I decided to buy a shelf for my seed starting area rather than build something. My time is pretty precious right now and I found this awesome deal on amazon.com. This shelf was only $29 dollars, and it is nice and sturdy. It was so easy to put together too. I wish I would have bought a couple of these units because now the price is listed at almost $50. The beauty of it is that even through it is almost 5 feet tall with all four shelves, you can make it smaller if you need to, which is what I did. I only needed three shelves to fit under my cabinet.
I have moved my seedlings under my grow light for the last few days. I had several tomatoes germinate in like 5 days. I was waiting for this shelf to arrive and man they shot up quick. Now I know what it means to have "leggy seedlings". Luckily I planted so many and some haven't germinate yet. So I can get rid of the leggy ones if I need to and just keep the good ones. We will see how they do.
This is the shelf, I am very satisfied for the money I spent.
Fits perfect in my little seed starting area in my laundry room.
As you can see, the ones that germinated early got leggy.
