The £22 light is great.... :) one of the seeds popped up on saturday so i bit the bullet and decided to put both the trays under the light... and now ive got 14 out of 30 though and there growing about half an inch a day!.... 8) looks like the rest will be though by tomorrow..  :)

If you get a light make a growing box like me....
you could do it the cheap way and buy a pvc storege box and line the sides with tin foil to optimise good light around inside, and attach the light to the lid.... make sure you buy a big one, (Which i should of realised) to fit your seed trays or heatedpropagator in and to house the plants when you pot them on as this is were they'll need to stay till around march...:)

Interesting post this one. Having tried the normal lights like Jamie, I found that the plants became 'leggy' looking for light. So I did a bit of tinternet research to see what I needed to do and it seems that the main source of light needed for growing is the blue light spectrum. The price of the grow lights was a bit more than I was prepared to pay and the area covered was very small, to get something to cover what I needed was a re-mortgage job. Anyway, I found a company that sold fluorescent tubes that only gave out the blue light spectrum so I ordered some 4ft tubes. They fit in an ordinary fluorescent light fitting and I made some up. This was last year and the results were really good. With a timer on them to come on an hour before and go off an hour after normal daylight hours, increasing the total time weekly, I had no leggy plants and had some of my best plants ever. I will be doing exactly the same again this year.
      Jamie, when the onion seedlings and other bits I have promised you are ready, if you can manage to pick them up yourself, I will show you my set up and I will have a couple of tubes spare if you want to try them. If you can't pick them up, as I said before, don't worry I can drop them off for you.

My onions are through :D

Ive been thinking, if just a normal lamp is too far up the yelow side of the spectrum, would it be possible to attach some blue plastic under the light so the onions would get blue light? :unsure:

That won't work Jamie.

You can't make blue light that's not there. All you'd do is filter out the yellow and only let through the little blue there is in the first place.
Did it really tell you to do THAT on the packet?

Seeds are SOWN, planting's for plants (and bulbs & tubers)!

I can remember it from 42 years ago!

But I also had the advantage of doing a 6 year student apprenticeship at Thorn Lighting. (Now deceased  :( )

Right, they have been growing away nicely for a while now and have all come through, they are all about 7cm high and looking realy healthy, they have just had natural light.

What is the next step, do they need potting onto there own individual pots?

Im dead proud of them so far, i think they have the potential to win the local show :D :D :D

I have just pricked mine out into 3" pots of John Innes No 2 potting compost. They will be given twelve hours of light per day at about 55 deg f.
Sets a low standard and fails to achieve it.

how do you support the stems of the young plant? i'm looking into some heath-robinson affair so they're not toppling at the weak and spindly phase.
