I would bury some stem from what I see when you up pot

I will do just that. I've never encountered this problem before. So thanks for the help.. I appreciate it

Afternoon squiggle.
It's great that you've got the light dialled in now, and you now know you can trust the meter readings.

Good afternoon mate.

Yeah, that's the word.. trust!! You just don't know until you test them out. It's like that infrared thermometer, it's actually 3 degrees out. It's junk really. But it's always 3 degrees out, so it's usable for now.. I never trust cheap gizmos.. how's the day going?

Yeah , trust is the right word. The thermometer being 3° out isn't that bad, but there's no way of calabrating them and you don't know how well it was done in the factory.
Here's the kicker though, how do you know it was 3° out, the device you used to confirm/check maybe 3° out and not the thermometer. ....then your head explodes....you need a calabrated correct device to check everything else.

Excuse the waffle I'm well stoned:D, the Victorians had the same problem when they got into having grand clocks around the house. The household would have a trusted time piece like an expensive pocket watch, and then set the other clocks around the house with that. The job usually fell to a trusted butler who wouldn't steal the watch.

My point (finally)
I'm trying to dial in my humidity, I've got three meters and they all show different humidity levels....then my head explodes..
Sorry again for stones waffle:rofl:
 
Waffle away:laugh:

Really good points, the thermometer I used to check the thermometer,could also be cheap junk and not calibrated either
.Kaboooom!!!! Me heads just exploded :laugh:

Love the history lesson :thumb:

How far out are the hygrometers you've got? Can you not take an average of all 3?
Apparently the analogue ones with a pointer work the best.. or buy a sooper doooper expensive digital one.

It's the same with the cheap PH pens. Even when you calibrate them at 7 with the Buffer solution. They are still out at lower and higher sides of the scale..

I think there is a saying that covers this. "You get what you pay for"

What you smoking on at the mo?
 
Lol. Yeah that's what i thought of doing an average of all 3, or a consensus if 2 are reading similar, but that just becomes a democracy by agreement, I could still be 20° off.
I agree with you, you get what you pay for. I'm going to get an ink bird humidity meter, I've got the temp one and it's the most accurate temperature device I've seen. It's the time piece that I set all other clocks(temp devices) with.
Cool, it's even fathers day coming up in UK now, I know what I'm asking for.
My fathers day gift list isn't like other dads. Lol.
 
The kids will be baffled by that request.
Dad! What's a hygrometer for?
Dad! Why do you need to measure humdidity?

So is inkbird the trusted name we can rely on. I haven't really looked into them..

Oh and 20 off is to risky.. I thought it was with in 1 or 2 .
Yup! Father's day has come just at the right time:cheesygrinsmiley:

Awesome.. you've got it at the sweet spot!! Nice!!!!!
 
Update thing!!!!

I've just noticed the pictures of the seedlings are quite deceptive. They look longer than they are.. the pots they are in are quite shallow. It's the same ones I've used for the last 3 grows.. (edit) no they aren't, according to the missus.

the tallest one is 98mm from soil to tip.. that's roughly 4 of them inch things for you guys who aren't metric.
Is that still classed as excessively leggy??

appreciate any reply.

thanks

Oh, we've already had that convo, I got grilled. I brought a pack of the small meters for the jars.
"What are they, what you gonna do with them"
I told him I'm going to attach a little humidity meter to each childs forehead in the house with a headband, as I'm concerned about your moisture levels and that's the sort of parent I am.
"Uugghh, you ain't putting that on my head" :rofl:

It's one that I trust, I've had my temp one seven years, extremely accurate, never let me down. I see them more and more on here in other people's grow rooms, oh I just see copperrein instal one.

Not much to report, the seedlings have stretched and gone all spindley, so I've dropped the light to 13 inches and got the Lux up to 3800.

just popped in for a look. i know you are playing with vpd charts and lux meters and the like...


13 inches is probably too close. even low power led can cause issues that close. led photons travel very up down directional and can displace leaf tissue as it passes through on a sub molecular level.

simple approach to running high power led with dimmers :

seedling - 24 - 36 inches above canopy at 50 - 65%
early veg - 24 - 36 inches above canopy at 60 - 75%
mid to late veg - 24 - 36 inches above canopy at 75 - 85%
flower - 18 - 24 inches above canopy at 90 - 100 %


i run my entire grow around 24 inches above canopy, and make use of the dimming function. it takes a bit to get used to. most mfgrs recommend running full up and adjusting for intensity with height, mostly due to the fact it can be difficult for growers to get used to the fixture.

the vpd charts and stuff are great for info and curiosity, but most times they just are a pretty picture showing what is impossible to achieve on a realistic budget. i wouldn't live by them, or stress about hitting those numbers.

Thank you popping up to have a look.
That is valuable information I can work with. This grow is going to be a learning curve for me as it's an all new environment and light.
Thanks for taking the time to explain this. It really is appreciated..
And I will do more research based on the Information you have given

Thanks again
 
if you've parked the light at 24 or 36 inches and you're still getting leggy seedlings the fix is simply dialing the light up another 5% or so until you get what you are looking for.

seedling and the seedling to veg stage is where most folk on led have an awkward time.
 
I was toying with that idea as it was originally set at 24 inches. But I was afraid of cooking them if i turned the power up. It took me a while to get the last LED light dialed in and that was only 100 watts.
It will all click into place eventually. Thank you for another piece of the jigsaw puzzle. It is of great help to me..

you're running in the neighbourhood of 400 - 450w, which is plenty for that space. you should be able to park the light at 24 inches and run the whole grow there once you get used to the light and dimmer.

a lot of folk start at the 36 inch mark, i find 24 to be easier once you've gotten the dimmer down. 36 is the recommended seedling height for fixtures with no dimming capability.

Seedlings Day 2
Day 7 from soaking seeds

Light: Sylstar GL-4000a
Medium: Store bought compost.
Pot size and type: to be confirmed
Grow space: 1metre X 1metre X 2metre
Strains: 1xSour diesel. 1xStar dawg. 1xBlueberry OG. All photoperiod and 1x White widow Auto

Water: Mineral, pH'd to 6.5


Howdy do folks, hope all is well with you lot..

Not much to report, the seedlings have stretched and gone all spindley, so I've dropped the light to 13 inches and got the Lux up to 3800.

I've also got a tiny usb fan blowing gently on them, they are barely moving but I'm hoping it will stop them stretching and it will focus the growth on strengthening them up.

If all that fails, I may put a pot extension, a sort of collar, a few inches deep and top it up with compost, burying the stem.. what's your thoughts on that?
Here's a few pictures of the leggy ladies

Anyway.. all thoughts, ideas and suggestions will be much appreciated.

Oh! @Grand Daddy Black . I'm wrong again. My tent is only 6 ft 6 not 8ft . I converted metric to Imperial wrong. So you are right ..

Thanks for stopping buy guys.
Looking forward to any input.

Take care,

Squiggle

Hey @Squiggle.

Good day to you my friend, hope all's well :thumb:

Mate, I'm having exactly the same issue with a couple of mine....Stretch armstrong going on.
I was hoping to get some advice on this as well. I have in the past buried the stem which seemed to work, I didn't seek advice on this at the time I just did it. I'm not sure about lowering the light as I don't have a Mr Lux at home right now. Problem is, this light Is bright, I only have it on 25% at the moment, when its up to 100% I need Marty Mcfly's Darth Vadar radiation suit on! :cool:
