many trees can actually be grown indoors, such as the juniper, provided they "HAVE WHAT THEY NEED". this consists of light, temp, humidity and nurishment. DONOT put a juniper in a window! this is the fastest way to kill it. the thermal dynamics near a widow can be VERY bad. The hot dry air from heaters is drawn across the surface of cold windows and as a result can dry and kill a junipers foliage. durring the summer, a window can act like a magnifying glass and fry your tree.

Your simple solution - get a 4 foot 2-bulb florecent strip, 6500k full sepectrom bulbs and a timer.this will produce 4200 lumen of light at about 2-6 inches fom the top of the trees. the juniper will still need to go dorment but you can grow several smaller trees this way. if you want more power go with T-5 florecent. A 4 foot 4-bulb fixture will produce 20,000 lumen of light at about 6-12 inches from the plants
