I’m running a MH 150watt in my 2.7x2.7…I have a phlizon 108watt blurple laying around…would running them together be any good or just stick to the MH…already looking for a upgrade for lights
How many plants?
The blurple is better than nothing. That 150 watt isn’t quite enough for that space. It will work just not ideal. So definitely use both till you can upgrade 
Both works for me.
I got two started but we will see…
