Can I grow cauliflower indoors, from seed to harvest? Yes, you absolutely can. It may not grow quite as large as you might get outdoors, but it will still be decent size, and worth it!

Cauliflower scored a “B-“ on our “indoor-garden feasibility” scale, just like it’s cousin, broccoli. Cauliflower was actually fairly easy to grow in the indoor garden, despite warnings that it wouldn’t form heads at the warmer temperatures in my garden. However, like broccoli, it did take up a lot of space relative to the amount of food you get from one cauliflower plant. Plus, like broccoli, in an indoor environment, cauliflower took a long time from seed to harvest. Hence, the rather low score.
