That should help you get started.im new to growing with a 400 watt hps i started out with cfls.so i got a few questions if you guys can answer that would be great,an you guys got some real nice looking plants.
1st how close do you put the lights to your plants?
14 inches without a hood, 4-6 inches with a air cooled hood.
2ndwill i get a bigger harvest useing a 400 hps?
Yes, bigger than CFL's
how much do you guys harvest each plant?
1-4 oz depending on setup, etc.
my temps are 72-77 is that okay?
That's fine
last how many plants can you get under a 400 hps?
I like 3 or 4, that fills up my grow box, but depending on how you are going to grow (SOG, SROG), you can grow more.
Also in Cali we have limitations, so I like to grow larger plants to stay under the limits.
thanks i will post my grow with pictures tomorrow,thanks.

1.) Mine was air cooled and within 8" of the tops. but usually more around 12-20" depending on air circulation if not air cooled. Unless you had over 400w of actual light with your cft's you should have a bigger harvest. With my 400w and 5 plants I harvested 9.75oz. If you look further back, smoove got 13oz off of 2 plants, but hes a pro. As far as how many plants, the light covers roughly 3'x3', so how ever you want to pack them in that space will make the numbers vary. usually between 2-8 plants.

Sure you can keep the door open but you WILL screw it up. Its hard to be home every day at the same exact time twice a day. Plus you will be wasting light by letting it go out the door. Oh what about the light? Wont people wonder why your one window is glowing that strange orange color? Why cant you vent? Its not hard to cut a hole and if your renting, who cares it takes an hour to fix it when your going to move. Do it right or dont do it is mt advice.

Damn son...you don't gotta be a prick. I'm a medical grower, and yes i do rent. But, I also RESPECT my landlord, and am not going to willingly destroy paneling just to vent. I'm at home all day anyway...

Easy pal not a prick at all and I'm a med grower to big fucking deal.
Didn''t know your place was paneling sorry. Its not about having respect for your landlord. Notice I said it takes about an hour to fix it? I wouldn't just fuck up someones place and leave it. I have 3 rental properties and wouldn't want that to happen to me. Its not what I'm suggesting at all. Sorry for trying to help but I will still try. Paneling is easy to remove and not damage. Pull it down. put up a piece of drywall in its place. cut what you need and you can then just put the paneling back when your done.
Prick out.........

Im not here to sound like a prick either, but good ventillation is a key ingredient in growing. Not just to keep temps down but to remove stale air and built up moisture from the plants. It also is the only source for new co2 which is needed for healthy plant growth. I would try to find some way to vent that will keep your plants and landlord happy. You might be able to take the door off of its hinges and make a false door out of panda film and accomodate it for an intake and exhaust vent. Then when your done there, just rehang the door. No damage and minimum effort and cost.

I feel like the majority of you wont believe my claim...
But using just my 400 watt HPS and and a 6 bulb four foot T5 I yielded 10 ounces of buds, 1 ounce of hash buds, and nearly an ounce of cooking trim of of ONE Hawaiian Snow.
In a room with 4 plants- 2 that got runted by the monster landrace sativas that sat next to them (the runts yielded 19 grams and 33) and my Hawaiian Snow yielded the 10 ounces of bone dry (way too crispy as I was out of town when drying) and my Neville's Haze that just got cut and looks like it will shatter the record set my the Snow (Guessing 13 ounces).
So for my 4 plant grow under a 400 watt HPS and 6 bulb 4 foot long T5 I yielded an estimated 25 ounces. I will post the weight of the Neville's when it is done drying.
I should mention that I vegged them for 5 weeks to about 2.5-3 feet tall and flowered the snow for 17-18 weeks and the Neville's for 23 weeks. Absurdly long flowering times I know.... During those long flowering weeks I frequently bitched... But with yields like this I'm not complaining.
I should also add that for the last 4 weeks of the Neville's I added another 400 watt hps and used T8's for side lighting.
Also I did not use Co2, I used nearly the entire Advanced line and some supplementals that I've found and stuck with through the years.
Definitely my personal best... Beating the G a watt measure.
