So sign a notarized declaration that all equipment you own is for growing weed and only growing weed. Cannareview would have a better idea then me but i don't think any of the lights and associated hard where say for marijuana production only anywhere on them. Lol I'd include a pic of the equipment you're claiming in action in your return.your growing expenses are only valid if you can not use that for another purpose. if you can use the lights for tomatoes, you can't claim them. it's a messed up thing in my opinion
