Don't let temps drop below about 15°C.. Beyond that how are we supposed to know what the temps in your growspace are..

I am running pretty darn cool right now, trying to keep a bug problem down until harvest in a few weeks...

Would you be able to elaborate a little more on the detriments of growing at low temps...

I'll get things warm again, but right now I am trying to get to slow down/hibernate..

lights on is 65F/18C...

lights off is 50F/10C..


I would appreciate your comments...:-P

Yup yup...I'm a general contractor...they are in fact all over large construction sites.

HOWEVER I HIGHLY DISCOURAGE STEALING FROM CONSTRUCTION SITES...IT'S DARK, THERE'S NO ONE AROUND...THEIVES THAT ARE CAUGHT ARE GENERALLY DEALT WITH SEVERLY WHEN CAUGHT IN DARK PLACES WITH NO WITNESSES.

BESIDES IT'S JUST FAWKING WRONG TO STEAL AND ALMOST AS WRONG TO CONDONE OR SUGGEST IT. BAD FORM MY FRIEND, BAD FORM!!!!!!

and on a more personal note...thanks, it's people like you that cost me hundreds of thousands of dollars a year replacing crap I find stolen, you know we can't work when you steal our stuff?!!?!?! Oh and those lights, that's called EGRESS LIGHTING, it's sole purpose is so we don't trip and kill ourselves at 5am when the fawking sun isn't even up yet. And when it's not in place OSHA comes and shuts down our job site because we are then in violation of federally mandated construction safety laws!!! Makes me sick when I have to be woken up by my Foreman because someone stole from our job site!!!!

YOU WANNA GROW POT FINE...DON'T STEAL FROM HARDWORKING PEOPLE TO DO IT!!!!!!!!!!!!!!

Question:
So i am about 3 weeks into my flowering cycle and due to me moving at the end of the month to a different state, i only have 4 more weeks of flowering i can do. I'm worried my plant wont be ripe in time. is there any way to speed up flowering? I heard cutting back the light even more from 12/12 to 10light/14 dark would help is this true and by how much? From what i have seen in books and pictures the plants seem to be advancing fast almost look like they have been flowering for 4-5 weeks. any thoughts or suggestions? thanks!!

Thanks for the heads up. I did some reading and it seemed like most of the problems were because of incorrect bulbs being used in them. hydro wholesale assured me they matched the correct bulbs to the 1000w dimable/dual voltage/switchable lumatek ballast and it's little sister the 400w ballast that arrived in the mail yesterday. I also got two yield master 2 hoods and some other goodies. Sweeeeeeet I will take some pics when I get it up and running. :)

What if for the first 3 weeks of growth from seed, lighting sched. has been a couple days of full light then 6 hours dark couple days full light 4 hours dark for 3 weeks.. starting today ill make sure they stay on 18-6 daily but but just curious if i for sure botched my plants or not. i was just impressed with the growth i was getting.

Won't intrinsically hurt them, under strong light though plants need a bit of dark on a daily basis to use the light most efficiently.. See photosynthesis builds like a fire each day, it doesn't switch on like a light, there are dark cycle processes (that also occur in light to a lesser extent).. Basically what I'm saying is that there are equilibria that need to be maintained if you want to get the most out of your watts..

During hours of light plants multitask, they perform all their various functions at once and to do that they allocate energy for each function.

Even under full light plants can only take in so much energy so there is of course a limited amount to divide and what that means is all functions receive a small amount of energy to use.
　
During hours of darkness plants run on stored energy, energy that was tapped off the energy taken in during the day while the plant was multitasking, and because of the limited amount of energy shuts down all but the most important most needed most vital functions, it stops multitasking.

It throws all its stored energy into just a few vital functions and because of that they receive a greater amount of energy for their functions than they do during hours of light.
　
Growth and THC production both are part of the vital functions carried out at night and that receive an increased amount of stored energy over the amount of lower daylight hours amount of energy they receive.
　
That means those functions are carried out more efficiently during hours of darkness than during hours of light.
　
That is why I never believed in the 24/0 light cycle. Plants grow more efficiently at night than they do during the day so what is gained by taking away their nights?

Anyone heard anything or tried the 1000W Sodium/Halide Dual Super Blue Arc Tube as opposed to the regular 1000W HPS? PM if you can also cause I am so many places on RIU that I don't know that I will remember to come back and check. That darn short term memory.

I have some 3' Big Bud with 1000 watt light on 18/6. I have nice groth at every node. Now I am going to flush and start them on Fox Farm Big Bloom Should I change the lighting to 12/12?

I myself start giving them 1/4 str. of the flowering nuts. with my veg nuts. a week or so before i start the 12/12 hours of light.

But that is just me, do whatever works best for you but if i was you i would for sure be giving then the boom nuts.:bigjoint:

How does growing under a red spectre light from start to crop effect the growth?
Click to expand...
it wont be as compact and bushy as it would be under a blue spectrum light, so its always good to start off with mh (blue) and flower with hps(orange redish) that way with the blue it will be compact and very bushy and then with red it will help the buds flower nice:eyesmoke: and if you can do both from start to finish it will be perfect.

ive made the mistake of growing with a single 50 watt bulb. my grow has been extremely slow. and i cant find another buld or fixture to substitute it at my local lowes/home depot. after nearly 3 months of growing i just reached the first signs of budding (small white hairs). and i have a smaller grow area (only room for one plant). if there is any suggestions you guys have i would really appreciate them. thanks.
