Switching bulbs

Hi I'm about switch to flowering mood.So I am switching my bulbs I'm using 4ft t5s should I change all of them to bloom bulbs or just do half ?

It won't hurt to have more of the light spectrum available to your plants. Ideally you should switch them all and have some supplemental lighting maybe some LEDs to cover the whole spectrum but not take away from the light your plants really need.

I would prefer to do half and half! Nothing better than a good mixed spectrum. Anyone who has ever used an HPS/MH hybrid bulb can testify to that! They take an HPS bulb casing and put both a 600 watt HPS and a 400 watt MH in a single 1000 watt casing. Makes for the best buds possible.

I prefer mixed spectrum T5's too. Closest you can get to the sun with artificial lighting is a mixed spectrum!

Yes I have 2 225 leds on the sides I think they help a lot since I placed them.

If you already have LEDs to supplement then I'd switch all of them. The LED will take care of the cooler side of the spectrum and you'll have more of the necessary light for flowering
