Wow Chuck, I don't even know who Doc is. I can tell you clearly don't know what's going on behind my melon. How do you figure that they are stretched out? Lol I don't claim to be an expert cultivator but I will say that you do not know what you're talking about. These Querkle when I took possession of them we're in a premature flower good friend of mine was shuffling rooms and well I guess you can imagine what happened. So this friend of mine was going to throw these girls away I adopted them for a small small price of 100 American banknotes. They were 4 ft tall and in 3.5 gallon and 5 gallon pots. I topped them all as I cut them around the 6th node from the bottom or the 6th node up.
Are you following me? I had to regress them and I put them in a 24hr veg. So prior to me adopting them they had been alive for about 6 weeks. I vegged them for 3 months before I flipped them last month. If you know anything about the Querkle phenotypes short and purple or big and sativa speedy. i have the second pheno.So between them getting topped and lollipop all the production is mid level and of course all the way up to the top so I don't understand why is it stretch to you because the top of those particular plants is higher than the plant but that's just doesn't make sense can you please explain to me your opinion of why my plants are stretched I'm very curious to hear your diatribe. There are 4 very distinct different Querkle in the room. So maybe I should put a couple more pictures up so that you can see the production and that is pretty much all big bud at the top Why you think that girls are stretched.? If i am wrong then please by all means correct me!...View attachment 3498135View attachment 3498136 View attachment 3498136 View attachment 3498139 View attachment 3498140
LOL, sorry DR.WHO said stringy, which is a better description of your plants
 
Plants don't look healthy at all to me. Leaves way too yellow. The plants in the middle left on that last pic look almost dead. Sorry to burst your bubble....

Are the 1000W bulbs CMH? Double ended? I ran the 400w phillips CMH for yrs but they stopped making them when they started the new line where you have to buy their ballast. So I went to the 1000w Solis Tek 4k MH. There is no doubt in my mind that white full spectrum light is better than the hps yellow.
They make ceramic discharge metal halide lamps that screw right into any mogul socket, as long as you're using a magnetic ballast. Philips Allstart CDM lamps. Google them. 330 watt and 860 watt, I believe. They are a direct replacement for the old 400 watt and 1000 watt MH lamps. The coolest part is that this "newer" technology utilizes the good ol' magnetic ballast.

This is incorrect. The 315w CMH uses a digital ballast. The old 400w CMH used mags but the newer ones use digis.

From my understanding it has to do with going from sine wave to square wave and that is where you get your efficiency and also longevity of lamp.

But I'm often misguided :-)

The only negatives I've heard for the curved sine wave was that it was harder for current digital ballast to produce a consistent wave at the higher frequencies they run. Do the new CMH's run at high or low frequency? If they run low frequency then I can't imagine there would be much of a difference in performance, but I don't know. And I was referring to the bulbs I mentioned, they require a magnetic ballast. I was unaware that the new 315's used the square wave. I would have to see the proven benefits of utilizing the square wave over curved before I shelled out that kinda money. Maybe there's already been studies down, idk?

The only benefit i see with a square wave over a sine/curved is the power supply could be over-driven at the same current input at the cost of ballast & maybe bulb reliability. It would explain the 315's power consumption vs the old ass 400's. Idk though, ive never got back into it.
Square waves are something that make me "eek" at work.

i'd have to look into it more to tell you for sure what frequency and all that, and i'm honestly too tired to do so right now. the only reason i felt the need to make the correction is because the bulbs you mentioned are the same ones i run, with mogul socket. i use them with the philips digital ballast. i hope i'm not coming off as a know-it-all, that isn't my intention. its just that these are the bulbs that i run and i KNOW that they require a digital ballast.

the older 400w ceramic metal halide could run off of the magnetic ballast, but the newer ones require the digital ballast.

i'm about to purchase two more of them so i'll be doing a bit more reading on them in the near future. hopefully in the process i'll educate myself a bit more as to how the tech works :dunce:

The Philips All Start bulbs require a mag ballast, says they are designed as a direct replacement for probe and pulse start magnetic ballast. I don't know if there are any negatives to using them with a digital ballast, but I guess you'll find out. I've heard the higher frequency will shorten bulb life?

@Sirbgreen Ignore the shit talkers, they're just jealous there little closet grow isn't this bad ass. Keep on growin dawg
I only have a closet grow, because that is all the room your mom would give me. and I'm jealous I can't kill leaves and grow an uneven canopy with stringy plants, LOL

makes total sense to grow a 9 ft plant and strip the bottom 3 ft of it. Effen genius

You must not be keeping her happy. So now we know you don't grow AND you don't know how to please a woman. Fucking faggot. Tough guy behind a keyboard over here guys, look out for this one. Seriously, if we were face to face you'd be swallowing some teeth. Pussy

@chuck estevez Who comes on here and shit talks someone else's grow? Who the fuck are you? I thought this was supposed to be a "community"? You add nothing positive to the thread, just agree with some other shit talker. Way to go dude

Hahaha that's where I got mine from!

I think I'm confused about product names. There's quite a few CDM/CMH bulbs etc and I'm obviously confused.

I only felt the need to "correct" you because I didn't want some body behind me to read it and use the wrong ballast. But now I see that they offer a version that can use the mag ballast, or one like I have, which uses the digital.

BTW, mine is low frequency, square wave.


Thanks for posting the link. And sorry for the confusion!
