Here's an update just four days on. Over the weekend I installed the inline heater, ran the filter pipes and moved the T5HO ballast to below the cabinet. Excuse the mess, it's mostly CO2 stuff, and the tripod I'm doing a time lapse photo series with. Also, I'm surprised that in just four days I'm getting so much new growth from the Glosso, by this time next week I should be topping it.
New glosso leaves, the original leaves should die off.
The new cupboard internals.
6 way surge protected multiboard with light timers, T5HO ballast behind.
Filter pipes held on with pipe clips I painted black, inline heater somewhat hidden by the tripod.
