I've been growing with HPS lamps for 10 years but have recently been trying to follow developments in LED technology as this is likely the future of growing.
I am designing a system with a 4 x 8 flowering space. I was considering using 2 1000w HPS air-cooled lamps. I have read about how LED light seems to increase the resin production and density of buds. I don't want to go totally LED because of cost and because I need the heat from the lamps in the summer. I could add some supplementary LED fixtures for improving my crop and filling out the cool spots. I have a ton of questions.
1) Is it true that an HPS light can be replaced with a lower wattage (real watts) LED light?
2) Is there any scientific research into the best light angle for LEDs and growing?
3) I know the spectrum debate will most likely never end but is PAR king? Is there evidence that light outside of the PAR spectrum has some effect on plants? Do you need a fixture w/ x number of light bands to be effective.
So if anyone has any ideas on how to couple HPS and LED lights for flowering I would love to hear it. I'm willing to go with 2 or 3 600w HPS instead of 2 1000w if that helps add some LED while maximizing the foot print.
