light times for veg cycle

[issack]

i was told to run my clones after they root for 24 hours untill i get my hight and then go to 12/12. i noticed alot of you are going 18/6. in my eyes i think the plants need alittle rest. should i switch to 18/6 now? or will that affect things as i have already been running 24 for a week now. my clones are off to a slow start. i think they were stressed from the delivery to my house.but they are comming around now...thank god!!!. but i do think they need some rest.will moving to 18/6 slow my veg time since i've been going 24s? i NEED some imput today so i can make the change when i get home....THANKS GUYS!!! ALOHA....

Hey Issack and welcome to ICMag, my brotha! To answer your question, Yes, you can go to 18/6 for veg. I also choose to veg at 18/6 as there is some scientific basis that the plants do well with a rest period. Since you have them at 24/0 now, I wouldn't just drop the lights to 18/6 all at once. Rather, you could reduce light times by an hour or two everyday until you're at 18/6. This will give your plants a gradual reduction to ease them into it. Hope this helps!

u can do whatever u feel is better for u & your plants 20/4 or 18/6 also depending on whether electic bill cost is a concern to u or not. I am doing 24/0 atm they grow VISIBLY FASTER always give lights at least 15 min rest a week though Welcome 2 IC .Later Big

when my Veg room was a bunch of fluor. lights I used 24/0...

now that its one 400wt MH I use 19/5....since its good to give HID lights a rest period...


both worked for me


but it really depends on what works best for you and your setup

What is the best light cycle during the vegetative stage, 18/6 or 24/?

And which one will help the ladies go into their flowering cycle with the less stress?

Marijuana plants photosynthesize as long as they receive light as well as water, air, nutrients and suitable temperature. Photosynthesis is the process in which plants use the energy from light (primarily in the blue and red spectrums) to combine carbon dioxide (CO2) from the air and water (H2O) to make sugar while releasing oxygen to the air.

Plants use sugars continuously to fuel metabolic processes (living) as well as for tissue building. The plant combines nitrogen (N) with the sugar to make amino acids, the building blocks of proteins. They are the substance of plant tissue. When the light is off, the plant's metabolic processes, respiration and growth, continue.

The plant can photosynthesize continuously so it produces the most energy and growth when the light is on, continuously. Continuous light does not stress the plant, which reacts somewhat mechanistically to it.

Plants under an 18-6 light-dark regimen are producing sugar only three quarters of the time. They are thus growing at only 75% of their potential. Leaving the light on continuously will result in bigger plants, faster, which leads to higher yields. - Ask Ed
