Do you change bulbs for flowering?

yes. blue spectrum bulbs for growing, red spectrum bulbs for blooming/flowering.

I don't , it has more to do with the distance the light is from the top if the plant, the amount of light you provide the plants and the age and size of the plants. I us as white a light as I can and have great results!! Control the distance and you'll do great!

Generally yes, although i guess it depends what you are growing. Personally i switch to t5 bulbs that are between 30,000 k - 35,000 k. The lights it comes with are good for vegetative growth.

Yes you can. I have standard 60 watt bulbs in mine. They give off more mood lighting. They look great!

Yes you can replace the bulbs. You can see and feel a "coin" edge at the opening side of the lamp,just turn it counter clock wise and you can then take the bulbs out....David

You can switch the bulbs out on these lights, if you wish. I put small LED's in mine, and they worked perfectly.

These seem to be the standard bulbs for both growing and flowering because of it's wide spectrum. For inducing flowering even more a sodium halide lamp is specifically made for this. My plants had no problem flowering with this. My abutilon and jasmine won't stop flowering.

you could use HPS bulb for both veg & flower, but your plants will tend to stretch more during the veg phase. If you could, I would recommend using the mh for veg

I was not at all happy with the growth cycle of this bulb... The flowering stage is 12 hours on...it will produce nice fruit, but no size to them... So to answer your question, no and yes...it depends on your vegetables garden.

Mixing bulbs and ballasts is ALWAYS a bad idea. It's a fire hazard, plus it messes with your spectrum even if you do get it to work. There is no benefit, and your plants will suffer tremendously, if you don't burn the house down first. Apollo makes a 1000 watt version for a few bucks more if that's what you need.

As far as I could tell when I installed them, there isn't a way to change the bulb for the halo. Not easily, anyway.

No, the bulbs are not replaceable. When they burn out, you have to replace the whole thing.

No, not unless there is a way to do it that I have not figured out. Every time the lights come on they are in strobe mode, which I have found to be the only complaint I have with them.I will try to find the materials that came with the bulbs and If I learn differently, I will report back.

I would say no....you would have to unscrew the bottom plate to change the bulbs.

NO--this bulb does not put out nearly enough light to flower a "plant" and like mentioned by Dan, you need light in the 2500K-3000 range. Check the LUMENS of the bulb--you want 5000 lumens per sq ft for flowering plants.

You can select a 2700K bulb for this fixture when you check out. Although I haven't used this particular light for that purpose, I'm sure the 2700K bulb would do great for the growth and flowering stages.
