That's a difficult way to supplement calc. Crickets are not that great of a feeder either. I would just feed a commercial type bug food and dust with supplements. I use repashy calc plus every feeding, but you could mix a stand alone supps. I'm not sure what you have available, but something equal to a Canadian nightcrawler would be a superior feeder. Dubias are another really great alternative. As far as lights go they don't need any of that. Just a heat lamp to maintain 82f or so. I use a 40w red in a light with a dimmer.
