I have a 400W MH that I'm using for vegitative growth. I know that the HPS is better for flowering because of the colour spectrum. I was wondering if it would be worth it, in terms of yeild, to get a HPS conversion bulb for the flowering process? For just 1 or 2 plants I wouldn't bother but I'm trying to grow enough until next year. Does anyone think the yield is that much greater that the extra bulb would be worth the cost? BTW I'm growing White Widow & Power Plant.
go with the hps. the mh will work, but the hps will do the job, it provides that red, you want your budz dense right?
yeah the hps gives u the red in the color spectrum that mh just don't have the hps would be worth it.
