Glass does block some light. Iirc 5% from my readings.
But 5% is nothing in my book. I KILL it with cmh. I'll never go back to hps or mh. EVER
Thanks @DemonTrich. I had gotten discouraged because everyone claimed that basically no UV B will make it through the glass and because I have the GE it has to be in an enclosed fixture. It doesn't have the spool that holds the arc tube in place in case it explodes. I am a plumber and I will be installing sprinkler heads in my grow area.
Last question sorry...does this affect calyx to leaf ratio as much as everyone claims? People swear the cmh grows more leaf than Hps.
Uvb.... not changing anything else in the garden. .. grow one plant with and one plant without ultraviolet B.... youll see the magic bullet at work.There is no magic bullet to increase resin or potency. Any product that claims otherwise is total bullshit. Potency and resin are determined by three things in this order:
Genetics
Plant health
Drying, curing and processing technique
Keep in mind that visible crystal also has zero relation to potency as well. Trust your mental palette, not your eyes.
I dont believe in that vpd shit at all.....if you have ever grown in high desert or desert Conditions. .. your whole grow will be in the red on that chart. Stoma adapt to climate.If you are running GH then maybe some Florolicious Plus, it seemed to boost flavor at least.
I too am really liking the 315s. I am getting purplish hues where I never did before using 600s. The trich production does seem better too
And what a nice light to work under. A nice white light instead of the yellow that makes identifying pests and plant health much easier.
I also can vouch for the lower humidity levels helping with trichs. I live in a cool, dry area and my VPD is always jacked up. Without running a fogger 24/7 I can only get my rh to swing between 40 and 60 percent, but I keep the temps in the mid 70s and never worry about mold.
I do deal with some heat / vpd issues but the buds are usually pretty friggin frosty!
I wish I could post my last harvest pics. Still getting that error code.
I've tried to upload them on about 10 threads. No luck. Even went into my phone, edited them, still no go.
what is your foot print that you are using for 315's ...Quality genetics 1st and foremost
I use cmh bulbs. Absolutely LOVE these lights. It's the 600hps and mh KILLER!
Terpinator
This stuff works on all 16 strains I run.
Very well put....and I can't stress this ENOUGH....GENETICS GENETICS GENETICS!! Of course the drying/curing is the second most important thing ( being that you know what you're doing during the grow, and have a nice, healthy, MATURE, lady). You could have the finest genetics, awesome grow, and totally f**k it up with your drying/ curing method...There is no magic bullet to increase resin or potency. Any product that claims otherwise is total bullshit. Potency and resin are determined by three things in this order:
