Maxibright Daylight 315 CMH lamp.
Some background information –
The Digilight Daylight 315W kit comes with Daylight reflector (V3) and Philips 315W Agro lamp. This is undoubtedly the best lamp unit that I have ever used to grow my leeks and onions plants under. I have tried quite a few different systems over the years starting off with just ordinary fluorescent tubes then expanding and fitting Gro Lux tubes. From there I went on to fit the SON T Aggro 400 Watt units which I still use today as overall lighting in my large glasshouse. From there I eventually fitted some T5 units which are good but nowhere near as good as this Philips 315W CMH lamps that was designed specifically for plant growth.
Here are some key features –
Prevents stretching and encourages much higher quality growth.
More natural formation of branch inter-nodes for increased plant mass.
Ideal as both supplementary and standalone lighting.
Highly efficient – puts out 1.9 micromole (µmol) per watt of electricity.
Extremely high PAR Levels (photosynthetic active radiation)
The picture shows the difference between leek plants that were potted up on the same day into 9cm pots, those under the Maxibright Daylight 315 CMH lamp were far superior to those that were kept under my SON T Aggro 400 watt lights. Better colour on the flags and a much increased root mass by well over 100%
