Quantum yield (Φ) is defined as the ratio of the number of photons emitted to the number of photons absorbed.

Quantum yield variation across the three pathways of photosynthesis: not yet out of the dark - PubMed

The convergent quantum yield hypothesis (CQY) assumes that thermodynamics and natural selection jointly limit variation in the maximum energetic efficiency of photosynthesis in low light under otherwise specified conditions (e.g. temperature and CO(2) concentration). A literature survey of...

Frontiers | Substituting Far-Red for Traditionally Defined Photosynthetic Photons Results in Equal Canopy Quantum Yield for CO2 Fixation and Increased Photon Capture During Long-Term Studies: Implications for Re-Defining PAR

Far-red photons regulate shade avoidance responses and can have powerful effects on plant morphology and radiation capture. Recent studies have shown that fa...

thanks Dr.Bruce. More wondering about your engineering background.
 
yo! you would have an idea. where should i plant a begonia i got for a housewarming gift?

i was told "spackled sunlight -- NO afternoon sun exposure"

also, slow those plants down. you'll be going into flower before me if they keep their shit up.

Plant the begonia in a pot and leave it in the house for the winter, south facing window would be best. really doubt it would survive outside in your climate through winter. Put it outside next spring.

that's what i was thinking given its size. at this time of year, it doesn't have the time to establish enough of a rootzone to really have a "hold." the couple that gave it to us said they're hardy in our zone, and do best planted outside, but again -- timing.

i'll up-pot it and keep er indoors for this winter and pester you for placement in April :cool:
 
one great window in my house for sun exposure, I have 3x fluorescent lights above when it’s been cloudy or I want the blinds shut. Most of my houseplants go outside seasonally, but overwinter in the window, air just feels better in the house when you keep plants.
Most plants are rescues.

love that idea. the horticulturist that was here recommended some grow lights in strategic locations for some of my other plants that struggling, but i don't want the blaring grow affecting livability.

how you mounted yours is a great compromise! i might look into doing something similar. i've got a few already struggling and with the winter coming, more will become unhappy without enough photons.
 
like, look at your money tree plant. super happy. mine's been pissed since the cloudy days showed up. needs more light. could probably squeeze more vigor out of the spider plants and pathos with some carefully placed lighting too.

Look at the money tree plant? Look at that happy pooch!
 
Will do the topping this week, happy plants minus the calcium deposits on a few leaves. I know running tap water through humidifiers is not recommended, but it does the job. Plants transpiring enough now to hold the tent at 60rh.
Spiderfarmer sending a sf4000 to replace the broken se5000. Get to keep the 5000, and will have a look if it’s something I could repair, if only I lived closer to @Moe.Red😅

New light from spiderfarmer supposed to arrive Thursday, much needed to spread these plants out and give them room to breath. View attachment 25983

How are you gonna sex them, just flip them all? Or are you gonna take some cuts to preflower?
This is the stage with plants from seed that I usually get all stoked on the bigger plants that so often turn out to be male.
They're looking great as usual man.

that's why seed plants always grind my gears. especially regs. it's always the biggest, most vigorous ones that decide to grow nuts.

It’s true the biggest and best plants end up male sometimes. In this case the biggest pants in the room are all feminized, 8 fems 11 regs.
I plant to get all the fems I want to flower out into 3gal pots next transplant, was hoping some of the regs would show preflower in 1 gal, but I’ll probably have to flip to flower to find out, hoping to flip first week of November.

Now that's an interesting observation, forgot you had fems in there. Are the fems from a different breeder than the regs? Interesting that they are so much more robust. The bigguns are standouts in there.

3 of the fems are DFG. Garlic MacDragon,
5 x Do-Si-Do/Cookies fems. 00 seeds is the breeder.
 
Plants were way too cramped in the 4x4 and couldn’t wait for the new light to arrive on Thursday, I took my sf2000 out of storage, and spread the plants out, did a skirting and plucked what needed to go.
Took one of the larger plants and took a look at the roots, 1 week in the 1gal and already thick and circling the container. Plan to get the winners into 3gal fabric on Saturday. IMG_3793.jpeg

Yessir. They’re only getting 500ml once a day atm, but the big ones could use more, For sure ready for transplant.

what does your fertigation schedule look like during peak flower? do you mix large batches of nutrient solution to have on hand or have to mix multiple batches every watering when you're running through 12k+ ml every watering?
 
I have a 200litre fresh water res, and I fill and mix into 40litre res to water from, I use a pump and poly line with a shutoff to get water to the plants. Pretty fast.
Shop vac the runoff.
 
oooooh good lol i was having flashbacks to college, having to mix 10 one gallon jugs multiple times a day to keep all my ladies alive. My mind just pictured good ol OG toiling away, cursing the day he chose to grow his own lol

Hahahaha, I have considered automating the watering, but I like to get in there and make a game time decision. Takes less than 30min to do the watering and cleanup.

That's how the solo cups went, scooping the run off out.

been there dude...

in college, I cut two holes in the floor of the single wide trailer I was growing in. One had a tube running from the drain holes i cut in the kiddie pools i used as catch bins to under the trailer, the other had a massive blower fan pumping the heat out.

i couldn't do the scooping out anymore... not when i was dealing with gallons of runoff multiple times a day lol needless to say, i did NOT get my rental deposit back.

Yea neither did we for other reasons too lol.

And fuck that shit again indeed would go through 10+gallons hand mixing all, the bottom tent "cover/tray" collected it, was fine at first learning it all but now I'm ready to set up a platform to catch run off, maybe something similar to how you and dirtbag did it

dude, the platform is hella cheap to build. you could probably source all the parts for free, tbh. someone tears down an old shed, there's your sheeting. can probably salvage enough lumber to make the base, too. then, just need some sections of gutter and a container of some type.

I've set up a pump in my catch bin that kicks on when the irrigation pump does so i don't even have to move the catch bin anymore. have some 1/2" irrigation tubing running to a bucket outside the tent that i just empty when it's near full. soooo much easier but still too much work lol. need to plumb that shit outside so that it's a non-issue entirely. or, a floor drain would be nice.

good thought, my dad probably has some shit in his garage just laying around too, could probably just show him a picture and get something setup.

if i could build a room out, floor drains for sure that collect to a huge res to be re-amended/filtered
