FWIW, here is a set of gardening links that I have recently compiled. These are some garden things that I've found to be pretty helpful. If you got a recommendation of your own, add it! It'd be cool to get everyone's favorite item on the list:
Extension Bulletins:
This one tells you when to plant what. These are the dates for a transplant, not from seed.
If you are starting from seed, use the dates in the previous doc and use this to back track from there to know when to start from seed.
I like my starts a little bigger so I would pad that date by about 1-2 weeks.
LED Grow light: This is the one I bought off Amazon. Seemed to work fine last season and definitely reduced the hardening off period.
Heat mat + Temp control: This is the set I bought. It's been working fine for me the last few years.
Light hanging ratchet cord: If you aren't using these to move your lights up and down, you are trying too hard.

Garden Stakes: Just some generic strawberry/weed barrier stakes. They seem pretty high quality.

Plant tags: These are industrial, no rust tags made out of aluminum. You can just write on them with a pen and it will emboss whatever you write. This is my first year trying them.

Potting Soil: Mark J told me about this one. It's a huge cube of potting soil for $25. It fills up one of those galvanized old timey trash cans. Great deal and pretty decent quality although, complete disclosue, some herbs I started in it came up a little sickly. Still, for the money, this is what I'm going to use.

Thermometer: This thing is fantastic for under $20. I left it outside in my soil for two years straight and it still works great.
