The cmh’s put out some good uvb...i was under the impression that uvb, done well, increases trichs somehow, but my bud @Randomblame , who i consider an expert grower and light guy, told me that research shows uvb increases the % of thc in the trichs not their number and/or size, nor does it seem to affect the amount of terps.
Personally, i have no complaints about the frostiness or potency of my plants.
Except for possibly triggering Cannabinoid Hypermesis Syndrome, i’m all for anything that pumps up thc without neg side effects....

He does great with CMH - but uses a lot of watts to do it! I'm all about efficiency myself.

Me too. I have a buddy running 2k Watts of HPS over his 4 plants. He was able to get a pound each last grow but his ratio of grams per watt was way lower than mine at a total of 1200 watts, just 300 over each plant. He's not sold on my QBs yet. When I do a pound per as he did, I think he'll listen up.

Do you put anything in your res besides just nutes?
Like h202, orca or drip clean?

Nope, CMH has only some UVA but no UVB. But UVA can have such effects cause it has the same signaling effects like blue light for instance denser growth, higher chlorophyll density, smaller leaves and a higher trichome density too. It also changes the terpene profile(smell) and it causes a slightly higher potency.
I've seen a test HPS vs CMH vs 3k LED and CMH ended with 1,5% higher thc values, HPS with 0,6% more. BUT...
LED outperformed both HPS and CMH easily in terms of yield and in the end the LED side ended up with the highest amount of trichomes/thc just because of much more yield.
So instead of considering using a DE CMH I would rather add more LED and 1 or 2 reptile bulbs. You can profit from LED yields and from UVA as well as from UVB and you get even more thc because UVB has a much stronger effect. (up to 30% increase in the best case)
These bulbs also add some blue and purple light in the 410 and 440nm range(causing higher chlorophyll density and all that mentioned above). Those dark blue and purple wavelength have a huge effect on the color expression of the plants and you will see probably the most colorful plants you have ever seen when usind such bulbs in the flowering stage.
With my last grow I had 5 different sativa girls in my little cab and the Amnesia x Bluedream cross started to show nice pinkish looking pistels around week 5. I first thought, damned, its a bit too early and inspected them under 'normal' light but none of them were brown or wilted.
They have only changed their color and I've never seen that before and f**k, that means something!

I know you're asking OG... But I use Garden Friendly Fungicide and Flying Skull Z7... for reg DWC the flying skull probably ins't necessary but its very nice to have in RDWC

Same microbe as hydroguard, cept a gazillion times more concentrated, and less expensive..
I put 1mL per gallon of water, after nutes and pH’ing, when i fill; a mL anytime i add new water (after pH’ing)...i’m more concerned about underdoing it than overdoing it....

Thanks for correcting me RB....so, i just wanna be certain: i know from you, blue and uva increase thc and other cannabinoid contents, and i’ve read they increase terps as well. Sounds like they also increase quantity of trichs: correct or incorrect? And uvb, increases trichs or not, thought you mentioned not in an earlier convo?

You get a higher trichome density when plants receive more blue to UVA wavelengths but thats more because all inside the plant is more densely packed and leaves and flowers will stay all a little smaller. But more like 10-12% blue total has a lowering effect on yield. If 5k would yield the same like 3k we would probably all use 5k.
So you get not really more trichomes bud the trichomes density per cm² have increased and that causes the slightly higher potency. A changed terpene profile has also an effect on the high you get and a plant grown with UVA/B can smell and taste different and also cause a different stoned.
UVB on the other hand increases the thc content in the resin itself. So either the trichomes get a few percent bigger or there is just a higher concentration in the liquid resin. Really hard to say that ..

I use to use total ponds barley extract for my enzyme.
I’ve been using only drip clean, aside from normal nutes, so far this grow. I haven’t changed either of my reservoirs yet. Just been mixing and topping off. Been wondering if I should add something to help the res. But everything seems to be doing good so far. Been worried cause my res temps start to get a little too high. Turned my a/c down some more so hopefully that’ll help keep it down.

I wouldn’t go w/out hydroguard or gff...but if you choose to do so, imo, make sure your bubbles are strong, your water temp is 68-72, and pH is 6.0-6.1.
At first sign of droopy leaves, stinky res, or brown slimy areas on roots...i’d call the dwc emergency room...

I’ll get myself some of that gff
Thanks for the info and tip. Rather be safe than sorry.

Still can get a mess, but you are putting yourself on the likely winning track..,.
Can’t wait to see what you’re up to.

Wayyyy more cost-effective than hydroguard.
Putting 1ml of GFF into 1.5gal water makes hydroguard. (Like what comes in the hydroguard bottle).
I agree with OG that it's hard to go overkill with it, but that said I run 1ml per 4gals in my res and it works great.
On the total ponds stuff -- the pond clarifier? Or something else? Z7 *is* pricy so if that stuff would accomplish the same goal I'd be interested in trying it.
