I am flowering 12 plants, but am on a budget and am trying to save where I can right now. I am using 2 600 watt bulbs. One is a halide conversion and one is a sodium. Should I eat ramen and save some money to buy another sodium bulb, or am I ok running both a sodium and a halide during flowering?
From what I've heard, go the reverse osmosis route. It may be expensive, but it will make your water perfect. It's like bagels. The better the water, the better the bagel.
