Lighting is everything with pictures but taking pictures of Cannabis is very different for a few reasons. Many people cannot move there plants from out under there HID lighting and this makes it extremely hard to get a good spectrum if you canā??t go mobile with your plants then move the good lighting into the room just before lights on and work fast!

If you can set up a area it only takes about 4x4 and some cheap white cloth to make a box and then a few CFLā??s to shine either on the plant or bounce of the sheet according to desired effect. This one thing along with a back drop is why I take such great pictures.
Like growing weed the set up can be everything.

I think the canopy heat issue deserves discussing as I have seen a lot of heat related problems when people ask for my help. Heat can effect potency, taste, yield and also make you garden smell even worse as the buds cook under high temps.
Make sure you place a sensor at Canopy level so you know the ambient and radiant heat level.
