lighting times help needed

yeah my 12/12 is starting at 2pm dont ask me why

really i need to change it so the lights come on when its coldest

so was thinking on from 7pm until 7am

so i need to change my dawn :S is it advisable and if so should i just shock them with a 5 hour dawn shift or gradually do it ?

thanx

5 hours shock will do no harm whatsoever - reset your timers now, they still got 8-10 weeks to go

It is better to leave then in dark longer than give then longer light. So when lights are out reset the timers no big deal.

Agree with both my fellow growers

It will have no effect to switch the time


BUT .... It's good that your thinking like this

I was in the same shit as your in.
No it will do nothing what so ever.
Just dont OVER do it.

dark for longer in 12/12 no issues, other way round only in emergencies

ps same shit, using fan heater at mo 2 keep temps right

gr8 info thanx people. So lights coming off in 40 mins - i will now leave them off until 7am, so they will recieve 1 dose of 17 hours darness tommorrow and then i will be able to leave my new dawn set at 7am

nice ol bud said will do nothing but dont over do it - by this i assume he ment dont cock up your timiings again - 1 mistake not too bad but more could be an issue :S right?

ps skicky bob i decided against a fan heater and went with a 1kw oil filled rad heater (electric) because i was conserned about the dry heat fans give off - sucking up any humidity. i might have been wrong but this was my thinking.

thanx again all gr8 help

i thought about that, but with a 60l tray flooding and draining humidity seems to stay pretty bang on maybe would cause issues with soil.
