Wat do you mean by blue light and red light, I kno that its like blue light spectrum for vegging and red for flowering (something like that) but like can i see a picture of what these lights look like? are they CFL's???
And did you mean he used the 2 40 watts and a blue/red depending on what period of growing he was in?
Would anyone be able to answer this or show me a picture of red/blue light bulbs?
check it out
cct 5000 - 8000 color deep blue Effect encourages excellent leaf and stem growth---- cct 4000 - 5000 color light blue effect encourages good leaf and stem growth----- cct 4000 color nuetral white effect promotes normal growth-------- cct 3700 - 4000 color warm neutral effect promotes rapid growth -------cct 3000 - 3700 color warmer yellow neutral effect highly active photosynthesis for all stages of growth------------ cct 1500 -3000 color hot orange or red effect promotes flowering
cct stands for correlated color temperature and is mesured in kelvin (K)
Triiiipppeh, so actually usuing a coloured bulb will help in different ways of your plants growth or does it all depends on how many "kelvins" are being put out?
edit: WooHoo :D page 2
you need to emit a certain light wave not just paint a bulb red, most bulbs that will be red or blue are that color for a reason though check the cct's
Alright thanks alot man, I appreciate the detailed answeres :) Ill post up some new pics of my grow box's progress soon.
Peace
Damn, I found two bulbs in my basement a red and a blue one. But there is no box so I cant tell what cct they are :( is there any other way to find out?
look for any code or text on the bulb and search for it or you can bring it in to a hydroponics store or even hardware store and see if you can find a match.
