I'm a newbie to product photography, trying to learn more as part of my job. We're doing a product photoshoot of plant collections inside a polytunnel (a bit like the example below).

Because of the translucent roof, the space is filled with a diffuse light.

Here is an example of the type of shots we are looking to do, as well as shots against a backdrop.

My question is: what lighting set up would you recommend to take the best photographs of these products given the uncontrollable light from the roof?

What I've tried / considered:

• Blocking out the ambient light with a dark box or moving to other space. Unfortunately the products aren't that mobile and are fairly large, so easier if we can shoot in situ as-is
• We have budget to invest in two softbox lights, backdrop and reflectors, so keen to know what best setup might be with these in combination with the camera

Thanks!
