old thread ....so anyone come up with any solid solutions?

I have essentially the same problem, and I'm adopting the same solution. I germinated seeds in early January and have had them in 16/8 lighting since then. Today I moved them into a greenhouse. They will be getting supplemental light for 5 hours/night from around 6:00 pm to 11:00pm. I'm using four 40w fluorescent bulbs for this purpose. I intend to keep them under this lighting regimen until mid April when I will turn the supplemental lighting offnd let them flower. I hope to have them finished by mid to late june.

Aspirin mixed with water is the same stuff as scorpion juice from advanced nutrients. It creates a systemic response and heightens the plants abilities to fight diseases and pathogens.

I have no ideas about early flower and such, I've never had a problem with it + I grow mostly autos now.

Hey Iceman and everyone,

Years ago I had this problem but I have learned what I believe are the answers to your question, at least in my world. We all live in our own worlds however.


Timing when a clone is taken is one of the most critical factors. Clones for outdoor growing should be taken from the mother plant in late march/ 1st of april, to be ready by the first weeks of may to set out. My experience has been a simple lesson. The longer the clones are indoors, the more likelyhood that they will flower prematurely when set outdoors. I have never had a clone try to flower that was taken from the mother, rooted under 24 for 2 weeks and then turned to normal light, mimmicking outdoors. The clones hit the outdoors as soon as they have a simple root system. The photoperiod for the clone should remain constant and reflective of outdoor light. Any attempt to increase the light beyond natural levels will result in problems. Attempts to pregrow clones to a certain size before placing them outdoors always results in problems in my view. Root them and hit the door at the first opportunity.
There is also a significant difference in clones taken from a mother started this year and clones taken from a mother that overwintered. The clones taken from the overwintering mom have a much greater tendency to flower prematurely with photoperiod change. Take clones from a seed you started in January and problems should be less.

Photoperiod stability is the key. Put them on natual times the minute u see a root.

My 2 cents.

I had no preflowering...until I turned the lights off on the solstice

This year I'll have my lights on a schedule to match the sunrise/ sunset in my area on the solstice and run them until then.

silverback killer advice bro...thanks man!

agreed with taking clones from 1 of april on, for ready for transplant clones 1 of may ... but why not root clones under 15hrs light 9hrs night(just like the photoperiod diet for rooting of seedlings in nature), like that when planted outside rootbound or not, natural light is only augmenting ... they then should not triger(I hope 'coz that's what i'm gearing to do)

^^^ I think that would work with most strains, but some of these elite clones like to trigger on remarkably long hours...

...also, don't forget light intensity and, independently, the length of the difference (ie switching from 24 to even 18 will trigger most strains). One year I hid my starts in the trees and had them trigger even though the actual day length was fine...I just didn't have enough light coming to them to keep them veg'ing.

That is a good anser Butte ... Thank you for taking the time to think about this ...

Allow me to dissect your points for analyses ..

-Light intensity-> more lumens to keep in vedge --> I agree with your thought
-Light length of difference-> triggering occures with full plants-->the devil's advocate asks the embrion question "is a clone a plante before it has roots?" and there for may it have a "fresh" start under 15/9 ?

thank you
