if you are asking about the plant you posted two pictures of, it appears nothing is wrong with them...they are green and healthy.

Droopy leaves is usually caused by overwatering....I believe...someone with a bit more experience than my 1 year of growing can confirm or deny this however.

Hey guys, i need someones help

Im a "noob", im going to attempt to grow a crop, and basically i want to know what would happend if i had only about 2400 Lumens per sq ft?

Regards,

if u dont have enuf lights ur plants will stretch to get more lite and they will be wispy. lite ,water and nutrients (i.e. food) are the 3 most important things u have to worry about when ur first growing. so spend the extra $$$ for the lites use good water and keep the nutrients in the right ratio to start then u can get to the p.h., heat co2 and other factors u need to learn to control.

im a new-jack as well, but i did the right thing, 600W HPS cooled hood, Dig. ballets, for my closet of 3wX6dX7h,,im thinking i should be coverd with that,,so far in Veg 2 months along they look GREAT.....

Turkster..

Great Guide!

I think it's funny that you can tell who is posting just to see themself post.

Thanks for the report Slam!

Lol, yeh see what you mean, but after spending half an hour reading it all would be kind of pointless not to say thanks or anything

Ha Ha!!! I know exactly what you are saying there.

How about UVB rays spectrum lights? It is proved UVB increase THC quality and quantity. Neither CFL, MH or HPS are no UVB rays.`

Hi Again, I have found good article Pot potency
Just another proof of UV importance.

I have just finished my first week flowering. one morning I turned the light on 40mins late and on the last day of the first week 30mins late. Have I F**Ked them.

PLEASE HELP.....

light is certainly critical....it is the energy source for the building blocks and processes to happen. feed enuf light, and supplement with sufficient water, nutes, and air....and the plant will gorw. we are currently debating the uv question here....Trichomes, THC and UVB light..... .......

****EDIT**** - in my view you have not f*cked them....they just lost some potential...temporarily....

Wow tahoe. great read!!!
I have been researching this for a bit now. I was wondering the same thing myself.
I'm down to two light choices right now.
An 800 watt system that eks 2 bulbs at the same time. You can have either 2 MH, 2 hps or one of each. It has a built in fan but is also $400.
There is another 1000 watt system that takes either MH or hps but it is $350.

I like the idea of having 2 bulbs. More costly to run but I bet that would work nicely.

this search for the "perfect" analog for natural sunlight is really interesting and I believe we are still not really there. the fundamental objective of the indoor growers has been yeild and speed, and not necessarily quality. that does not mean indoor stuff is crap...it just means that if you talk to oldtimers...ok, yea I'm one, the indoor weed pales in comparison to the excellent outdoor weed we had in the 70's. then add the physics of light and a couple of other principles and you start to see where the shortfall might be coming from. integral with this discussion is the debate over the "pupose" and evolution of the trichome. this has helps us better understand the how and whys? I am one that is going to try the UV thing once I get myself better organized. I also like the idea of the double HPS/MH bulb. So in my case and for my space (currently a 400W super HPS), I will be looking to put in 2 x 250W (HPS and MH) or theere is also a single dual bulb (400W or 600W) and I will likely also add the UV (either 160W or 300W).

For whatever reason, it still just is not that simple. I was looking at a bulb called the SloarMax (1000W)...and yet when you talk to other growers they say the ones they have been using are better. But it really does come down to what ur objective is. In my case, I obviously want a decent yeild, and I don't want to wait forever for it.....but my prime objective is quality of smoke.

Good luck Lacy....
