Get a globe bro. There cheap and will water your plants for you for a while. http://www.amazon.com/Aqua-Globes-Glass-Plant-Watering/dp/B0018KJWSW, just one of many.
Can I use this 400w HPS for Veg, and flowering? http://www.homedepot.com/buy/philips-400-watt-ed18-high-pressure-sodium-hid-light-bulb-140987.html
Sorry, this is my first grow, and learning experience.
The one I have is a 55w 2700k CFL. It's pretty damn big. Like 11 inches. But good advice! I'll be sure to pm you for any questions if you don't mind. Btw the case is about 14 inches wide, by 2 ft tall.
