yea well I'm ordering a 150w HPS soon, and will be vegging in this area, then flowering in a more spacious place. Air flow seems to be good, as there is an open spot in the floor twards the rear.
you should water the seedling every 2 days they like they soil moist\, as it sprouts roots you should water less, like every 3 to 4 days, and you should move the light closer till you get the new one
when you say water your seedling, do you mean pour in a decent amount to soak in all of the soil? I have been just getting faucet water, and dribbing droplets from my hand onto the surface getting the top layer moist. I fear of over watering the lil guy.
Using a stupid mechanic's flourescent light now, but thinking about ordering a 150HPS setup soon, think that will do for growing one plant? Another question, how often should i be watering this seedling, and how much water each time.
Dude, spend some time reading the GrowFAQ. It covers all of the fundamentals and will answer pretty much any newbie question that you can think of. You'll be much better off spending some time reading that than by posting a thread and waiting for responses.
