We started our planning in February, I was putting seeds into potting mix not long after. I've been growing--335 seedlings to be exact--for 3 months and my body's telling me it's the middle of July.
H2 came over and took some great pics.
I barely have room in my seedling light rack to fit all the plants shown in the pictures above; an additional 160 seedlings have either been planted on one of our roofs or transferred to H2's rooftop greenhouse.
Coming up with a seed starting schedule that works off of our average last frost date and makes the most of our limited light rack space has been a challenge. It was a great learning experience; if you have the chance to do this with a few people you know, I'd encourage you to give it a shot.
