CFL for veg/clone cabinet. how many and how close.

ok i have a flower box going now and i'm setting up my clone/veg/mother box this weekend. i need to know how much light is TOO much light for freshly cut clones?

freshly cut clones in rockwool are going in a clone dome that is about 2 feet long and 1 foot deep and 8-10" tall can the CFLs be right above the dome part? i know clones don't need much light but i just want to know if this is too much.

say three 26w CFLs total to cover over the clone dome. too much?

then i'll have like 6 on the level above this one for after they root.

noone???????

2 lights will produce sufficient light for clones in an area that size, 1 light in a reflective area will create also produce enough light to sustain the clones during the first week-10 days
