Welp....I'm in the same boat.
I bought 1 4 burner titan ng burner for flower room#1 and a 4 burner TrolMaster LP generator that I need to convert to ng. Neither have regulators which I need to buy. Since Trolmaster discontinued the co2 generators from their catalog, I'm searching for info on conversion from LP to NG. Are all conversion kits the same? (I haven't started looking yet)
Also was there a final thought on "Tee-ing" off a nat gas line into two lines, one into each room. (Dive of pipe etc). Are the flexible gas lines adequate or are the steal pipes a must? (I'm running LED's)
Thanks.
