Often this is insufficient depending upon the weather. I put together a simple system from purchased parts from Home Depot. A 23 Watt Compact Fluorescent Bulb daylight spectrum was used, a simple reflector, and a 23 liter plastic pail. The heat produced is minor and may be ignored. The lamp fixture was $20.00 complete. The Compact Fluorescent daylight spectrum bulbs were $20.00 for four. The pails was $3.00. I will add a small fan when one if found to move the air in the pail.
