an envirolite 200w is cheap enuff for the whole grow
do a search in google for envirolite and see about purchasing one from there
they come in 2 sizes and 125w and 200w
and in 2 spectrums too
the blue spectrum is for flowering and the red spectrum is for flowering but if ya are going to transplant them outside just go with the blue spectrum bulb they come self ballasted so all ya need is an e40 light fitting
