Love bugbees stuff.. was thinking about taking his online course last year but haven’t gotten to it yet.. have burned through all the free videos I can find multiple times. I know I’m pushing them pretty hard at these parameters but boy it has paid off and the size and quality is right up there.. I guess I was thinking that’s why if I slowed them down a bit they might recuperate better.. like letting them walk and catch their breath, but analogies only get you so far. I’ll keep pushing them and just see how they go.
Thanks for all the refs.

It sounds like we're birds of a feather re. Bugbee and et al.

"I know I’m pushing them pretty hard at these parameters but boy it has paid off and the size and quality is right up there." No doubt; and you're succeeding!

"I was thinking that’s why if I slowed them down a bit they might recuperate better.. like letting them walk and catch their breath, but analogies only get you so far. I’ll keep pushing them and just see how they go."
Fact based decision making. Works out pretty well, overall.

"Thanks for all the refs."
My pleasure — just spreading the "turn it up to 11" gospel.

1600 and 31C - life in the fast lane!

The PPFD is great but the temps give me pause. I've attached "the Chandra paper" for your light reading (no pun intended). At those temps, net photosynthesis is really rolling off, one, but, second, my thinking about temperature is that you're getting a lot of mass at those temps but THC content might be diminished.

From the paper:

Yeh, you're right at the peak - careful up there! :-)

That chart is helpful but it's important that the value that's plotted is "Net Photosynthesis" but we're not harvesting net photosynthesis. If you grind through the papers that I've attached, there's lots of evidence that more is better but the PPFD's that they're working with are lower than what you're using.

FWIW, in a few of his vids, Bugbee has stated that 1200 and 1200 are "optimal" but that was economic optimum. One phrase he used is that you can bump up your PPFD/DLI by 30% but yield only goes up by 15%.

Zheng and Westmoreland, who are coauthors on some of those papers, are former students of Bugbee, so it's one big, happy family.

Finally item - the site for this page is by the fellow who created HydroBuddy so he earned his chops in my book.

Chandra has mentioned in his papers that doubling the co2 - he was running his at 750ppm can increase yields up to 30% which is what I am doing running mine at 1500ppm.. which I believe let’s the productivity continue to upscale as the PPFD gets up to 1500par and over. I’m not particularly good with math or numbers but I have seen the end product over a number of runs and am happy with how things are going.. this run was shaping up to be something spectacular and would estimate hitting a 2.2g per watt yeild if not for the hiccup (last one was 2g pw)

I use a climate control system, and a split system AC, cO2 generator, humidity controller, par sensor, take regular readings of LST, chiller to keep res temp stable.. this light fuck up was such a rookie mistake.

I've been growing since '96. I just fucked up my light timers and unintentionally monster cropped costing me a few weeks LOL. We all do it LOL ouch ouch ouch.......

When you say just.. how long ago was this? Did you top the buds at all or just let them go?

As you can see they are growing into my light. 11/21 was when I discovered my fuck up (thanks @Laughing Grass )

They are slated to go here:

There's another foot and a half between them and the other Scorpion Diablo X here BUT I can't get my husband to lay off building modern art with my solventless unions etc... So maybe in another month it will be up. It wouldn't be the first grow I've scorched top colas off. I got so disgusted with the one growing through my light I took off it's tallest cola and it's just filling back in and ignoring me LOL I set myself back 4-6 weeks realistically and then I have to guard against mold because the cola on the Pink Sunsets are going to be large.

Not looking great.. has definitely switched back to flower but the bud structure is pretty crazy.. I doubt it will fill out, but I’m going to run it through to the end just to learn and see what happens.. and who knows, it could surprise me and fill out a bit yet.
How’s yours looking C2G?

Mine are slowly filling in. There are more and larger 'sugar' leaves, except these are the re-veg single leaves. But otherwise if I don't get mold from such large colas this should be a large harvest for me. A few pictures of Sherbinski's Pink Sunset
