Hi, I am wanting to pull the trigger and buy this lighting system however I haven't been able to find many solid reviews on it. If anyone in the community owns one of these, could you please share your thoughts.
Hi-PAR S-One 315w CMH
Posted 22 April 2021 - 05:30 PM
It's been a while since I've looked at CMH, but the prices have dropped heaps since I last looked.
The light spectrum of CMH is impressive when compared to MH or HPS although I've never been a fan of some of the growth comparisons advertised because growth isn't just about light.
Personally I have an issue with anything listed as 'All-in-one', 'cos if one part dies, the whole thing dies. Having a separate ballast can benefit here.
I've got some older ballasts and I certainly wouldn't want to be suspending them above my plant. Early on I had my lighting rig collapse, if the ballasts had been up there too, ohh the damage would have been ugly. But I'd suspect those are all electronic/digital ballasts now so fairly light componentry now.
They are decent brand and there's a few 'reviews' I found which basically spew out the salesman line, but when you get past that sales crap. There are some decent reviews.
and it ain't by eating them.

Thanks for your reply merl1n. Many years ago I had a 400w HPS ballast/hood all in one and it seemed to be ok, never had any issues. I am keen to upgrade from HPS to CMH or Led to reduce heat/power bill and also get a better light spectrum. These Hi-Par products caught my attention a year or so ago but I couldn't justify upgrading at the time. I like the idea of having an all in one light system as I am wanting to try out the Blumat watering system with easy as organics growing medium this time around. With the blumats I will be having an external reservoir from the tent being gravity fed so I just wanted to minimize external components hence the all in one lighting system. Last night I came across this deal from Hyalite https://hyalite.com....-cmh-all-in-one I have never used a Hortitek product any thoughts on these?

can't comment on the hi par cmh , in the past they seemed to be coming out of china under different brand names , all the lights looked exactly the same
good luck with the blumats they are fantastic although they take a bit of dialing in , i would suggest getting the digital water meter as well & set the system based on the numbers
you get on the meter , 100 to 120 MBars in veg , 120 to 150 MBars in flower ( meter reading , lower the number higher the moisture level )
my thoughts on blumat set up , sorry if i'm telling you stuff you already know
when you transplant a seedling into it's final pot & water it in , push in the digital meter , over the coming days keep checking the meter , once it reads over 100 MBars , setup the
blumat carrots , leave them in the pot turned off for a couple hours to acclimate the carrots to the soil , then dial the carrots in
once you get well into flower , say about halfway through , you can dial the carrots back by very small increments over time , watch your meter & look to get the meter reading over 120 MBars
do this slowly
blumats don't like air , air in the lines or air around the carrots , buy a blumat tap or valve https://www.eurolux-...-shut-off-valve & add that to the end of the line
once the system is setup , b4 dialing the carrots in turn the tap on to run water through the system to remove any air in the lines , do the same if your reservoir ever runs dry , once refilled turn the
tap on to again remove any air
not as much of a prob but can be a prob is scoria ( aeration ) in the soil mix , stones around the carrots can create an air pocket causing the carrot to dry out a little quicker & water more frequently
only way to check that is to keep an eye on the carrots & watch for over watering , to fix this get some of the same soil , remove any aeration from the mix then remove the carrot from the soil , fill the
hole left by the carrot with the soil without aeration & push the carrot back into it's soil filled hole , this should solve the problem but again it's not a major problem to begin with , it's just something
to keep an eye on
hope that makes sense & sorry i can't help with the CMH choice
good luck with the great EAO soil mix & the use of blumats , both together should give you great results

this thread might help a bit with your choice ... carbcon gives a good summary of cmh systems:
thanks itchy ... that helps with my blumat setup mate.
i've been playing with the trophs for a few months now and still haven't found the sweet spot.

my first go with them wasn't so great but using the digital meter has definitely helped pug
i was getting over watering to begin with & kept dialing the carrots back which ultimately
completely dried out some of the carrots , results then were under watering plants causing yellowing
the meter will put you in the right range imho

yeah i understand that
so far i think you might have to let the top soil go a little drier than we'd like which has a few flow on effects
but i think we can live with that considering a couple of centimetres below the top is consistently moist letting the
soil dwellers thrive , imo if they are thriving nutrients & plant protection are less of an issue
in saying that the more we use the blumats the more we know & might think a little differently with more experience
