Knowing I was off for a week for Julie's birthday I wanted to get some of my indoor seeds started while I was away. That was a week ago yesterday (Tues 13th).
I'd been to the garden centre in the afternoon and bought a seed tray (which I was surprised to find has holes in the base - so I'm a little concerned about over-watering), a seed tray insert of the biggest size (15 cells to a tray), a clear lid, some potting compost and my first seeds to plant.

I'd chosen my
tomatoes, Moneymaker (normal size) and
Gardener's Delight (cherry). They both want starting indoors in Apr/May, so that's still fine.
For my
brussel sprouts I've gone with
Maximus (harvest Oct-Dec) and
Petrus (harvest Jan-Mar). I'm impressed that they both sound like Roman Gladiators. I wonder if they'll be as hardy? They are supposed to be started indoors in Feb/Mar, and sown direct outdoors in Mar/Apr. I decided to try some indoors and plant them out at the same time I sow the outdoors ones and see what works.
I've also bought some
leeks (they didn't need starting indoors, but I'd researched which I wanted so bought them at the same time). I'm going to try
Oarsman (harvest Oct-Jan) and
Musselburgh (harvest Nov-Feb). As with all my veg, I'm selecting the most common for beginners - which usually mean they are hardy and give a good crop... experimenting with flavours and the like can come
after I've managed some in the first place :)
First thing was to prepare the tray. Popping one inside the other I filled the cells with the compost - which was very light. I'm sure I'd read to compact it a little, so I did that by hand in each cell, and then filling it to the top again. I didn't know how much water to put in - the lady in the garden centre had warned that over-watering is common, and the roots get too soggy and die. So I opted for using my old plant sprayer... which is probably what it's supposed to be used for anyway. Spraying was a bit hit and miss, literally, as you can't spray-down into each cell directly, and for those near the edge to get enough entails soaking outside the tray. Ah well, job done.

Next was opening the packets. Never having done this before I was really cautious in carefully peeling off the base of the first packet so as not to spill any seeds... only to find that they're actually contained in another packet inside the first! Next year I'm sure I'll look back on this and laugh - but if no one's told you it's the sort of thing you wouldn't know :/

The sprouts handily told me that there were 15 seeds in each pack, and I'd already read that they come with all the things they need in a special coating - that is coloured blue so that you know - so that they have a much higher chance of sprouting (so to speak). I was planning on putting one per cell, and 2 cells of each and seeing what developed.
I had no idea how many tomato seeds there were in each - and what the chances of any of them sprouting would be. It turned out to be about 50 of the Gardener's Delight, and about 100 of the Moneymaker. I only want 3 plants - 1 cherry (GD) and 2 normal (Mm) - so I opted for 2 cells of each, with 2 seeds of GD, and 3 of Mm per cell - with the intention of 'picking them out', or whatever the "culling of the least good" phrase is.

I put each on top of the compost and scattered a bit more (maybe just a mm or two) on top, and then watered with the mister again.
I made myself little paper labels. These have already gotten a little soggy since with the condensation - so for the next ones perhaps I'll get some plastic ones, which I seem to remember having seen in other people's greenhouses in the past.
I put the cover on and put the whole lot on the front upstairs windowsill - which is south facing and gets the sun most of the day.
The interesting bit will be the temperature. The tomatoes want 18-20 deg, and the sprouts want 10-15 deg. Fortunately the weather forecast was sunny for the week I was away, but it was going to be 'suck-it-and-see'... which I'm sure will be the first of many times with this veg growing thing :)
Finally it says to keep the seeds dry, and in an airtight container in a cool place. So the last thing I did was to find a handy Lock&Lock container where they are now nicely stored.
So, with all that - the first seeds were under way, with me not having the first clue as to what would happen next!...
