hi! i'm pretty new...we built our greenhouse in april. i'm doing raised beds and so far have been pretty successful. we've had some nights in the 20s here in knoxville, tn and the greenhouse hasn't gotten below 45 with just a portable radiator heater and a heat lamp, and it heats up nicely during the day. its connected to the house on two sides which helps...but the days are way shorter. i'm still getting tons of flowers on the tomatoes and peppers, but its taking forever for things to ripen up and things have slowed down some. i figure i need to supplement light. i have two 4' fluorescent lights out there right now that don't really do much and i'm looking at maybe getting a couple of t5 HO fixtures.

i'm looking at something like this: http://www.amazon.com/Light-6lamps-DL846S-Fluorescent-Hydrop...

or this: http://www.homedepot.com/p/ViaVolt-4-ft-4-Bulb-T5-High-Outpu...

i want the best light i can get at the lowest cost.

thoughts?
