24 hour seed cycle?

*Puts on flame suit*

I have been doing my research on here. I have looked at the stickies and they were VERY helpful.

I use: 6 cfl 26watt 5600k. Temps are always perfect since I have a couple fans (One big intake and 2 small exhaust). Only have 2 plants.

The only question I have is...are you able to leave the lights on for 24 hours after planting the seed? Maybe for couple weeks then 18/6? I seriously could not find a definate answer.

A buddy of mine has a clone (which are about 10'' tall) and is also telling me to put it under 24 hour light for about another month then 12/12. With the research I did..It didnt make sense.

Any response will help. Thanks alot guys

Bump for me

a lot of people do use 24 hour light for the first few weeks i know i do.

I have read though that a plant can only really process 18 hours of light and many important reactions take place at night.

I can't remember where but I read once that a plant will grow its most within 4 hours of having lights on after an 8 hour dark period.

So in general let your plants sleep. 24 hours is fine for the first few weeks but sleep is very important too, unless your growing a dwarf in which case i have heard 20/4 is the best way from start to end

Thanks I appreciate it. That makes alot of sense now.

I forgot to mention the seeds were not purchased so Im not expecting to much (even though Ive been told "female seed this and that if u see one in your bud" but I thought id test it with all the right elements and testing measures and make sure everything is correct (ph, temp, soil etc. Like I said..plenty of reading just a few odd balls lol)

I understand plants need some sleep ( I would figure..just like us we need some shut eye - to much light for just a little seedling seemed like it would scare it but then again im using cfl so who knows).

Im going to try 24 on for the first week or so and see what happens. If I see some good process Ill change it again.

Doesnt suck to try when its cheap

I cant thank ya enough. Take care.

Any more suggestion is welcomed. Thanks for ur patience guys.

What about clone? any input on that?

Okay so the big debate here we go:

24/0 is good if you are on a time sensitive grow and need to flower earlier than expected. The only problem with 24/0 is the roots will not develope as fast as the canopy, but will catch up during 12/12

18/6 is great for a grower who has all the time in the world, and can acheive proper root and canopy growth all in one.

Plants in "veg" do not need a night cycle, it is only important when plants are flowering. Another good thing about 18/6 is you save 6 hours of electricity.

For clones the photoperiod should definitly be 18/6 since you have taken a cutting and need proper root growth.

Only to a point. Depending on the particular genetics of a plant the roots will only continue to grow for a certain amount of time once in flower. So the roots may catch up enough and they may not catch up enough and if not that leaves your plant with an insufficient root system to rely on for maximum production or even to remain healthy as it otherwise would be. That is one reason I never liked the 24/0 light cycle.

Without vigorous efficient roots you do not have a vigorous efficient plant. What is below the soil is actually way more important than what is above the soil.

I will give you that brick, but then again this is why we have super thrive and big bloom for veg, am I not right????

Roots always stay proportionate to the plant NO MATTER WHAT. Thats why you can restrict grow by root pruning, its called bonsai. Cannabis is a c3 plant so it basically means that it does not need a lights out period. There was a study and it showed that the best schedule is 20/4 one that people really dont use. There was hardly a diff between 18/6 and 24/0. During the night the plant grows, and during the day it absorbs light energy. It can do them both at the same time but its more effective when they can be separated, even just a little.

If you trim the canopy, the plant will actually halt root production until the canopy catches up. When re vegging, you dont create more root mass, it simply just regenerates the old roots that die naturally here and there.

Its odd how just a little amount of day light or lights out makes such a diff (20/4 and 18/6 for example) I can understand a 24 hour function for vegging but Im going to try 20/4 and see what happens. Im baked and cant really decide and would hate to fuck up the light schedule.

You guys are very helpful twist one
