Colours are the nurturelite® colours, these are detailed more on charts for SPDs

Aquatic Plants: Actinic Blue for Marine Plants and PURple for Tropical & Freshwater plants.

Land Plants: Warning: All fluorescent lights emit UV light, PURple emmits proportionally the most. When using any fluorescent lighting with early seedlings or early cuttings they would be best be protected from copious amounts of UV. This is easily remedied with a single sheet of glass or perspex or plastic, between the fluorescent light source and the plant tops, a Propagator top is ideal. (see PS1)

In many circumstances a combination of only White and Red are traditionally used, White for all pre-flower stages and red for all post flower stages.

A favourite for all pre-flower stages is 50% PURple and 50% Gold, a favourite for all post flower stages is 30% PURple and 70% Red.

PURple is known to be favoured for growing equitorial plants, such as Orchids and is proven to promote the production of flavoids which can enhance the colour, odour and and flavour of plants.
