Ortega pt II

@dankd I only turn my Spider Farmer farmer to 75%, max. Reviews said the same thing about my light, only turn it to 100% of you are supplementing with C02.

So what’s the negative to running par in excess of that? I’ve read the same stuff, but in practical application, I’ve failed to see the downside, other than visual tip burning of the leaves.
Honest question not sarcastic.

Honest question not sarcastic.

I have small 60x60 space, in that if I fire up 150W LED and If too close to the plants 20-25cm, the leafs go down like if the plant is overwatered.
Also I remember seening some bleached-white tips on the buds if too close.
Few cm makes a lot difference in that.

What I believe is the plant collects energy by day time, (like battery charging it needs tu fill energy capacity)
- outdoor is like low-medium-high-medium-low doses of sun energy (variable speed charging),
- indoor at full LED power, it is full amount all day long (so like leading to overcharging-overheating the battery)
- or indoor LED, power and distance corrected for exact plant energy capacity intput by the sunset (like turning of the charger exactly once battery is charged)

In other words, if too much power from LED is given to the plant, It could have enought energy after just 4 hours (from original 12) for example, then the light can be dimmed significantly, as plant dont need more.

Negative impact can be seen on plants behaviour with too high levels of light without CO2

I did try some suplement bag with Co2 for few weeks and it helped, I could have LED on full power and closer to the plant
(how closer I dont remember - WACO grow it was I believe)
It maybe helped a few grams in weight, but I dont need big harvests, so I dont use that no longer.

at the eight minute mark he talks about the veg and flower recommendations for regular and co2 added indoor grows. he said without added co2 the plant can't process more than 900 umols/m2/s (at 9:58 in the video)

although, a bugbee video explains with pictures how added co2 and higher par make bigger buds

i think you are talking about dli yes?

Besides wasting eletricity and $$ that the plant can't utilize the effects can become increasingly problematic. On the less severe end of the spectrum, one can experience exsessive foxtailing, lowered terps and cannabinoids, and airy unnapealling buds. On the worse end of the spectrum yields are affected, flowers can become "bleached" (especially when using LED) making the buds have zero effect, or stress the plant to the point it hermies or worse. I've heard of people figuratively frying their plants becuase they used so much exsessive power.

Very interesting topic and far more complicated imo.

Light are photons and this is energy.
When reaching the leaves surface it is the density or how many photons hit a certain area that is very important imo.
Secondly this concentration can be local on a smaller percentage of the plant or on a big part of the plant. That makes a big difference to me.
A well developped, big and healthy plant can cope with extra PPFD on a smaller part of its total leaf surface without seeing real negative effects (on the contrary, light stress can induce higher cannabinoid levels).
Smaller plants in hight are bound (due to their smaller size) to receive higher PPFD on the total leaf surface and this is where is becomes tricky.

I believe this is what Skuncle sees in his grows.

Next to that genetics and individuals play a rol also, some can just handle it better than others.

For me a good quality LED spectrum works very well also.

Working with a couple of different clones can teach a lot of how genetics, light, medium, environment all correlate with each other.
Trial and error has taught me well over the years.
Start prudent and slowly work yourself up is the best advice I can give to anybody and when in trouble post it here so to hear others opinions.

I see already lots of good info and first hand experience here from fellow members, nice!

A good thread to read up the basics and terms: https://mrnice.nl/forum/threads/shane-torpey-bruce-bugbee-phd-light-basics-par-dli-ppfd.18177/

Yup @Swifty , that is my experience, thinking and practice. Once we’ve all been doing this for 5+ years I think we all take some from books and take the rest from experience. When I was running grow tents, I focused a lot more on having an even top and had to be very careful with the light strength. Since I have more space I’m now looking for more penetration from the light. I run them around 1200 and that allows me about 3 foot of depth until power reaches 600 level. Certainly agree that a lot matters in what you’re growing, where you’re growing, and all the other environments. It’s always a great topic for conversation, because like most things I truly feel there’s not one answer and there’s many ways to achieve success.
Outdoor plants thrive under 2-3000 umol’s.
Personally, I blast them and watch how they handle it. I have blasted a few plants too much and that’s how I’ve learned. A light meter goes a long way and of course a dimmer of all lights. I appreciate all the feedback and I really enjoy it. Happy weekend.

check out this recent podcast with a guy who worked with nevil in the 80's who is actually canadian. talks about some of the og lines like nl5, early pearl and haze. seems to be knowledgeable of the real northern "lites" story (starts at 33 minutes)

Great podcast, Txs.
Not many 1st hand stories told nowadays over all the time that has past.

I caught myself being so intrigued by the stories that I would pause it and then go sample some of what they were talking about.
First, it was the NL5 and what I grew was nothing like the royalty they speak of. Though I did have a true sativa pheno, but it was missing the cannabinoids they speak of.
Then at the end I caught myself pausing again to sample my Neville’s Haze Mango, the closest I have to Neville‘s Haze, and damn I love this shit. Great daytime smoke in effect and taste. I have a pint sized jar left of NHM from September 2023 that is still moist when broken up
Next on my list is acquiring Neville’s Haze, one of the few MNS seeds I don’t have yet. Thanks for the motivation again, and as they said in the podcast, it’s always a compliment when the topic results in the desire to pop seeds and go pheno hunting.
