Hi there Parcero, first of many congrats on your first grow! The fact you got to this stage on your first go always deserves mad props! Alot of people fail on there first grow because they don't research enough in the first place and when they run in to problems, by the time they find the answer it's too late. Read through the whole thread and you couldn't of done much else IMHO. I think you've done a brilliant job and I can't help but chuckle to myself with the lighting you've got set up
My advice (im no expert mind) would be to have less lighting of better quality, in this I mean rather than having 3x 400w hps, i'd go for 2 600w's (although as you already have the 400's it would be costly to replace them). I only say this because the 600'w will penetrate further down and im sure I read somewhere that you get more lumens per watt with the 600's than you do with the 400's. I think your having the same issue I had with my first couple of grows, I was growing 3-4 plants with a 400w in 10L pots and they grew to be around 4ft tall and whilst it looked great the only real dense buds were at the top/main colas, all the rest, like you say were as light as a feather, especially when dried out. So for my next grow I intend on keeping them shorter, i'd rather have a short, 90% dense buds plant than a tall 50% dense/50% airy bud plant. Hope that makes some sense? Like i said im no expert though, i've just started a grow and even though im using 600's I still hope to have a finishing height of 3ft.
Great job again though, enjoy the fruits of your labour! :aok:
p.s forget to add, getting dense buds isn't just about the light but I know it goes a fair way to helping. The best dense bud plants i've seen generally are from plants grown with air cooled hoods, this enables the light to be sometimes 6-8" away from the top of the canopy without burning 'em. A 600w air cooled light 8" away is far batter than a 1000w non air cooled light as it would have to be around 2ft away from the plants to stop heat burn. In turn this means the light intesitiy is lost the further the bulb is away from the plants. Sorry if you already knew this, just thought i'd try to explain where the bud light'ness is coming from. Everything else your doing seems to be just fine.
