Hi Mpetrizzle,

I'm not an expert and in the past I have mostly grown perennials and vegetables (tomato) in my basement green house, using a 1000 watt HPS to bring them to flower. There are a lot of good threads here about bringing plants to flower using only fluorescents (which, until now, I didn't think was a good idea). Good luck with your passiflora (they are so beautiful!) Please let us know if you have success.

Take care,
Luv_2_gardn
