Hey how often is everyone changing out their lamps? I have been having really poor yields the last month or so. I chalked it up to cold weather
but im starting to have my doubts

i have a little over 4000 hours on the lamp.
which bulb/K do you have?

i read something on another forum (not sure which) that the 3K lasts longer than the 4k T12 and the 4K mogul based lasts the shortest.

Im using the Philips 3100k bulbs. everything i read before is these were supposed to last much longer the hps?

I guess i got almost a year out of the bulb so thats okay. i liked to switch HPS out every six months.

It is supposed to be closer to 2 years before degradation. But I have only had mine for months.

The 3100K in my Phantom is around a year old but hasn't shown any signs of slowing down yet. I'm also under the impression, like MMG stated above, that LEC bulbs are supposed to last for about 2 years.

Thanks for sharing that. I wonder when you will notice it needs replacement?

I changed them at 1 1/2 years and there was a bit of a difference in output once I threw the new bulb in.
I track my bulbs with a cheap 3 way meter with a light sensor. Not a irate by any means but clearly shows when they start to dim. And I always check because something seems a miss with the plants.

So I will eventually report back.

She was touchy during stretch and curled leaves under on her first feeding but that was weeks ago and she has blossomed into one pretty stunning girl.

The coloring has become much more dramatic and earlier under the cmh.

And my first try at the OG Kush x Trainwreck worked out real nice.

LOL, no competing brother, it's just nice to share info on new lights. I love testing the different light sources and seeing things first hand and learning more, the more rounded you are as a grower the better you become in my opinion. I'm still a newb but have learned a lot fast thanks mainly to this website and the people I have connected with through here. Glad to see this place back up and when I do the different journals it's just my way of trying to give back and pay it forward in respect and gratitude to those on here that have helped me in many different ways and continue to do so.

The one thing that is starting to become evident to me is that a good grower can just grow and doesn't stress over light source like a lot of people on here, you can grow no matter what, when things happen you adapt and push on, there's always "something".

Keep em green!
I suck growing 2 years still struggle to get a zip off a plant
