add more light?

so i have a 400 watt hps in a grow tent with 5 plants. i also have a 150 watt hps would adding that do much more? here they are as of yesterday. not close ups but you should get the point. only 3 weeks old from showing sex. so im guessing a good at least 6 weeks to go.

There looking real good... Throw the 150 watter in their too, it will help tremendously....

thanks!.. i have grown with cfls once or twice in a closet but this is my 1st time using hps and the grow tent. this grow i just used some bag seeds so i could get used to everything before i use the good beans.

Good idea to get a feel of your growing conditions... That 150 watt shouldn't increase heat to much, that's the only thing to watch for... What are you planning on growing next time around?

i have a fan plus i have a airfliter + fan and ducting set up so that should keep the heat at bay right? plus its fall so temps get 50 and below during days. as far as what to grow next i am not sure. what would you suggest? nothing crazy hard but with a nice yeild for what im running.

Those look great.

Add the light only if you can manage the heat.

Your nug shots look pretty good, but to the trained eye they don't look dense. That's because your temps are high. They're getting good light, so growth is good, but they have trouble establishing density in higher temps. That third shot especially looks on the airy side. You won't be thrilled with the harvest if you just keep increasing light without managing heat.

edit:
But it could just be the way the strain is developing... Since your leaves don't look heat stressed. didn't realize you were only three weeks in. Plenty of time to dense up. Sorry for jumping the gun.

they are a bit airy but i figured that was cause they were only 3 weeks in. the temp has never gotten over 80 in the tent. its always in the mid 70's.

Your temps are fine... The appearance of your leaves told me that much.

Yeah, I made that comment before I read that you were only three weeks in. Give it time, they'll fill in.

Looks great for only three weeks.

Peace.

ok i just checked after having the new light it and the high was 83 is that to high? i only had the fan on med so im thinking opening a window and putting the fan on high will do the trick if need be. is 83 to high? also thanks for the all the compliments and help.

83 is a little high.

For better density try to keep it under 80 in the mid to high 70's.

k thanks. shouldnt be a problem.


edit.

i shut the 2nd light off for now, its going to start being in the 30s and 40s really soon. i figure that will help. its been high 50s-60s the last few days so imma wait it out.
