So a couple weeks ago the 400W HID bulb that I use for my sun room plants burned out. I had already decided that I wanted to put a HID system in my crawlspace so I ordered a replacment bulb and a 1000W system. I decided I would swap out the 400W down to the crawlspace and replace it with the 1000W.
Everything arrived on Thursday and I spent the weekend putting it all together and stringing them up. Fired up the 400W in the crawlspace on Sunday and was very happy about it because I now have ~4-6 time the growing area I had before.
Last night I finished setting up the 1000W in the sunroom.
OH DEAR LORD!!! It is so friggin bright that I quite seriously need to wear sunglasses while working on the plants under it. I am also noticing that the plants probably could have used a new light sooner because under the 1000W system they look a little lackluster. Guess the 3 year old 400W bulb had lost a bit of its "umph" with time.
