23) Why is that other plant lighting manufacturers offer different lamps for either veg or flower and Inda-Gro only offers one lamp for the entire crop cycle?

When dealing with phosphor based technologies we do not believe in trying to soak our customers by perpetuating the myth that they must have one lamp for vegetative and a different lamp for flowering to be successful.  Now with HID lamps that two lamp approach would be true as these lamps do emit relatively narrow spectrums that concentrate their energy in known regions of chlorophyll sensitivity for either vegetative or flowering.  But with phosphors we can blend phosphors that emit a broad enough spectrum to accomplish full spectrum growth without putting the gardener through the unnecessary expense and hassle of relamping a big cumbersome induction lamp. 

Other reasons would include:

Internally, induction lamps convert the UVc wavelengths (100-280nm) and the phosphors coating the inside of the lamp photoluminesce the lamps output.  When you ask phosphors to convert that UVc energy into the Red regions (610-630nm) you have lost 60% efficiencies in doing so.  It simply does not make sense to ask any fluorescent based technology to produce a primarily red spectrum when the efficiencies are so low in doing so. 

Normal plant photomorphogenesis occurs under broad spectrum sunlight.  When subjecting plants to entirely different artificial spectrums that we 'believe' to be the plants required spectrums for that particular stage of growth but may not be will cause the plants to stress.  It is during this period that the plant is more likely to hermaphrodite, become diseased of infected.         

Plants exposed to broad spectrums of light through the entire plant cycle will grow to their greatest genetic potential.  Here you can see from these lab reports how when the same plant genetics/conditions have been grown under broad spectrum lighting the cannibinoid and terpene profiles were improved.   As can be seen by an independent lab analysis this is true even of a competing induction lamp mfg who sells one lamp for vegetative and another for flower.  Having to have one induction lamp for veg and another for flower is not only expensive and cumbersome if they have to be changed out, the reality is that the lab results, insofar as the quality finish goes, does not support the fundamental reason for having to use two lamps to get through a crop cycle.           

There is a perception that we as manufacturers should not change the paradigm too much.  Gardeners are used to using two lamps.  Subjecting them to a new technology such as induction and throwing a single lamp veg through flower approach would be too much to accept.  It fly's against the way things have always been done.  Well there is a legitimate reason for the two lamp solution with HID but there is no reason a phosphor based grow lamp needs to take that position.
