Other than babies I apparently suck at growing things. I kind of take the approach of closing my eyes and hoping it all turns out. Unfortunately this approach is not really working when it comes to starting our garden from seeds. Last week I noticed that my seedlings weren't doing so great. Some were saggy while others were drying up. I tried watering from below (pour water into the bottom of the container) instead of misting from the top. I tried leaving the lids off the containers. I tried watering more and watering less. Finally I decided to head to twitter for advice. The best advice I was given was to try moving them to another room that had a bit less sun as the window I had them in was direct sunlight. I split my seedlings up into those that had fully sprouted and those that had just started or were being lazy and hadn't done anything at all. Those that had fully sprouted I moved to an upstairs bedroom window that still got sun but not as much as the kitchen window. I left the tops off and watered from the bottom every other day.  It took about 3 days to notice the difference. I was able to save most of them...but sadly not the herbs. They continued to weakly slump over in their containers.

My seeds aren't sprouting - Chances are the seeds were not placed in the container at the right depth.  Each seeds requires a different depth to be planted at. Another possible reason is that they have a longer germination period. My pepper plants were like this. They only just started to sprout!

I have mold on my containers - This is caused by excess moisture and lack of air movement. Just cut back a bit on the amount you are watering and leave the lids off the containers.

My seedlings are saggy - Once seeds have sprouted move them to indirect light and cut back on the watering. Obviously this is a bit part of where I went wrong but I caught it in time to fix it. 

I planted multiple seeds in one container and they all sprouted! - Lucky you! I am jealous of your obvious gardening genius. You have a few options. You can remove the weaker seedlings and let the strongest grow or you can attempt to split them up into separate containers.

I have no idea what is in each container anymore - I hear ya! I wrote on each toilet paper roll exactly what I was planting. But after weeks of watering I can barely read most of what I wrote. Luckily I am a really really anal good planner and I created little legends on top of each container. As I moved items around I updated the legend to keep me on track.

My seedlings are leaning in one direction - You need to turn your seedlings daily to ensure that they grow straight and each get equal amount of sunlight. If you don't do this they will lean in one direction and have poor stem growth.
