Hi!
Excellent thread you have here. It's a pleasure to see all of your babys/grows, setup and techniques.
I stumble upon your threads because of my interest in the cmh. Read all your previous thread (when you started using these lamps) and I'm trying to catch up with this one (still a bit to go ;)). Again excellent source of info, thank you for sharing.
I have a question regarding the CMH maybe you or someone else can clarify it for me.
I read that the Cmh run with a low frequency square wave ballast but most of the brands, on this side of the pond (Europe), are using a ultra high frequency ballast. Is it the same? Or better yet do they render the same output? Or is this ultra high frequency just a fancy way not to use the "diminishing" word low frequency on their products?
Thank you in advance (y)
Sweet smokes and green grows.

Ps-pardon my english but it's not my mother language. ;)
& btw this is my first post in this forum.

Hey thanks for popping in and the positive comments. Those 315w CMH bulbs do require the square wave ballasts to run at their peak efficiency. Most has/hid ballasts will not fire or burn the 315's so you need to be careful. Look for ballasts sold specifically to run the Philips 315w CMH and you'll be fine.

They're typically sold in kits with either a conversion kit (ballast, bulb & converter for a mogul socketed hood) or full kits including hood with appropriate socket for the bulbs, ballast, and sometimes bulb included.

Have a look here for available kits and see if you can find one locally:

Growershouse currently has a 15% off CMH sale, good time for discounts coming up to 4/20.

@Green_Elf there are two suitable ballast types for CMH/CDM/LEC type lamps;

The first is low frequency. Simple magnetic ballasts qualify, as they use line AC. The trouble is that they aren't a very efficient way to drive a lamp; if you take pics under their light, you'll notice dark bars. That's telling you the lamp is NOT running 30% of the time, due to the effect of the sine curve output.

The second type is digital- but not any digital will do. It also must be low frequency, else the lamp either won't strike at all or it will have very short life due to internal vibration. The best low frequency ballasts are 'square wave', which trade the sine curve output for one that looks like defenses on top of castle walls. This eliminates the period of low voltage and darkness, removing the dark stripes in your pics and boosting effective lamp output by 30%, while still using the same watts. Not surprisingly, these ballasts are more expensive but the added efficiency makes up for it.

I hope this helps. Sorry for the thread Jack, @GroErr !

got a second or third male? with a landrace i think there may be
some benefit to an openly pollinated orgy to preserve genetic diversity.

further filial generations could see the more subtle traits find expression
that would have otherwise been lost because they weren't expressed in
the original parents.

i was told about it by the folks at loud seeds, they called it the
"gangbang method", they use multiple males to pollinate a single
female and preserve some diversity instead of single parent inbreeding.

Interesting method and would make some good starter stock to breed from. With more space I'd try it but have to reserve some for flowers and other males, never enough room :( Only got one male, got down to 5 worthy plants with decent structure, smell, and colour and 4 were females. I was beginning to think they were fems!

Cheers Evil, buds are stacking up nicely, no complaints here :)

I stuck with the Canon line and got the T6i, pretty happy with it after having it a few months. I had an older T2i so was able to re-use some of the accessories I had including an extra 18-55mm lens which I take most of the macro shots with. If you're looking at DSLR's any of the Nikon and Canon's are nice cameras for taking garden pics, just go with whatever is in your budget you can't go wrong with them. Sometimes they bundle them with an extra lens and you can get a better deal that way, after market lenses can get expensive. But for basic shots in the garden the standard lens that comes with them is good. I got the IS lens in the Canon which has some nice features for stabilization. To get really good shots you need a tripod but I find with the IS series lens I don't need it

Of the two available lenses which do you recommend for our use? The 18-55 or the 18-135?

Also what makes the T6"i" worth twice as much as the T6? Sorry for the newb ???

I'd go with the 18-55 IS lens, it can take decent pics across a wide range of subjects and if you'll be mainly taking garden pics it's a decent macro lens in macro mode.

Main differences between the two models is 18 vs 24 megapixels and shutter speed is twice as fast on the T6i, that's what you pay for but either one would be fine for garden pics. I had the T2i until about 9 months ago or so and it was a dinosaur compared to the tech in these newer models. Still took decent pics, most of the pics in this thread were with the T2i. When I grabbed the T6i they had a deal with an extra zoom lens, 75-200mm for the same price as the standard kit with just the 18-55mm IS lens so I grabbed it up.

Ok thanks I will save for the T6i and just buy/cry once lol.

I like the built in wifi and what not. I appreciate the input.

Ahhh....theres the Panama girl you were talking about. Looks mostly sativa-ish?

How long do figure she might finish? And do you expect light, medium or heavy yield?

And if its the red hair pheno... and its anything like what was out here in the late 80s then youll have some spacey fun with that. A lot like the ROM i ran this season...
