How large is the jade in question? Could we see the photo pls?

I could post one later, Rina. The plant is between 18" and 24" tall. The trunk is about the diameter of a coffee mug. It's in a 10" pot, I believe.

What are you inclined to recommend for lighting types?

Is it okay to mix fluorescent and LED bulbs?

In any case, I imagine that I would keep the fluorescent light overhead and position the LED (or fluorescent if that's the better option) lights on clamps fixtures on either side of the rack such that the light was pointed at a 45 degree angle toward the lower branches.

I've seen 4 packs of fluorescent, 6500K light bulbs at Home Depot. I think the price was around $13.00 for the 4 pack.

If you wanted to use clamps to make sure the lower branches, you could use that

Thanks for the suggestions.

Is there any benefit to switching over to LEDs, aside from obvious energy savings? One benefit that I see is that the plant/bulb spacing for LEDs is around 1 to 2 feet to allow the light to properly mix before hitting the plants. This would mean that the LED bulbs would not only take care of the lower branches on the large jade, but would also hit the smaller jades that I have under the grow light, which are currently pretty far from the overhead light (a couple feet) because the fixture is positioned relative to the large jade. I guess I'm trying to determine whether I can justify the extra $30 in costs if I go with LED bulbs ($22/bulb) versus the fluorescent bulbs that Manuel suggested ($10/4-pack).

How high you keep light above should depend on heat of that light source. If you keep incadescent bulb close to the plant, it could burn even if it is small wattage.

LED and fluoro and CFL bulbs emit much less heat (some differences are there too), and while more expensive to purchase, they are longer lasting and use less energy. So if you use lights for extensive length of time/hours a day, these definitely make sense.

If you have shorter plants, it may be easier to rise them on some kind of shelving or stands (whatever is possible in your situation) to bring them to level of the highest plant. If you have many plants, it would be easy to keep all of the shorter ones under one light set up while taller ones are under another set up. Obviously, not knowing your general set up, these are just ideas.

I have plants arranged according to height. Some that don't fit anywhere are propped up on upturned pot , or even piece of tubing - works very well. But you may be concerned about aesthetics of it - in my case, it doesn't matter...they are not in LR or any 'public display' area. I have some grey color couplings, 3" dia that work extremely well as supports. They don't look bad at all :) being same color, and are stable.

From what I've read, LED is on a big growth curve in grow lights. I'm happy with fluorescents at 6400/6500K at this point.
