Upgrade to 5x5?

I currently have a 4x4 with a 600w HPS light. I was thinking about upgrading to a 5x5 with 1000w HPS. I currently do not have room for both. Would it be worth it to upgrade?

You will be gaining 9 square feet of grow space. So if you have the room and need then upgrade.

A 5x5 is actually a decent upgrade a foot on each side all around depends how much bud you want 1000 watts is perfect for 5x5 i have a 4x4 running 750 watts on a dimmer pull about a pound a cycle and have seen 5x5 pull one and a half its a decent difference as long as were talking hpsodium
