Tent Growing

I have a 4x2x5 tall grow tent. I have a 150 watt sodium vapor light and two 200w equivelant cfl's that are both 2700K. My question is... Do you think I have enough light for my tent? It's 100% Mylar lined and I'm on day 20 of flowering and everything looks decent so far. Also, do you think the cfl's are even necessary or is the 150 HPS enough in my mylar tent? Thanks so much!

Yes it will work, keep the plants on the short side and use CFLs

More is better as long as you have adequate ventilation. Maybe try adding a small 100 watt mh? The plants would love it, the buds enjoy both 2700 and 6500 spectrums. Maybe a few 6500k cfls atleast? Could help add some extra bud weight in resin at the very least
