First time grower, how will it look when time to harvest? I have some pretty leaves on it now.

Check harvest time in the notes - like 6 weeks or whatever it says.

I am in San Jose, CA, Zone 9b. Is there any typo for the best seed sowing months for Pak Choy? The page says that Pak Choy prefers the temp 70-85 for growing. The best months for sowing seed are Nov/Dec/Jan. But the average temp is around 45-70 for these 3 months. Also there is high risk for the frost. The Pak Choy seed packages I had shows the best seed sowing months are Sept/Oct and Feb/March/April. is a wondaful website that I have been looking it for a long time, especially for the reminder. It will be even great if you can add some more Asian vegetable to your list, such as: Arugula / Tong Ho /Taiwan New Sword Leaf Lettuce / Yu Choi Sum / Gain Lan / Chinese Stem Lettuce / Xue-Li-Hong / Stem Mustard Zha Choy / Garlic Chives / RED STRIP Leaf Amaranth / Luffa / Green gourd / Spaghetti Squash / Winter melon / Hyacinth Bean / Long bean etc. I know a lot of Asian home gardeners in CA are looking for it. There are a lot vegetable planting information in the website now. But you are the one of them in the best list. Wish your online better and better.

Look up a chart for temperatures required to germinate vegetables. If your soil temperature is lower than what is required it will probably take longer to germinate or not germinate at all. Soil temp is different to air temp. A lot of the Asian greens would grow in the same climate zone and in similar seasons. Consideration has to be given to how hot it might be, how wet (storms etc) pests and diseases etc,
