First of all the question what do I need? is so vague, it depends what you want. Sounds to me like your in over your head with the medium/watering thing you have going... As you sound like a beginner you should have started with a good soil mix or soilless mix in pots, not perlite and reservoirs. No offence at all btw. At the beginning of your thread you mentioned twice that it was one hindu skunk plant, well just a few posts ago you referred to your plant"s" plural form, just curious. Also you can take that little data chip out of your digital camera, it plugs into your comp for quick uploads, that's what I did, I lost my cord too lol. Post some pics and people will have 10 times a better idea of how to help...if you want it or "them" to live right?
