Hello I have some calcium powder on with d3 for my Nile monitor. Most everything alive requires these 2 minerals to function at their best. Would MJ plants benefit from it? D3 is typically taken in from direct sunlight. I don’t think these grow lights provide that. I looked into using grow lights for my Nile but decided not to be cause of the d3 requirements. Thoughts?
I’m pretty sure plants create their own vitamin D and calcium is usually supplied via one nutrient package or another. Organic grows usually get their calcium from something like Dolomite lime. Gypsum, or oyster shell and synthetic grows from calcium nitrate or similar.
