Grow #2 - First ever tent attempt (say that after a few)!

[Greenjourneyman]

Make sure you give them a good water before you go,
happy holiday

 

[lenhug]

Just did, we're off!

 

[Captspaulding]

Be safe on your travels!

Thanks all, hope you all had a lovely Thanksgiving as well.

Right, back to these shenanigans.

So been having a 'mare trying to dial in the right temps and humidity but it's all a big learning process of course and to be expected.

In the garage (SoCal) so gets v cool overnight and humidity was also too low for seedlings. Both averaging around 50-55'/%. After some thought and various attempts at a solution I now have a warm mist humidifier sat just outside the intake flap being drawn in. This has greatly improved things. So now sitting around 64-75% humidity over 24hrs and temp is up to averaging 50' - 56'. Better but still not warm enough for them I think. I now have a heater coming today to place next to the humidifer and that, I'm hoping, should get us in the right zone.

I pity my poor seedlings with the wild environment changes they've been having to endure!

Speaking of which, a few pics from yesterday of them, v worried about the SMC, you'll see what I mean.

SMC

So what is going on here with the SMC? This may sound carzy but when I (stupidly) had my other (pre-chop) plants in here for the night I could have sworn I saw something fall from the GL and land on the SMC leaf, a tiny grub(?) or something which I wiped off but since then I'm seeing this get worse as in the pic. Eek! May be completely irrelevant but any thoughts, help or advice v much appreciated.

As mentioned above, I've been dialling in the tents temp/humidity so that has been a little wild to say the least for the last few days/week.

 

[Greenjourneyman]

Some nice growth. They look happy!not to worry right now about the small white splotches.
they survived you being away!

 

[lenhug]

Ha, thank you, that eases my worries somewhat. The newer leaves don't seem to have it so fingers crossed.

So I spoke too soon about the humidity and was still a little low (and swinging). After thinking about it a bit I realised the extractor fan on constantly was pulling and cycling whole tent too quickly. So I turned power level down as low as possible at first but still too much. Was like, howTF can I fix this? I had a brainwave along the lines of if only I could cycle when on/off with a timer, I wonder if it has...spies Cycle setting in setup.

That made a huge difference, fan now on cycle, 2m on/2m off. Humidity topping out in late 80% then dropping to to mid 50% each cycle (avg of 65%). Avg temp also sitting around 60'. Not quite perfect conditions but I think I need to stop over-thinking things and just let it go for a while now (bloody cold garage is to blame for all of this!), they are weeds after all! So easy and mesmerising to watch and tinker on the controller app though.

I've taken them outsides for some lovely Winter (hoho) sun for a few hours today as well and definitely some nice growth like you said. The Newberry Auto particularly is not hanging about:

All 20 days from germination.

Suppose my other qu is , am I ok with those humidity swings and just take the avg temp?

 

[lenhug]

Ok, so an update a week down the line. Day 27.

Switched over from 40% lights at around 2ft to 80% lights at 1.5ft (which I quickly pushed back up to 2ft after a day or so as felt too close) on Day 24 (29th Nov) for veg.

Still a little concerned about the the swings in temp/humidity but the avgs seem ok. But I am wondering whether to have the humidifier on at all (obvs easier without). Tried an experiment with it off, which option would be best here:

On (24hr avg)
Temp: 66' (swings between 57 - 70 as extractor fan does it work)
Humidity: 68% (swings between 55-80 as extractor fan does it work)

Off (24hr avg)
Temp: 58' (stay within a couple of degrees of this throughout)
Humidity: 56% (swings between 50 - 56 as extractor fan does it work)

That said, humidity has been high last few days so not sure those off values are representative. Usually down in the 30's (outside tent but ambient feeds in of course) which is definitely too low (and caused me drying problems on my first grow documented elsewhere - when I update it to today).

Or am I over worrying about all of this (highly likely)?


Anyway, let's break up this monotony and have some pics from this morning:

I am slightly concerned about the drooping leaves, anyone got any insights on that? Definitely not been overwatered so was maybe light stress when I turned them up and put them too close for 36hrs then changed height back? Or are they good as they are and I'm worrying over nothing at this point? I mean they look healthy to me.

And lastly I've also been taking them out for some delicious real(TM) sun as the weather is great here atm (SoCal) and next week is another mini heatwave. I feel like it does them lots of good and have absolutely nothing to back that up with!

Any and all comments, advice and thoughts welcome fellow green friends...



p.s. And yes @Greenjourneyman, I promise I will be burying them a bit more, maybe this weekend, or next before I leave.

Turn that light back down if you can. No need to change that output at all really until you want to make the flip. Heights good too!
My veg room runs at 45% at 3ft.

 

[lenhug]

Thank you, it is done. These are all autos though.

I am definitely being over-eager.

Auto or no,
Easy tiger!
how you doing buddy???

On e they hit a full on veg, and are comfortably into a full veg, you can start cranking it up incrementally. Seedling are mas sensitivo

 

[lenhug]

Yes that vague line between seedlings and veg states. How do you call it?

Once growth starts to become explosive. It depends on strain really though, but generally speaking, 21ish days after sprout they are comfortably in veg. Even for a fast flowing strain too. I generally won’t start nutrients until this time as well. That’s basically when plant demands start up.

Day 27 here!

 

[Greenjourneyman]

Looking nice dude.
you lucky you can still get some outdoor time. 24 degrees today out East.

[lenhug]

Any thoughts on the temp/humidity numbers I'm grappling with?

 

[Greenjourneyman]

Hey man,
as for temp and humidity. Temp just do your best. It’s winter here right, so when the space heater is on, every time I open the grow room door the whole places drops by a few degrees. Humidity is the hardest environmental factor to have consistent, as the plants themselves are continually changing the water vapor density around them. Over the course of the light dark cycle plants will transpire expelling vapor from leaf pores and stroma. Highest humidity happens with lights out. I would sweat it too too much, try experimenting with your exhaust fan on a timer and to run more frequently during times of high humidity.
be well and keep growing!
