why does red spectrum ligh..

[mand]

hello mand, i will switch over tomorrow, going to take your advice. its sad to see them looking so down. are you using 400w mh? for your veg.

Hello Mobay Yes I use a 400 watt MH for the vegitive growth, on a 18/6 cycle The MH provides blue light which is the best for vegitive growth.

The 400 watt HPS I use to induce flowering on the 12/12 cycle. The HPS is best for this job as it provides red light.

You see light produces a full spectrum of colours, but we can't see them .............humans can only see white light


In all my grows this is the way I have used the lights, I did once have a crop fail due to the bulbs being worn out, but they were six years old

This present crop is the only one I have had were I have had to mess around with the lights.......................I don't know what it was but something cauesd the plants to react badly by drooping when under the HPS. However it seems to righted itself now as the plants seem quite happy under the HPS.


One thing the problems have learned me though is that plants will flower under a MH bulb. I once read that flowering under MH will reduce the yeild by 10% to that of a plant/crop flowered under an HPS light ...............how true that statement is, I don't know
