Full spectrum lighting stand upgrade

Sitting in my plant room with a cup of coffee I realised the new acquisitions (cuttings and air layered plants) would need additional lighting through the dark winter months, but due to the lack of space this was going to be a problem. Looking at the present setup (illustrated below) there is an unused area (Orange circle) that could be utilised if a shelf or rack could be fitted and still allow the light to filter down to the pants below.

This full spectrum lighting set up is adjustable and can be raised or lowered depending on the requirement. Tubes ‘A’ slide up and down inside tubes ‘B’ and are locked into place by the twist clamps ‘C’ in addition, the light fixture can also be raised or lowered as it hangs on adjustable chains.

Most kitchen units above the sink where the crockery is kept has wire racks but, rather than vandalised mine, the search began for one that would suit my needs. Many were of the wrong size and shape and rather expensive nonetheless, perseverance paid off as one suiting my dimensions was found for very little money. (7€)

Rack

The problem is to find a way of fitting a rack without drilling holes in tubes ‘A’ and ‘B’ because, this would destroy their telescopic sliding ability. The first thought was to use pipe clamps but this was rejected because, they are basically loose fitting and over tightening could damage the outer tubes ‘B’. The solution came from a boat suppliers who had hard plastic oarlocks of various sizes with pre-drilled fixing holes (red arrows) including 2.5cm inside diameter which were a good tight fit as the ‘B’ tubes were of the same dimensions.

 

Oarlocks

After the rack had been cut to size scrap aluminium angle left over from a previous project was cut to fit each corner, each was drilled and riveted including a small hole at the top of the upright to take the chain. A piece of flat aluminium bar was then bolted to the angle upright then a further 2 holes were drilled to take the oarlocks as shown below.

Rack fixings

The rack was then fitted to the lighting stand and on its own was able to take weight due to the snug fit, but rather be safe than sorry 4 adjustable chains one at each corner of the rack and looped over the main cross bar for added strength.

Rack and stand

It can be argued that this full spectrum lighting setup (90cm x 45cm) with a footprint of over a metre is quite small and such a perception would be correct, but in a restricted area one has to utilize the space to the best advantage. Another obvious problem is that by placing plants on the shelf the path of light is restricted, the solution is to arrange the plants so all receive equal share of light.

A full spectrum lighting stand can be made from wood, metal or hard plastic (ABS – Acrylonitrile butadiene styrene) or adapted from a coat stand as this one was, it just takes a bit of working out the intended space and footprint. If someone has already constructed their own lighting stand, I would be glad to hear your comments. Until next time, BW, N.
