As a general rule the odor from the vegging plants isn't as strong as from flowering ones, and a lot of what determines odor is strain dependent. Still, if you need stealth...

You are going to need to vent your grow-op - suck in fresh air, blow out old air - so it's very easy to incorporate a carbon/kitty litter filter into your exhaust system. There's a sticky with real good directions for building a DIY filter somewhere here in the Grow section. I've made a couple filters from those instructions. It's pretty simple and inexpensive to do.

Here's a link for filter: http://boards.cannabis.com/grow-faqs/99371-diy-how-carbon-filter.html

Good luck!:thumbsup:
