap ones just dont do the job ) .im waiting for the price to come down and more research to be done ,but in my opinion leds are definately the future of growing .

What system would you say is good for one herb crop, in a box with aluminium foil inside.

LEDs are excellent for plants and all living organisms -- best is white for plants. Have experimented with warm and cool whites and got same results. All plants thrive under LEDs. You can make them yourself. To see a light that would be appropriate for growing plants, go to XXXXXXX and select prototype. My jade plant has never bloomed in 30 years, but did so under this light.

Aluminum Foil:
Aluminum foil is no more than 55% reflective - if used, make sure that the dull side is the one that is used to reflect the light. When it becomes creased its reflectivity is even lower (around 35%.) It is also very dangerous to use because it creates hotspots easily, is electrically conductive, and is a fire hazard when it is in close contact with HID lighting. Attaching this to walls is a pain and usually using aluminum tape or glue is the best way. This should only be used as a last resort, and even then its usefulness is questionable.

paint the box matt white instead of the foil its much better

HOw much did that system cost you? and did they veg and bud all under that one light?

Thanks for all your replies!! I am taking notes
