Scotty's 1st Grow

[Scotty 420]

Got a nice spread on your canopy, I think you'll have an excellent harvest coming!

Been looking more into that black domina as well, i think the strain popped up around 95/96, its a 4way indica. There are a few different 4way indicas out there that may be close or even the same just renamed. Piques my interest a bit too, I have intermittent stomach issues that as a man I refuse to address with a doctor visit

That one is on my future grow list too.

Yeah I found it at North Atlantic Seed Co. definitely going to run it next go round. The wife & I both have stomach issues so totally worth a try.

So today's the day I'm flipping to flower!! I just have a couple questions I thought I'd throw out there regarding how exactly to handle lighting. It's my understanding that I want to up the light intensity when I flip. Should I just turn up the dimmer switch & keep the lights at about the same height they've been (18") or should I raise the light a bit? Also do I just crank it up all at once or should I build up over a few days? Was planning or going from 60% to 90% seem reasonable? Thanks in advance for any advice.

Its hard to go by % on a dimmer. If going from 18/6 to 12/12 you want to increase intensity by 1/3 to compensate for the lower duration of light. I suggest doing that over a week or slightly more.

You dont need to be exact on numbers as they are only a guideline and you want to go by the plants but a guideline helps. Also helps to understand how DLI (daily light integral) works so a fast google search should help make that quick

If you can download this free app and give me the make and model of lights i can help give you some guidelines to get close then you just make small adjustments based on plant response to get dialed in.

If you aren't to 100% already I'd just slowly bring it up to that over a week or so period. Just a little each day and monitor their reaction. You got such a smooth grow going I'd just make that transition smooth as well. I messed around alot with upping my intensity and backing it back down...in hind sight should have taken it more easy, slow and steady wins the race here in my opinion.

I agree. It's much easier to figure out how high your light needs to be and at what intensity when you use DLI. I used this chart and the girls seemed to like it.

OK I have a couple different lux apps. The one I've found seems to be dead on to the manufacturers ppfd map is called "ppfd". It allows ppfd mapping. So I checked lux & the readings are going from 20-25k at 18" at 60%. Here's a par map I roughly made.

Lights are 2 vivosun VS1000's and 1 VS2000

600-900 is a good place to flower… im gonna say start watching once over 750-800 for light stress but id say you can likely bunp to 700ppfd pretty safely for now at flip and then let then grow into it depending on the stretch you may need to raise it.

The reason i like that other app is it’s usually fairly close but depends on the phone and then i convert it based on a more specific conversion based on the lights specs…

To give you an idea that app will read about 10x less than the actual ppfd of a blurple. I much prefer to do a more accurate conversion than a single calculation they use for all lights. Thats because lux is primarily the measurement of the green spectrum and the conversion is based of the amount of green in the spectrum to get a closer value of ppfd. This changes a lot depenong on the light you use

Per this chart it looks like I'm about where I need to be to start, maybe up by 10% every couple weeks until I hit 50k then start backing off

OK I'll go up 10% to 70 (I think that should get me to about 700 in the highest areas) & watch them, thanks!!

That's what happened with me. I started out at 25 DLI on flip and when I got to around 30 the plants pretty much just grew into the new DLI each week. Once I hit 40 I backed off gradually per the chart and they're now chilling at 32 DLI. Chop should be next week sometime!

@Aqua Man -Does the drop in DLI on flip do anything hormonally? Does it induce faster flower? Why drop PPFD on flip?

Yeah I actually couldn't download the app you linked it says it is designed for an older version of Android, which is kinda funny because my phone is far from cutting edge

I use Tent Buddy. Works pretty good. I have a Samsung Note 8 so my phone ain't no spring chicken.

No drop in ppfd just DLI. Thats because you have a shorter photoperiod so you up the intensity so they get the same or slightly more photons over the period of a day.

Photosynthetic rates are key. If you increase intensity then you increase the demand on the photosynthetic rates. At a certain point the plant cannot keep up and starts to go into photorespiration which reduces the photosynthetic efficiency. Thats how ppl came up with a 6 on 6 off light cycle because the plants are most efficient for the first 4-6 hrs of light. If you all want i can elaborate a lot on this but basically the higher the intensity the faster the head towards photorespiration as the plant wont be able to continue all processes at the sane rate so it has evolved to basically slow itself down and you can see this as light stress

 

[Rootsruler]

Maybe I didn't ask my question correctly? Why the drop in DLI right after flip when you're peaking the DLI in veg right before flip? Why not continue the intensity? What is the bio process that warrants this?

The drop in DLI is a result of the shorter photoperiod. The intensity is the same and you slowly increase that to bring the DLI back up.

DLI is a measurement of the amount of photons over the entire day… not to be confused with ppfd…. Completely different

I get that reducing the light period from 18/6 to 12/12 will shorten the DLI but why not increase PPFD so that the total DLI can remain the same? Is there a benefit to lowering then ramping up DLI in the flowering period?

You do it to allow the plants to adjust to the ppfd (intensity) with a higher demand for everything as you increase the ppfd , nutrients, transpiration etc…. If you just bang it up there the plants usually stress. Over a slower period they can adjust better. Remember that photosynthetic rates change with intensity not DLI if you went from 24/0 to 12/12 with the same DLI you would be asking the plant to immediately change its photosynthetic rates to double in a single day. Its an acclimation period

Just a quick update, 3 days into flower & stretching already seems to be starting. Went in last night & my temp/humidity sensor which is usually hanging an inch or 2 above the canopy was buried. Did a top dress with some dry amendments/compost tea & did a feed & water over the weekend. Looking good as far as I can tell, now I'm on the lookout for males, I actually wouldn't mind clearing out some room, lol.

Great job man

 

[Scotty 420]

1 week into flowering, everything still seems to be going pretty well. Definitely into the stretch now, tallest plants are 30" now. Starting to notice what I think are some pistils on a few of them, also have one showing what I think may be the beginning of male parts. It's the only one that seems to have these types of growth on them.

 

[MDK]

1 looks like a total male, no herm
2 looks like a total female, no herm hopefully!

Good eye and good clear pics. I think you are right on the male tho. Reg or fem seed for that one?

I'm kinda thinking...do you have a spot outside to put it? Get some pollen? I got like 4 or so different shits going outside we could make em have some babies? Just thinking...

Reg seed, I only had 2 fem seeds left, planted 6 regs hoping to end up with 5. I am OK with a couple males as the tent is packed & watering takes an age at this point lol.

Haha no I can't go outside with it, my yard is wide open & my wife would kill me if I put a huge plant out for the whole neighborhood to see.

 

[MDK]

We need a donor yard out of range lol. What strain does the male happen to be? If it's a male is there even any thc? I mean

Real talk idk how you did it but you lined up your grow perfect with the outdoor season...my biggest outdoor clone girls just threw pistols today. If there was a way to save your male...throwing it outside would almost be perfect continuance of its stage of flower. Pollen could probably be taken in like 3 weeks or a month.

I know it's something tasty too!

It's actually from a freebie tester pack, it's a cross of sour diesel & a strain called triangle market, don't know a lot about it. They do have some cool purple veining up the stems.

Dude I got an idea, I got a buddy in your area, I'll let ya know when he is at work and just go set it in his back yard...I almost had him convinced to be my keeper of males anyway hahaha this would just be his guiding light lmfao

Watch it be your neighbor or some shit

lol I don't have a problem dropping it off at someone's house as long as they know it's coming & are cool with it

 

[MDK]

It would almost be way funnier to me personally if he didn't know. Surprise! He'd call me first I know it!

He is a brother super cool

Man, don't risk your grow for me it's looking magnificent. I think you got a while before that male would do any harm mine were way later and I seem to be clear (knock on wood) of any pollen. I'd consider setting it outside the tent if possible if others share the same sentiment that it's 100% male. I've never seen it so early and so clearly but, the clarity makes it pretty clear in my opinion. I know tomorrow is Father's day (happy motherfuckers day to you by the way) so I could know earliest by tomorrow and maybe set that up for Monday if you decide it sounds cool.

Maybe that wide leaf would chop down some of the grow time on some of these more narrow leaf girls I got currently...I'm Loco man

Have a good one✌
