Using HPS for vegetation as well as flowering.

Discussion in 'Growing Marijuana Indoors' started by Renzo, Jan 26, 2009.

  1. I'm planning to spend the money on a 600 or 1000 w HPS light so I won't have much left over. Will my freshly germinated seeds reach harvest with an HPS light alone? If not, what is a cheap alternative for the vegging phase?
  2. That HPS will work for vegging. Or, you could get a MH conversion bulb of the same wattage (make sure it is "conversion", which means it will work OK off a HPS ballast). Or you could do CFLs/fluoros for veg. Or a combo of either the HPS or MH conversion with the CFLs/fluoros.
  3. Yea what he said :) Plenty of people use HPS from start to finish. In adding to the comment above, depending on your ballast you may not even need a MH conversion bulb. Looks like all the new digital ballast run MH,HPS, and MH conversion. A 1000w is a bit of an overkill for seedlings but as long as you are not baking them it will do the job, nicely I should add.
