XR15 Pro or Hydra

[Sean_Jacob228]

Picked up a pair of pretty much new XR15 G5. Currently on my 90G which is 48” L 24”D I have a hydra 64 with a prime 16 on each side. Just curious as to if I should switch to them or stick to AI. Thanks in advance

I would see the PAR readings of both and go with the one that gives you the best coverage

Two XR15's would be similar to running two AI32's. In my opinion, you've got more power and flexibility with the AI64 and 2 x Primes.

I agree with @Gumbies R Us though: buy or borrow a PAR meter and do an A-B test of the two different setups.
