Double stacked vertical bare bulb holder?

[Miraculous Meds]

I do it the same with a bulb set with the mogul flush at the bottom and one at the top. The only time I do move it is when I want the plants to stretch up . Then I place the top bulb higher than the top of the plant. Not much but tip of the bulb at or just above the plants.

Tips from the master. Thanks,IC

a very small diameter cable with crimps would be less intrusive than chain, attached to a length of link chain above for adjusting height. fishing leader works well.
