Simba - could you put in the first / second post what bulbs we want for regular old metal halide ballasts?

ICMag with help from Landrace Warden and The Vault is running a NEW contest in November! You can check it here. Prizes are seeds & forum premium access. Come join in!
Thank you so much Simba. Read almost the whole thread, and so glad I did. was about to purchase 1000 watt digi ballasts ("Greenhouse" brand), air cooled reflectors, a flip box, 1kw hortilux. Setting up a sealed room... But have always toyed w/ the idea of slamming a couple m/h in there, that's all I used to use m/h that is, like 20-really seriously-years ago. Anyways thanks again.

strainwhore,
There is no CMH available for "regular" old school M59,M58.......probe start halide ballasts. You need to use a pulse start metal halide ballast. Something like a m142, m140, m104 and a CMH that is made for pulse start operation or the bulbs that are 250w and 400w that most of us are using are retrofit bulbs that run on a standard HPS ballast of matching watttage.
Sorry Simba, I know the qeustion was for you, but I could not resist.

There have been a few discoveries and more than a few side roads taken during the thread. MPL and Simba have done a great job of keeping the front page updated by consolidating info in one spot.Hawk said:
I second the Cheers to MPL, Simba and Az.

That's what I thought after gleaning all the posts. Still, wanted it confirmed by those in the know. Thanks.
So to sum up for those that don't want to read all 107 pages:
Better Light Spectrum
Less Heat
HPS RETROFIT ONLY - unless your Metal Halide Ballast is PULSE START - which I assume most horticultural ballasts are not
Cheaper Bulbs
and the list goes on and on

FreezerBoy said:My girl laughed at me for supercropping. Topping just pissed her off and she grew even faster. Bending like a candy cane was the answer for me. As pics show, sativas remain highly flexible. Indicas may only allow you to bend over the very tip.
FreezerBoy,
Thanks for that suggestion. Did the best I could with most of the offenders. I'll get pics up. Much better than supercropping them over!!!!! Too thick in there.

Some CMH plants. The little ones are SweetBlue X JohnnyBlaze. The tall girl on the left is CanaBiogen Deluxe mix and smells like lemon, strong lemon!! The fat girl in the middle is a Reeferman "bonus mix" and is impressive even after being hammered with a 3-20-27 P/K bomb.
The last one is of some Reeferman "bonus mix" as well. Huge sqaure head and dense as hell, not sure yet on the smoke. Doesn't have the trich coverage of my JohnnyBlaze or the other bonus mix plant. It may still kick ass though, just drying now.

Simba, I think I already know what you're going to say, BUT, I dropped one of my ballasts when putting it in it's loaf pan home and now the sealant at the top of the igniter case has a SMALL but noticeble amount of movement (less than a mm). Is a 100% seal necessary for safe operation? I know it's a dumb question, but I am hoping that I can get out of having to buy an igniter.
Namaste, mess

APC + induction fan + CMH = no downtime
APC + induction fan + CMH = no downtime
I tried my computer back up power for my CMH light but found that it did not switch over in time to keep the arc going.
Recently I put my fan (67 watt Vent Axia) on same power output from my APC that my 100 watt HX ballast CMH is on (just a guess on ballast type, but it is magnetic). Now I can pull the wall plug and my CMH stays lit. It dims a little, but stays lit on battery backup. This is just a normal $100 600VA model. Might give me 15 minutes, but that would be great!
I believe the fan acts as a generator during the one second interim that it takes the APC to flick on. I would bet that as long as fan wattage is 60% of Ballast wattage then this will work. You also need a big enough APC. Big axial fans are the ticket. The ones that have so much momentum, they keep spinning down for 2 minutes after you unplug them: these such fans. Mine is an induction motor fan if that makes any difference.

mess,,
ya ur right id normally say get new..
but on the starter its not so bad.. its the cap we are more concerned about.. (allot smaller tolerance between layers in cap)
the starter should still be good.. go ahead and fire it up..
Bons,, ya.. i tried one of my apc today to find the same result.. i have to go look at the model number of hers.. to see why she has no delay..(she only has lights on that one)
im unsure why exactly the fan helps.. Hmm
also you can upgrade the battery to any size Lead Acid.. (i have a Elcheapo APC/UPS hooked to a Optima Yellow Top Ya i dont get more Juice for the Run time but i Get LONG Run Times..(its my Storm Backup System for Light, TV )
(match the kva to support lights etc then add extra battery to extend run time..
bons ya u could get a Pure Upconverter (or make one) run off a 12V optima having a Charge controller on it.. (on a timer) so it forces a drain off bat..
and a 1 farad cap.. but thinking u got a lil 100 watt unit..
honestly build the delay timer for 20 bucks and ur Golden..
light loss is not a Harm to plant like light leaks..

this is a MIGHTY impressive summary . i have a 150hps magnetic ballast (with no capacitor). will it run the 150CMH ?
chiliwalt said:
If I understand you correctly, you want to have one ballast hooked up to a relay hooked up to two lights, but you're only using one light until the power goes off, at which time the ballast would be switched over to the light that was originally not in use. If this is right, I don't see why not, but would it not be better to have two delay timers, an extra ballast, and just use both lights?
Am thinking the delay goes between the outlet and the ballast anyway...hmm...maybe using a power strip and putting the delay between the power strip and the outlet and plugging multiple ballasts into the strip?

250 and up is HPS ballasts and under that is pulse start MH ballasts.
