600w hps or 400w + 250w???? Thoughts Please

I cant afford a 600w light at the moment but have a 400w and a 250w.

I'm flowering 1 K2, 1 Exodus Cheese and a pineapple gum with both the 400 and the 200.
I have a dr90 Secret Jardin Tent,am i going to see the same results as a 600w??

Heres some pics:

The one labelled Lemon Haze is actually K2. it was a present form a mate i thought it was lemon haze, i was told after that i got it wrong and its K2.

just wanna know if 650w is better than 600w???

if u can afford a 250 you can afford a 600

250's are about 120...140 with tax and shipping. This is $140...$155 with tax and shipping. Spend 15 more bux for 350 more watts. Who can beat that? And its dimmable, and its a mh/hps combo light.

oops, just now saw that you already have the 250...my bad. Well i guess for future reference then. You will be fine with the 400 and the 250. You will be running more amps than a 600 though.

Thank you hust wanted to know if the lumens are relativly close

I use 400 I worry about the heat output of the 600 I went the room but still think it might be too much for setup

Well ive been keeping temps down and my buds are visibly getting bigger by the day now im using both 400w and 250w. my electric is kinda high but im getting better results than ive every had.
My mate uses the same method as me by having two lights of different sizes u control ur light more and get closer to the plants than a 600w.

Max temps at the mo in the UK heat is 89 deg, averaging most days at 87 deg/40% humidity
