Thoughts on New Wave systems and more...
I'd like to provide my hoyas with an area to grow this coming cold season. Yes, I'm planing ahead slightly :)
I'd like to use one of those metal racks that can be purchased through the hardware stores. Usually they are available with between 2 and 4 tiers and have adjustable height shelves.
The one I own has shelves which are roughly 36"x18".
I'm considering the purchase of T5 HO fluorescent systems to hang from the underside of the shelves above. I'm familiar with Sunlight Supply and their aquarium hobby lights, but how do their horticultural lights hold up? The 'New Wave' systems look relatively affordable and like they may serve my purpose.
Also, with 36" long shelves, could I get away with centering 24" fixtures or would it be necessary to purchase the 48" units? What kind of light broadcast do the reflectors give? The 2 bulb systems are only 6" wide, will those be enough to cover the 18" shelf depth?
I'm primarily interested in new plant growth, not flowering. I believe the 6500K bulbs are usually sold for that purpose. What I'm not sure of is the nm. rating for those bulbs. My understanding is that somewhere in the 400nm-520nm area is required for vegetative growth. I haven't seen these specs mentioned for a lot of bulbs, they typically only refer to their Kelvin rating.
Any input here to help out the new guy on the block would be appreciated.
Thanks in advance for your help.
