garden, thank you very much for ur advise. i saw a 150w mercury vapor lamp at the hardware store for $27. should i get it? or get a 70w hps? but its more expensive. and also yes i will get the 42 watt cfl's in a few days. i was looking for a ph tester at wal mart but they didnt have any in the garden section. thanks for ur advice guys! ill post pics tomorrow evening.
