Thank you for the replies. Very helpful. I will have to take it up with the distributor why they are advertising 1-14-0 product and shipping a 0-9-0 product. Sounds like the ole "bait and switch" to me.
Is anybody familiar with these Roots Organics Products from Aurora Innovations. I ordered a product called Super Phos Bat Guano. It said the NPK was 1-14-0. A distributor sent me a product called Super Phos Rock with NPK 0-9-0. This product says it is derived from Phosphate Rock, not bat...
Liquid Bone Meal - not sure if 100% organic - I don't care much for certification labels. Herculean Harvest is 0-6-0
GH pH down is phosphoric acid based - not organic - can only use citric acid to lower pH in organics IIRC
Since Certified Organic Cannabis is not a thing in my closet, I don't...
What I have been trying to learn up on is the reproductive process of the cannabis plant.
I guess they call cannabis fruit an achene. Each [what people incorrectly call] calyxes are actually bracts.
Each female flower has a single ovule, which is encapsulated by bracts.
Each female flower also...
I have the advantage as a new grower that I don't know any better. I experiment with everything. I foliar feed often. 3, sometimes 4 times a week. Its the third week of flower and I foliar sprayed back to back nights. Including the young nuglets; they get sprayed too. I hit them once with a...
AEA says chelated Calcium can be applied via foliar as a band-aid. Unchelated Calcium will not travel through the plant and should not be used as a foliar.
Many times Kempf says its important to have the calcium in the soil so it is uptaken though the roots. And for soil applications...

I saw Logan Lab M3 test results from 2 separate bags of FFOF and one of Happy Frog. Not sure it will help but I think the info is relevant to the discussion.
One bag of OF was 5.6pH, the other was 6.6, and Happy Frog was 6.3.
OF had total exchange capacities of 12.2 and 9.3 Means one had 33%...

Thank you pulse meter pro seems to give me exactly what I am looking for.
I use a doctor meter lux meter, not a par meter. I took PAR measurements off a YouTube channel review of my light and then measured in the same fashion with my lux meter. Lux or lumens or whatever divided by 60 gives me...
Let’s say I add some red. Or Blue. That’s not a quantifiable addition unless I know what I started with.
Thanks for the input, but am only looking for specific numbers, so I asked a specific question.
Only interested in B:G:R ratios for different K temp spectrums. Not interested in how to crop...
Just want to know exactly what is in the spectrum I’m giving them and how I would need to alter the number or type of led to tune the spectrum.
I might pick a different light that has a different mix of LEDs.
I’d like to be able to look at the specs and say ok, this light is 50% red, 20% blue...
My current lights have...
180 Samsung 3000K warm white LEDs
92 Samsung 5000K white LEDs
15 660nm deep red LEDs
1 730nm IR LED
Is still like to know how much Blue vs Green vs Red is in a 5000K and 3000K spectrum. I want to be able to say “I’m giving them 20% Blue (300-400nm) now but want to try...
So what I was looking for was integration of those curves. What Calculus?, I know... But calculus is what gives the answer.
To answer my question, you need to measure the area under those curves. How much area under the curve between 400 and 500nm, area under the curve from 500-600nm, and then...
I’ll try to raise them up but I don’t think it is light stress. I’m basing that off the fact that tops directly under a light show the same symptoms (as severe) as tops off in the corner of the tent. I would expect tops directly under a light (say 850 PPFD) to show worse symptoms than tops in...
