Spex the box came with 4 bulbs it said 1600 lumens each thats 6400 lumens plus 2 eight watt side lights. Do i need more? Or is it ok?
I did use reflective tape on all the edges to stick the windshield reflectors. So i need 2700k lumens of warm light? Is this to have a mixed spectrum?
they look like 23 watters to me and you telling me that they're 1600 ea im pretty sure they don't make a 25 1/2 watt cfl so whoever you bought the box from probably just rounded up in reality your getting much less with distance at more then 2" away you loose so much with those little 23 watt bulbs plus after a week or so they start to loose their effectivness thats with any light bulb especially fluros especially clfs
6400 lumens isnt really ideal you would want 8k + what i would do is like i said before i would get two more 6500k bulbs maybe 46 or 35w you can put the same ones in there if you want but thats what i would do and add two of those 2700k bulbs to add a little yellow light
the idea with mix spectrum is blue light(6500k) allows for foliage growth while red or yellow(2700k) gives you vertical lanky growth without one or the other you could have a short bushy plant or a tall lanky with no branches both together you get a well balanced plant growth
