Seeds requiring light to germinate....

Do you mean seeds that shouldn't be covered with compost  when sowing?

Yes Veggie

I wanted to minimise the growlight space to seeds needing light to germinate as well as growing on germinated seeds.

Seeds (covered in compost) don't need Light to germinate - but seedlings need it to grow. However seeds may benefit from heat to germinate.
Unless your Growlight is heated, you may as well keep the space for seedlings and let your seeds germinate anywhere else you like.
