A good T5HO 2 bulb fixture would work and there are a couple LED
fixtures but I don't know their names. Hopefully someone more knowledgable about LED
's will chime in.
You are going to need root tabs for any crypts or swords as they are heavy root feeders. You will also need a fertilizer, something like Flourish Comprehensive and API Leaf Zone for potassium and iron would be a good combination but if your going heavily planted it would be better to get dry ferts and dose either El or PPS-Pro so you get a good macro and micro dosing regime. Also using a liquid carbon like Excel would help plants with growth and photosynthesis.
