well curentaly im on 12-12 and its of from 12 pm -12 am but im haveing light comming in from the door so would it stress teh plants to much if i changed the lighttimer to say 8 am -8pm? or should i just buy somthing to fix o btw they have been in flowering for 40 days today

No problem....I switch cycles about twice a year my self. Just run an extra dark period to start the new lights on cycle and you should be fine.

quite a coincidence, I had to do the same thing a few days ago, completely reversed my 12/12, ... so far, no obvious ill effects ... :smokin:

When im on 18/6 i have it off from 12 pm to 6 am.

When im on 12/12 i have it from 9 pm till 9 am.

Though id share, altohugh try and do your best to cover any larger cracks.

Got any pics man, if i remember rightly your plants are quite nice.

ahhh was just about to post a thread asking this so may as welll do it now lol. My lights are on from 8 am to 8pm but with the temp rising here i was wanting to change to 8pm to 8 amcould i just leave the lights on for extra 12 hours or leave it dark for extra 12 hours to make this change? and what affect will this have on the plants they are 46 days into flower.Or will the temp rising into the 90s for 5 hours a day not make any difference at this stage.the postman.

There is no affect on the plant with an extra dark cycle. They don't react that quick to light changes so it's fine.

I did it myself the last round with only 10 days left and had no negative affect I could tell.
