How to SCROG when doing DWC

Let me start by saying I'm very new to this. I am about 2 weeks from harvest on my first successful grow. But I think my yield will be pretty small and I did have some issues along the way. I use 1x 1000 watt LED and one 3 gallon bucket for 1 plant. Swiss cheese auto. So I was wanting to try Scrog, but every week I switch out my buckets for fresh water and nutes. So my question is, how would you do scrog, and still be able to switch out the buckets every week.

I always used a small fish tank pump with a hose connected to it.Can leave it in there but it may get clogged with roots so best to just drop it in when doing water changes.

Thanks for the idea. I'll give that some thought.
