which 14/10 or 12/12 works best for yall?

[The Hemp Goddess]

some people said 10/14 to get more ratio of females? true or false?

less lights to get them pre flowering the last grow we did was 12/12 we got 40 percents of males 20 percents of hermies, maybe its from the seed strains?

False.

If you got 20% hermies, something is wrong--most likely either seeds from hermies or light problems. I would not screw around with 10/14 or any other weird lighting regime when your plants are in flower.

Anything you do to try and get more females has to start when your plants are in veg and have several sets of true leaves--about 3 weeks. These things include: More nitrogen, less potassium; higher humidity;lower temps; more blue light; fewer hours of light (18 instead of 24); NO stress. Continue for several weeks.

thank you everybody, yeah 18/6 does make sense to start with.. and its better to do so.... after the sexs starts to develop, will need to flip it to 12/12
with HPS right?

 

[Timmyjg6]

Yes, iv never herd of any one using any thing other than 12/12 for flower and anywhere from 18-6 to 24-0 for veg. I would stay in those lines..

 

[godspeedsuckah]

12/12 don't stray.

This is another strain dependant thing.. Hardcore sativa growers will mimick equatorial light as much as possible, vegging at something like 13/11, and flowering at 11/13.. Environment can matter alot as far as pheno expression goes.. Indicas do like the whole 18/6 or higher for vegging, but you can also pull more sativa out of them at times by showing them the equatorial environment..

Vegging at 13/11 doesn't make them just go straight into flower? Seems awful close to 12/12.

the "key" words I_love'.. is "equatorial sativas"...
the light hours are a consistant 12/12 on the equator.
Therefore, plants native to that region are 'climatized' to those confitions.

 

[i_love_amsterdam]

I figured that was probly it but i'd never really heard that before

 

[DomsChron]

I read a thread on here a few times explaining how plants flower, and they do it like this. When the chlorophyll in the leaves are hit by light in the correct growing spectrum, they produce a chemical florigen. When there is NO light, antiflorigen is produced. So it's important to stay at 12/12 because plants flower when the ratio of florigen to antiflorigen is equal. By the way, remember to keep those 12 hrs DARK because, and I quote Hick, antiflorigen isn't created by a lack of light, it's created by the ABSENCE of light

 

[papabeach1]

DomChom....

you are correct... just like all vegetable plants... they bloom in 12/12

I never see any bloom in 24 hours which absence the dark period of blooms..

I would stick 18/6 for females... I don't care about males they can live with 12/12.. but for mothers to keep... 24 hours is great!! that is where we can absence the bloom time.. and keep them up to 5 to 12 years depends the conditions of plants.. and have many donors as we can cuts.. also tomatoes seem fussy when I put them on 24 hours.. they grows alot better in 12/12... strange?.. hmm..

 

[DomsChron]

I disagree with only 1 thing you said man. Where you say 24/0 is good for a mother to keep or something? You see, the Cannabis plant literally can only receive max 18 of those hrs a day, so any more won't help anyways. Plus, a dark period id beneficial because of root growth. The dark period also lessens chances of those darn HERMIES!

so 18/6 for MOMS?

 

[DomsChron]

18/6 for ANY plant, they wont EVER use those extra 6 hours. So convert it into an UNDISTURBED dark period.

..At "best".. a subject of contraversy.
"I" personally am of the school that believes plants will use as many hours of light as they are permitted.
They DO NOT require/need a dark period..

I keep my donors/mothers on strict 24/0. I keep them for years on end in that manner, with "0" ill effects

 

[massproducer]

Yeah, i hear this coming up now a lot but I have yet to see ANY concreate information stating that a plant can only use 18 hours... I on the contrary find many scientific pointing to the fact that plants do not require a dark period during vegetative growth, as everything that can be done during the dark can be done during the light, but it is also a fact that during the dark period a plant can not generate any additional energy because it obtains energy through photosynthesis, which requires light.

You have to understand the difference between light-dependant reactions and light independent reactions in plants.

Everything credible sounding, that I have read, leads me to believe that the max light hours are tied with intensity..
Not that photons won't be absorbed after that many hours, but that photon absorbtion beyond the red-line can be destructive to the chloroplasts..
See photosynthesis doesn't just turn on like a light, it builds up like a fire.. Throughout the day, more and more electrons get bumped up, and stuck in triplet state waiting for water/CO2 to process.. In intense light, there comes a point during the day where there are more excited electrons than there is water/CO2.. When this happens, those electrons end up participating in undesrible reactions.. Doing things like using O2 to create superoxides, and other toxic crap that destroy chlorophyls/chloroplasts..
This has nothing to do with hormone balance, its more analogous to running an engine too hard for too long.. Where this red-line sits depends on the plant, temperature, humidity and CO2 levels.. I have a pretty hardcore indepth biochem pdf file outlining PS1, PS2, and the Calvin Benson Cycle.. If anybody is interested, let me know how to send it, its ~1.2MB (30pgs)..

I do see your point about "burning leaves" from HPS/HID lights if runs just 24/0 (IMO that what you talking about) but floursec. lights/cfls does not hurt the plants as HPS/HID does if you runs it on 24/0... eventhough that kind of lights do gives little co2 toward to the leaves/stems (green parts of plants) which the chloroph would be happy IMO... also about these superoxides would be storage in the plant until the donors is made.. along with nutes.. that is where we do not need to give nutes to donors for 2 weeks...so they can grow roots.. by the time roots grows.... it is time to give them new nutes and flip it to 12/12.. so.. If these superoxides/co2/oxgen wasn't provided in the mom plants... then I do not think clones would be success? maybe I'm wrong with these.. I'm just trying my best think myself as marijauna plant... and feel what they are feeling

 

[papabeach1]

thank you very much hick and massprod to point that out that I do not need dark period.. because If I did has them in 6 hours of dark period.. they would grow some preflowers... and maybe I can't get more donors out of mom plant if that occurs.... as hick said.. he grew mom plant and kept the plants 24/0 and have no problem.... I would go where plants has walked the talk..
marijuana mom plants can survives with no dark period of time until you decide to stop doing the clones. you can just put the mom in 12/12 just to end the donors..and get what you have remain from the plant itself.. IMO the energy comes from light rays/par and produce the sugar so that means we got everlasting of THC as they are producing!! just my IMO anyone please correct me thanks..

Umm.... I don't understand you, and I'm pretty positive you didn't understand me..

Umm.... I don't understand you, and I'm pretty positive you didn't understand me..

okay give me the link or send me pm to get the link of that pdf files on grow cycles... I will take look at it...

just that I do trust nature and let it grow outside... the only thing I grow indoor is to have a lot of donors and "sog" these donors in DWC if I do grow it lot better and so far we have handled lot better than deal with 9 to 12 months of grow cycle.. its more advanced to me.. and I like it...

also plant did walked the talk... plants did like 24/0 for years... 5 years.. 12 years.. not bad... no wrinkle leaves.. so far I grew lot from CFLS I see no burns...no retard leaves.. just nute burns it happen sometime that's all..
help me out to understand you please...:hubba: I ll be back in few after clean install of black xp pro sp3 vista style

Anybody who wants it post/pm an email that can receive a 1.2MB pdf file..
I don't really want to make my webserver public on here..
Fair warning though, it is not an easy read, and the chemistry is VERY indepth..
