Ahhh, good to see you following along for the ride buddy.BTW, nice neckbeard, we can still see your second chin, you know.
No one has posted anything nasty in there hahaI saw someone post something nasty in your journal, I don't do that, that is low
Well hey at least I’m not ashamed to post my garden pictures ayyyyyes they did, it was removed, they said your plants looked liked shit.
I run an open hood DE 1000 watt bulb but I only have about 7' ceilings. It's almost too much for a taller grow on 1K so I do turn down that 1K bulb to lower wattages due to heat and/or intensity. The manufacturer of the bulb says its not good to turn down the wattages as it can throw off the spectrum and/or blow up the bulb but I've been doing it for 5-6 years. I also run a DE CMH 600 in the same hood but wouldn't dare go over 600W ballast setting. So far I haven't blown the 1K bulb, probably time to get a new one. I may look at 750 or 875 bulb.Right now I have just finished framing in walls for my veg and flower. I'm about to start getting into electrical work and can't decide on 1000w or 750w lamps. The price between the two units is negligible so that isn't a factor. I'm having trouble finding concrete info on the downsides to dimming your lamps. If there isn't really any downside to dimming the ballast I'd rather go with 1000w lights. My grow style may change. Maybe I decide to go to SOG somewhere down the line and have all this extra head space I'd be happy I had the stronger lights. So if a light is adjustable from 600w-1150w why would I buy 750w lamps? Thanks for any advice!
I have a dimmable DE from 750-1100 watts, I've used it in an 8ft tall shed and I've even used it in a 6.5ft grow tent. You just need to dim it accordingly.Right now I have just finished framing in walls for my veg and flower. I'm about to start getting into electrical work and can't decide on 1000w or 750w lamps.

So freaking strongJesus Christ.
I tried to find that light but the closest I found was this one:Check these out.
But last time I asked, they only sell them by lots of 40, for $32,000.
Surely they will sell them individually, or someone will come up with something just as good.
2650umol anyone???? They also sell different color temperatures. And are different umol, and wattage.
More light, less heat, better control
Philips GreenPower LED toplighting compact allows you to easily switch to LED lighting, replacing your existing HPS set-up, or building a new installation. The high light output of up to 2650 μmol/s or high efficacy of up to 3.6 μmol/J helps you effectively optimize crop growth, enhance crop quality and cut operational costs.
my 600w ballast will turn on at full power and then dim once the bulb its fully started up so I don't think running a lower wattage bulb in a higher ballast is a good ideaI'm located in the states. That's interesting. There's only a couple brands that I use and am very familiar with but have definitely seen a few more than that. I've never seen them adjustable by percentage.
I get you don't change the bulbs as you adjust/dim your ballast, but what I'm reading and understanding is you absolutely can. A 600w ballast will run a 600w bulb as intended. A 1000w digital ballast dialed to 600w will run a 600w bulb as intended. You don't ideally change bulbs often but if you found a great deal on 1000w digital ballasts with a setting for 600w and you ran your room with 600w bulbs there should be no difference running that vs 600w ballasts.
I have run 600 watt bulbs on 1000 watt ballasts set at 60%, done it a lot.my 600w ballast will turn on at full power and then dim once the bulb its fully started up so I don't think running a lower wattage bulb in a higher ballast is a good idea
Nearly 20 years ago I ran one of those big parabolic "umbrella" reflectors with a 1500 watt MH (stadium lighting). Thing was a fucking beast.View attachment 4718180
660w... the heat is radiated around the bulb like a doughnut, I'm not saying it's the best reflector ever (though it is imo) but in regards to close and light spread they can't be beat ime.
