I'm thinking it may be less stressful on the plants for the first few days while transitioning from CFL to a 600 watt HPS.I don't understand why some people do this . If you buy a say 600W light , why not rum it at full power ? Why would someone buy a certain light and run it weaker than you can ? My light is a 600W dimmable but I have never turned it down .
U can reduce stress by raising the lights.
Dimming doesn't cause significant damage to the equipment.
It doesn't significantly effect spectrum.
i agree,i step it up by the weekI'm thinking it may be less stressful on the plants for the first few days while transitioning from CFL to a 600 watt HPS.
thanks Greenhouse.....that's what I thought, just another RIU mythYea the point of a dimmable ballast is clear and simple imo I have a few dimmable ballast that all have a job 50% when the young ones first see the light at a lower hight then 75% after a short while then up to 100% when they r in full flow and finally 110% when your plant's are near the end.I have 8plants that r near finishing and have boosted the ballasts to maximum 660 watts and can clearly see a difference in my plants with the extra power being applied so isint it simple enuff if you have it use it to full effect otherwise just buy a cheaper standard ballast........and no I have never heard of a ballast that diminishes in use when running on a lower setting same applies with the bulb.....
