Light spectrum change, transplanting and light cycle switching.

Hi Mates,

Looking for some advise on Light spectrum change, transplanting and light cycle switching.

I have just finished my first harvest and now am moving my 5 week old topped white widdow`s(x6) into the flowering room from the veg growdrobe.

I moved them from the growdrobe that had 4 large CFL`s into a closet with a 250w HPS, also I want to transplant then switch to 12/12.

So far I moved themunder the 250w HPS two days ago.

FYI: I have yet to sex these plants and not sure exactly when I should be seeing pre-flowers?

Some pics of the topped white widdows:


Here is a pic of the closet with the 4 CFL`s they came from:


Pic of my homemade air-buckets


Here are the AK-47 seedlings for after the white widdow`s:


My question is how long should I give them between these changes so as not to stress them too badly?

All tops are 8-12 inchs from the bulb, is this too close?

How long till I can transplant from my 1.5gal homemade air buckets to my 5gal homemade air buckets?

How long after that until I can switch the light cycle to 12/12?

Or do you think I should just go ahead with the rest without giving time in between these changes?

Thanks in advance for the help and suggestions, much appreciated!

Bumpin it up, come on people, please help here.

all looks good enough to me, when u introduce ur MH light put in a good 20 inches above the canopy and bring it down every couple of nights inch by inch, kepp bringing it down till ur plants get enough light or look heat stressed*( slight turning up of leaf edges , on the last 3 weeks id do this- as close as possible 600w about 16inchs away roughly
... u ask alot of Q's
let the roots be well noticed /coming out of the bottom b4 transplantin
switch when u want for seeds about 8 inches
