Nutrient issue is something I thought about but with the amount of food I've been giving I was leaning more towards a deficiency, I've been feeding with a bottled organic approach and have been feeding on the lighter side. I hope the near full strength feed I gave yesterday doesn't come back and bite me in the ass. Any knowledge on the dimming vs light height?

Knowledge, not really I guess. Personal preference I would raise a light or diffuse it before I dimmed it.

For instance, I just dropped a new seed. Tap root popped, so she's in her pot, in my veg tent under a 1kW hps, but thanks to my (patent pending) Glove Cup

, the light is diffused to 9k lux for her...100% success rate this way believe it or not...(so far..not tempting the gods here or anything...)

But no. Personally I wouldn't dim. This one will be getting 57k Lux in about 2 weeks anyways...

Very clever!

A view in one of my rooms. 315s with big hoods. The close up bud shot is from seed. It’s from my gorilla glue that I accidentally pollinated when I was looking for new strains, a couples males slid through.

How does she breath with the latex over her like that?

There are 2- 1"x3" openings I cut out on each side of the cup from bottom about 1/2 way up.

Here's the first properly dried bud I smoked today from that Skywalker OG btw. I do also have a 24w UVB light right next to the CMH for the sole purpose of trichome production.

SolarSystem® UVB

The latest generation high output UVB T5 fluorescent bulb. This system is perfect for a single light in a tent or several hundred lights in a large commercial operation.

(Heh. Just noticed they're sold out. Interesting...)

Needless to say, I'm happy with the results bongsmilie

was there a noticeable difference with the addition of the UVB?

I've never ran this strain before so unfortunately dont have a base to measure from.

Jakkar · Mar 8, 2020

gotcha, wasn’t sure there would be much benefit to run along side cmh considering how much the lights already produce.

I've heard mixed reviews on that. Some claim cmh=great uvb output. Some say it's quite minimal. I use the Phillips 3100k, so I figure I'm giving them the best shot possible.
Like I said though, seems like there's a lot of mixed reviews but very little DATA as far as cmh/uvb.

Its be nice if they'd fucking reclass the damn plant already so we can start getting real info/testing on growing instead of having to rely on "bro science"

Until then, I'm running both

How often do you guys change out your 315 bulbs?

I’ve been using the same bulbs for over a year now. They don’t seem to be slowing up. Using Phillips 3100k

gr865 · Mar 10, 2020

Phillips says their bulbs last 12,000 to 20,000 hours.
5 week veg and 10 week flower are about 1,700 hours.

My hort store guys says he sees most folks changing them after 4 or 5 grows.
My bulbs are on their 4th run and I plan on changing them next grow.

Little update on my 315 CMH and LED grow.

38 days since I flipped to 12/12

I am sure this has been ask before. I have run my 315's for 4 to 5 grows, not near the hours the lamp should last but my last grow the buds are kind of airy, not tight firm buds I am used too.
My hort shop guys says 4 to 5 grows is about right but what are you seeing?

Thanks for sharing. I've noticed my buds have been more on the airy side the past couple grows, I'm on about my 5th with my first go of cmh. I'm definitely ready for some new bulbs. Still nothing stacked up to the first run with the new bulbs, so I'm curious to see if the same happens when I buy new bulbs

Thinking back, well as much as this old mind can thank, and looking at pics of my past grows, the first two grows off the last new bulbs where very tight. Now that being said, the difference in overall weights and not been that different. This last grow of just under 23 zips of smokable buds, although thin, and about 8 zips of untrimmed buds, would have been to hard to trim, so that will go directly in making FECO.
My aver. on both my vertical and horizontal grow is about 25 zips, plus 6 zips of untrimmed buds. I don't weigh sugar leaf but I keep it to go into the FECO.

Sorry to interrupt your thread... I've been running two double ended Gavita lights in a 10' x 10' tent. The light intensity appears to be too much for the plants, so I have to keep them at 425 watts each. The lights go up to 825 watts. Does anyone have any suggestions for 315 watt cmh lights ? I'll be using a 4' x 8' tent in the future. The height is a measley 6 foot. Thank you for your time! bongsmilie

Everyone says different stuff. Can you get a pound off of a 315w cmh? I have alot of experience with hps. Im not worried about nutrient, genetics or any of that stuff. I've been growing 10 years. Im just worried about light coverage. In a 3x3 or 4x4 area will a cmh pull a pound easily or toughly.

Some girls right now under t5's getting mothered out. Just need to get lights for flowering now.
