l.e.d growlights ?

with leds is the turnaround slower than hps and are led lights good.some info would be great

There is a lot to be learnt still about growing with led lights. The problem is that your plants need a mixture of red and blue spectrum's in the light for maximum yield but with the LED lights on the market now days they just don't seem to put out the same lumens as your HID HPS or metal halide do. I would truthfully suggest buying enhanced spectrum HPS bulbs like the ones from phillips or Hortilux. They are more expensive but I have quite a bit of experience with them and trust me it is worth the extra buck.

cheers

not really they are recomended for experence growers, they dont have powerful light

I cant say from experience as I have not tried them personally, but from research I have done into them it seems it would be best to avoid them. The only good press I have found is from the people selling them. General growers that I kow that have used them pretty much sell them as soon as they get them and go back to HPS.

yes we are giving our moneys to china for some crappy shiny things.

I am using a light from htg and they are the most beautiful plants i have seen. A deep lush green, short and no stretch at all. they actually bend towards the light. I am in my first week of flower and i do know i will trim off the bottom fan and a few branches to sort of lollipop them. Get a good one they are expensive. don't do the ebay they have a lot of fake ones on there. good luck

thanks for the info im lookin at one called a ufo witch is stated to have the = lumins as 400w hps witch im currintly using it will cost $990 nz dollars.
so im now undicided what to do???

bro ... did you ever make the decision to do LED??? From my experience the ones that work well are also with HID HUT. they were at the recent hydro show out west. great products!!!

This is a test I am doing

I was also intrigued by articles I have read in Maximum Yield Magazine about LED's. Low power output high wattage and they say it puts off no heat. Anyone ever used LED's?!?!

This is specs on mine I have the 120w

My advice thus far? Don't do it. Get an HPS and you WILL be happier. LED's will come around, but not just yet.

cfl's are better then leds

Bought the UFO Veg it did ok, but i would never recommend this light during flowering unless you want very small buds, it just cant compete with the HPS, although you'll need to vent it due to heat, its well worth the prize

I was just reading an article that about LED growing and how Lumens aren't even relevant for LEDs. Lumens are a calculation of light that our can see. What you should be concerned with LED's is the wavelengths of light that it provides your plants. That's actually equally as important as lumens. I was reading future LED's won't have a high lumen counts at all. Rather they'll concentrate on specific wave lengths of light to maximize your grow. HID's while the best of the best (for now) waste a lot of energy on wavelengths of light that plants really don't need. So eventually watt for watt LED's will trump HID's when that will happen who knows? For now HID's are king!
