Need advice about harvest

Hello. I live in the country but still have neighbors. I have 3 plants in my backyard that have been bent over and trained down and they are doing great but not quite ready to harvest. I noticed today that someone besides me has been out there and cut a few buds off... anyway.... i am paranoid now and want to bring them inside asap before they get stolen. I Have a 600 hps light that already has plants under it and a 400 metal halide that I could put the outside plants under. I know that the 600 would be better but will they still finish up if I put them under the 400 metal halide? Any advice would be appreciated. Thanks!!

They will definetly finish up but of course the more light nicer, tighter bigger buds...

why not stick em all under both lights?

This may sound crazy but did you look on the ground around the plants for any sign of the buds? If you're lucky the "thief" was a rabbit, those little bastards have sharp teeth and when you see the cut you'll swear it was a pruning shear that did it. They don't smoke it or even eat it, they just bite buds off and leave them there. My thinking is that if someone had come in your yard they'd have snatched the whole plant(s). I had to move all of my plants indoors this year, but I'll tell about it in a thread of my own.

Bringing them in if you can seems like a good idea. Depending on where you live you might get just as much, if not more light from your 600hps than you're getting outside this time of year anyway.

Thanks alot you guys for the info.
I was able to move some stuff around and fit them under the 600 hps light and they are doing fine. I propped one of them up on a ladder.
