LOL, Dude! before you even think of setting all this up you should have learnt about it first.
just get this.
A pot plant needs light, a lot of light so why put them far away in the first place,
always put your light as close as possible, ALWAYS. just always make sure that its not to hot for your plant, put a thermometer just above your plant or your hand and its to hot put the light up more.
Plants need around 10.000 Lumens to grow good, always.
2700K is the meaning for a red spectrum light and has NOTHING to do with Lumens.
light say for example a 28W fluorescent bulb 6400k 1200L
6400k would the the spectrum (blue)
and 1200L would be the amount of light giving away. (1200 Lumens)
so for veg state your gonna need at least 5000lumens (5 of the fluorescent)
since the light lumens add up, but the spectrum stays at 6400K
any more questions?
