okay i have 4 40 watt floros and a hydro set that grows 4 plants. the local hardware store has 150 watt hps lights. is that better than the floros. i wasn't happy with the buds on my last grows cause they were real fluffy. also, my floros are all cool white what kind of floros are best for flowering.
Go with the 150watt HPS! FOr Sure! It puts out more light than the flos/watt and also probably a lot easier to work with than 4 lights. ANd you should be using the warm flos for flowering because of there better "red" spectrum. And cool for Veg.
.....and tagging along with what he said Add the compact fluoros as side light to even increase your bud production More lumen ; more buds
