Timer settings for lights for growing seedlings

 I bought a "Powerplant" hood and 2 off "Ecolight" lamps to go with
them and and timer switch for germinating alder seeds and growing them
up as fast as possible.

Now I look at the timer switch, it gives a fixed 12hrs of switch/day
and there is no provision for changing it. I am a little surprised at
this, really, I hadn't thought about it and I should have done. What
is best? I would like to read some discussion.

This set-up will not be in a green house and the hood will not be hung
from above, it will be in a living-room (at living-room temperature)
and I have enclosed the seed-tray and lights in a box, so when the
lights are switched off, it will be dark, unlike when a hood is hung
in a greenhouse.

Perchance the gadget has a perma-on position as opposed to timer setting,
then you could plug it in via an external (£3) timer and set the offs and
ons to your hearts content.

Otherwise it sounds like cover off time and bypass the internal timer and
use the external timer.

Oh yes, there is a "permanently on" switch, but do you advise me to
use it?

No reason why not to, that I can think of.
You can get the desired off periods with the external timer.

If you could give me product reference source  for this "Powerplant"
then this would help.

Aldi have some timers on special offer, you could consider

So far as I be sure from pictures on the web, this is the hood:-

and this is the light bulb.

I can easily handle the electrics of it, my question is "how many
hours a day should the lights be on"?

I am a complete newbie in this. This is my first attempt at growing
seedlings under lights.

Thank you for any advice, it may seem obvious things to you, but it's
not to me.
