Personally I like to balance the spectrum slightly by using some 6400 light BUT in your case I'd go with the 2700's for flowering. Impossible to say re final weight, too many variables.Lets say i chose to use 50/50 on the spectrums(100w 2700k and 100w 6500k) for blooming, would there be a noticeable change in bud-weight compared to 100% 2700k bulbs(i.e 200w 2700k)?
And if so, how much weight would it be?
You might be surprised to see just how much that 30watts of 'blue' light in my little cabinet changes the overall 'tone', theres a noticable slight blue tint in the reflected light quality.Well, you only got 30w of 6400k and thats nothing when you have 300w of 2700k.
In my case its 50/50, so if it really makes a huge difference ill go and get myself another highwatt cfl with warmwhite spectrum.
But numbers are the tasty part, assuming i get 50g of dried buds with my current dual spectrum setup, how much would i get if i go 2700k of the same wattage, assuming everything goes well....theoretically?
