m0useanswered grow question a year ago it can do it, but it will not do it well. 78W total on compact florescent lighting is not ideal.
I grew some autos under 6 sunblaser LED strips at 18"/18w each. 108W total, it was descent. but better lights on the market for sure.
If its all you have go for it, but look into upgrading in the near future.
Good Luck!
