For the last few years, I’ve been growing seedlings indoors each spring. I find it very enjoyable. Nothing beats those seasonal blues like the sign of green life in the face of a grey winter. I also enjoy bringing out my nurturing side to care for little plants that, hopefully, will produce fruit for my labor. Indoor seed starting has been a journey for me, with new lessons each year.
The first few times I tried growing seeds indoors was when I lived in a condo. Even though I didn’t have any land of my own, I was lucky to have tall ceilings, lots of windows, and a balcony. I started the seeds on a window ledge with some success and then moved them outside to pots. I assumed that a little bit of seed, soil, sun, and water would equal a healthy plant. I learned it wasn’t that simple. The type of soil, directness of light, growing space, and amount of water make a difference.After moving out of the condo and living temporarily with relatives, I tried starting seedlings using peat pots, again indoors. Then I moved them outside into the ground. That year, I also purchased some seedlings from a garden store. I observed that my seedlings didn’t do as well as the purchased ones. I asked myself: why didn’t my seedlings thrive, why did they become leggy, and why didn’t some tolerate being transplanted? With lots of questions, I read gardening books with more understanding.
Two years ago, I moved into our current house, which does not get much sunlight through the windows. The house came with a shop light in the basement, so I decided to grow seedlings under the florescent lights. Last year I set up a seed tray under the lights and had only a little success. Some seedlings I overwatered and lost. Others became leggy, discolored, or didn’t thrive when moved outdoors. I realized that the light bulbs were probably too old and didn’t give off enough light, I considered that more light bulbs were needed, and I realized the seedlings needed light for a longer time period. I acknowledged that the seedlings needed larger pots as they grew and that transplanting really was an important step. I questioned how many seedlings I should start indoors.
This year, I improved my system. I purchased three additional light fixtures, eight all new florescent bulbs, a seedling heat mat, and larger shelves, applying some new knowledge on what the plants needed. After getting the seeds to germinate with the heat mat, I set them on the shelves with each flat having two light fixtures over it. I set the light to be on for 16 hours and off for 8 hours. I set the heat mat to be on for 8 hours at night and off for 16 hours a day to promote stocky growth, per advice from from Mark of Voss Organics (told to the 2013 Permaculture Design Certificate class). When I also happen to be growing bean sprouts indoors, I water the seedlings with the water drained off from the sprouts to add some growth hormones. I’ve been watering the seedlings every morning with a small water bottle (a peri-bottle actually, if you know what that is), which works great to give each seedling a small amount of water. I transplanted the seedlings to larger pots when they were about two weeks old. My seedlings are doing better than previous years.However, I’m still learning. One challenge is how to keep all the seedlings close to the light. Some of the seedlings are short (peppers) and some seedlings are getting huge (nasturtium). I’ve been placing the tall seedlings on the right and the shorter ones on the left and angling the light fixtures. When seedlings are different heights, I need to be careful pulling out the flats to water them and then readjusting some of the leaves within the light fixtures so they’re not caught by the lights.
Another challenge is how to best label the seedlings. I want to keep track of the plant type, seed source, how old the plant is, and when it was transplanted and hardened off. Then I can see which care factors (light, temperature, water, growing medium, hardening off schedule) lead to the best seedlings. A piece of masking tape and a laundry marker are a start, but figuring out how to succinctly write down key information to identify the plant and track the plant’s milestones is an art. I’ve been labeling the plants with their plant type and a batch number and then tracking the plants on a spreadsheet.
A third challenge is doing a cost-benefit analysis of seed starting indoors. It’s one thing if I am doing the seed starting purely for enjoyment (where that would be the primary benefit), but if I had other things I preferred to do with my money and time, then would it be better to just purchase the seedlings that I wanted? I considered whether or not I would be saving money by starting my own seeds. My new setup was an investment in equipment and a commitment to the time it would take to raise the seedlings. After adding up the costs, I concluded that with a five year outlook, I would probably save about $100 per year by growing my own seedlings. To me, keeping costs down is an important secondary benefit.
The Journey Continues
Starting your own seeds is great fun. If you feel discouraged with limited resources, have hope that each year gets better with more trial and error. Sometimes I get to thinking that all the answers are in a book and that I can become good at something right away, but I always have to remind myself that experience teaches us a great deal. I’m sure I will have more challenges and successes to share as my journey continues.
