Any advice for my first grow?

I'm currently planning for my first grow in the next week or so. I ordered an 400 watt dimmable grow tent set. My tent is 60x60x78. Is this tent too big for a 400 watt light? I am planning to grow six auto plants. I got a northern light variety. Is 6 plants too much for my 400 watt light? Could I do more than six? I have read that these plants tend to be smaller and do not require very strong light to thrive. I am gonna do a 16 an 8 light cycle. Any feedback would be appreciated.

that is a large space for a 400 watt, just keep them in the back 2' x 4' area (or 3' x 3'). You can easily grow 12 autos under the 400 watt. I would go for a longer period of light, 18/6 at least.

I figured the tent was too big. I was thinking that if things went good I might get a 600 watt light later on down the road, or put led panels on the walls inside. If I grew 12 with the 400 watt light would that sacrifice yield? How far away should the light be when you first plant the seed? Is there any common beginner mistakes to watch out for?

with auto flowering plants your not talking about growing 'trees' or bushes, time is limited so you want the appropriate size vessel to support the plant, 2-5 gallon will easily support the quick growing autos and I'm sure you can fit a dozen of them under a 400W footprint. If they overgrow the space then I'll be a monkey's uncle. So there.

How many plants could I fit in my grow tent total

Thomas, This isn't your thread to ask questions. I believe this is J_Julz thread for him to ask questions. Do you have an answer to his question?

I didn't know we couldn't ask questions if it wasn't the person who started the post sorry an no I don't have any answers for him at the time for his questions at hand check back wit me at a later date an I jus might be able to answer his questions

So when I start these out do I need the full 400 watts or can I bring up the watts as the plants grow?

It's amazing how many people have viewed this thread an nobody can offer any advice.
