chuck,
I haven't hardened them off - yet. Our weather has been so April-like (minus and hard frosts) that the sunlight is not a factor. It's been above 70 very few times. The 17 I tansplanted already have seen maybe 1.5 days of sun and even then it was hardly warm (upper 50s-low 60s). Saturday is going to maybe be the first day that the sky is not overcast, but even then the temps will be in the low-mid 60s. Plus, they are on the back porch where they are shaded from the afternoon and evening sun. It doesn't look like it will get above 73 or so in the next five days, which means they will have at least eight days in the containers.
