Advice is needed and appreciated

UHHHMMMM yeah! Plants will not react well to a schedule of light that goes from 18-6 or something to 24-0 then to 12-12... They will see the jump up in the length of daylight and believe it is early in the season (when the days are still getting longer) and then you're gonna go to 12-12 and they're still going to veg for a while before realizing it is time to flower. This stress on a plant can cause you to get hermaphrodites if you aren't careful. On top of that 24-0 IMOOOO is never a good idea because plants need to respire at night. Sure they will grow at 24-0, but how would you like to work and work and work in the heat without your body producing sweat to cool you down? That is essentially what plants do at night- sweat. Honestly i would go 20-4 at most, then either drop to 18-6 before flower or just go straight to 12-12 at flower.

As for the transplant... yeah the roots are exploring the newly introduced space, that is what the plant is spending it's energy on. Once the roots are broken into the new soil growing will resume and possibly increase in rate, depending on how they take to the sudden increase in light.

completly wrong informantion....there has never been any scientific evidence to prove that a 18-6 cycle is better than a 24.....if the energy is available then 24 is the way to go.....

Photosynthesis occurs mostly at night. This has been proven by science and nature. 18/6 ftw

a good thing to remember is that at night your plant will stretch in search of light... if you run a 24-0 your plant will stay shorter and stockier

Hey guys i have a question. i have a 4x4x87 grow tent running 600W HPS, Heat usually inst a problem with my window AC unit but sometimes it is. Is 400W enough for a successful and hearty harvest/yield?

irrelevant.... do your research....there has never been any scientific evidence that allows the argument to have a better results....some people prefer 18-6 some 20-4 and some 24-0 .... i keep mine on 24 because i like to be in my grow room at all times of the day and night....(unless there flowering)....the only benefit to having a 18-6 is to save electricity.....if your running 4-1000w lights u might want to shut them down for a few hours....if your running florescent....keep them on!....

Try not to intrude on someone else's thread man, it's rude. Start your own thread and im sure we will be happy to oblige.

how many plants are u having? remember the more light the more yield... i have 6 plants and run a 600w hps...and i also have cfls on the sides to illuminate the sides of the plants and get some light underneath the canopy... but you should start you own thread...someone else is trying to get an answer here too lol

do more research


marijuana needs no dark period until flowering....
The 18/6 photo period expels 3/4 the amount of light that a 24/0 photo period does. Although this does not mean that a plant produces 1/4 less leaves,branches and nodes under the 18/6 photo period, it certainly does show the correlation between light and cannabis growth., cannabis is a light demanding plant. There are no problems associated with 24/0 it does not need a "resting time"

Let Us Fuck!

I've done plenty of research on the matter. Plants do transpire and photosynthesize at night no matter what studies prove otherwise.

OK. Research done, plants 'eat' at night and break down those sugars from feeding using oxygen. They then use that fuel to produce chlorophyll. The focus of the plant during the day is to absorb light and increase the size of the leaves (to better absorb more light), whereas the focus at night is to eat and reach. The process that plants 'eat' via is called transpiration (the passage of water through a plant from the rootsthrough the vascular system to the atmosphere).

so what your saying is plants need dark to photosynthesize??? you do know that photosynthesis is the plant TAKING LIGHT and turning it into energy? plants photosynthesize during the day

transpiring occurs then water leaves the plant by exiting thru the leaves............. thats one of the reasons why you keep a fan you ur plants not just to keep them cool....

BOTTOM LINE YOUR PLANT WILL STRETCH AT NIGHT WHEN ITS SEARCHING FOR LIGHT......IF YOU KEEP THEM ON 24-0 U WILL GET SHORTER STOCKIER BUdS....THATS THE ONLY KNOWN FACT PROVEN BY ANY SCIENTIFIC GROUP....... its all to each his own...what ever works for u works for u..

And why you're supposed to keep air flow at night. Transpiration occurs mostly at night. That is what plants DO at night. 24-0 does not occur naturally ANYWHERE in the world suitable for cannabis to survive. That is all that I am saying. My preference is allowing the plant to go through it's normal processes as it would in nature regardless of whether or not the cannabis plant CAN survive in a controlled environment where 24-0 exists. Just because something DOES work does not mean it was ever meant to.

And yes, that IS what photosynthesis is. But the primary function of the daytime portion of a plant's day is to absorb and focus only on absorbing... At night it focuses on using that energy along with fuel that it takes in to produce chlorophyll. End of story.

think of it this way........remember how your parents or older people u might know say things like "weed today is much stronger" thats true in a way...the levels of htc in plants hasnt really increased..but the strains and the ease of getting high potency is because of UNNATURAL THINGS------like using a very good grow medium.. using nutes..things like that...it may not be the way nature intended and nature may be able to grow marijuana on its own....but thru out the years.. people learned how to prefect it...things like 24-0 light cycles ect its all in the name of growing weed...people will argue this conversation over and over and over probably many years from now.. i just do what i do because it works great and keeps me having more branches and shorter plants.
