Sandy, all you have to do is insert the bulbs and plug them in.

hi im using a 125w cfl envirolite 6400k do u thimk is enough to bloom cattleya and laelias?

Probably. Depends on the distance from the plant and if there is other light coming from outdoors. A 125watt light should yield approx 10,000 lux at 20-25cm from plant leaves. That's pretty close, but if the plant is exposed for at least 12-14 hours that might be enough. If possible, put the plant out in full sun for a couple hours between 10AM and noon or after 3PM. Also don't be afraid to put the plant out at night when temps cool down. Most Cats and Laelias respond to a cool down like this. I put my rupiculous Laelia out in full sun every time I can. I am looking for reddish purple leaves.

well the plants recive some light from outside too, they are all growing pretty well with plenty of roots and new shoots on all of them... some plants are just few cm from the bulb but consider that are all botanicals catteyas and laelias like c.velutina, scomb. thompsoniana and l. xanthyna and grandis and others ( some den) that require lot of light...
hope im going to see some blooms and not only new shoots...
