Help on light setup in room.

If you have a mylar tent setup where everything is reflective and I have a 600 watt HPS bulb in there, is it ok if two plants that are in there 8th week are sort of in the corner not under the light and have grown slightly above the light? Will they still get enough light because of the reflection? Or do I have to switch things up?

U really oughtta keep rotatin em when they're crammed in there like it sounds they are. They will get light from the reflection, but depending on how far into flowering u are, u may wanna bend them tops down so they'll fit so u get the best nugs out of them.

tie a string to the top of the plant, pop a hole in the top of the pot to pull the string through and pull her down. Even this late in flower it's probably flexible enough to bend over in one pull. If it seems too stiff bend half way one day, it'll loosed up overnight and the rest of the way the next day.
Should end up with nearly half the height and bend it to whatever works best in your space.

... ... if ur stems are too hard and brittle u can also pinch the stem where u want it to bend to soften it up then go from there...

I was able to bend the whole plant down enough so I can have the majority under the light, it's about 6-8 inches away from the light, which has a glass cover on it, do you think it's ok like that?

Long as it isn't gettin fried by the light then its fine and dandy. If not, however.... ....
