2 Bags seeds, First Grow.

Out of 8 seeds i managed to get from some shitty male plant leaf. 2 have popped and the rest are dead/moulded.
I am growing in coco/perlite mix, have a 432W COB LED, a carbon filter, 6 inch outake fan, 3-1/2 inch intake fan in a 1.8mx1.8mx2m tent.
I have a few questions.
Firstly, how long after the first leaves are formed should i change the light to 12/12 or 16/8.
Also how close should i have my lights to the little babies.
And when should i started adding the A&B Coco nutrient mix.
Humidity is currently at about 45% and temp is around 26-28C.

Photo is today when it first popped through.

Leave it with 16-18 hrs of light. 12on-12off is only for flowering. And you won't get much while it's this young. I give mine at least a month under the long light hours before switching to shorter light cycle.

Hey Pichael

I am about two weeks ahead of you with similar set up but smaller grow space.

I gave mine 24hr for first few days then 18/6 now. Will keep with 18/6 for atleast another 3 weeks I think.

I have a 400w COB and found 2ft was too close, got some light stress, and upped it to 3ft. I am going to bring it down from there slowly.

I am growing in soil and only added root stimulator. I have only just given them their first bio grow veg nutes towards end of week two, at half strength.

I just uploaded my first thread if you want to check it out

Lets just say a previous tenant left most of it behind.

Yeah man for sure ill have a look and keep following so we can be growing and learning together, i presumed light stress is what is happening in the photo ive attached? Cause i made that assumption and raised the light sitting at about 3 1/2 feet. Also i dont current have an A/C unit to use for the room and the temp is measuring at 29.3C, im worried thats way too warm? Unfortunately in our area we are hitting at heatwave with 31C+ days where im located. Any ideas for that?

How close was your light before? Does your cob have reflective lens to concentrate light penetration more? 3.5ft might be too high so just watch for stretching over next few days and bring it closer 5-10cm at a time. Perhaps too early to tell if light stress, the feeder leaves look fine to me.

I think your temps are fine, on the upper end but not likely enough to stress the plant. Have your 6hr off period run from 11-17:00 or whatever the hottest part of the day is if not already.

Also a small fan circulating air in the room will help but don't blow directly on the seedling, oscillating against the wall perhaps.

The underside of the cotyledon looks bit yellow / brown, although could be from prior attached seed / casing, so should be OK if so.

Where I have no idea at all is on coco altho believe literally no nutritional value in this medium so you'll need to supplement that, like hydro, from the beginning, starting with very mild solution and reading your plant from there.

Are you planning to transplant to bigger pot?

Use T5 for the Veg. Easier on the seedlings and your electric bills,

The light was probably about atleast 1 1/2 foot lower than it is now.

The lights off time is 1000-1600 cause we also have solar so its better if it uses the power at night rather than during the day when its charging.

I have a floor box fan that has oscialation, ill probably just use that for the time being?

Yeah i wasnt sure when to start adding nutrients i know the coco has none but should i let it get a bit bigger befofe starting the nutes?

And yeah definitely planning on it, when is a good height to transfer, ill have the check the sizes i have.

I dont have any additional funds to be able to afford one at the moment.

Update: A newly found friend has given me three auto fem "ducksfeet" seeds. Currently in paper with two of them starting to poke out.
Keen to get them into their own pots soon.

So around 2ft initially too. Mine are doing good at 2.5ft now, down from 3ft.

I think you should start introducing mid strength nutes now, as it has nothing apart from its own initial germination energy to eat.

What's it in now, a plastic cup?? Assuming same rules as soil (altho I am not sure) you'll probably want to transplant when they root out the bottom of the cup and plant establishes itself a little, (2 nodes) which will likely be within 10-14 days max I'd imagine.

Good news on your autos, I have one at the moment. You'll want to start that in a bigger pot, (mines in 3 gallon) so not to have to transplant / shock it. Just maybe don't make same mistake I did in wetting all the medium since it will take a while to grow out the pot and could have some issues with pots not drying out (my problem). Maybe different for coco tho

How's your seedling coming along now man?

The original photo is still the only one thats come above ground still, only put the 3 auto fem seeds into soil yesterday. Starting on half strength nutes tomorrow when they need watering. If theres any visual updates ill upload some.

Have also switched the outake fan to a slightly more powerful 6 inch and switched the original 6 inch as the intake fan.

Still worrying about the temperatures, getting even higher, checked at 10 just before lights off and it was on 31.2C. Any thoughts?

Yeah those temps are getting too high. The bigger fan hasn't helped? Although if overall room temperature is high it won't, you need to cool the room.

If a/c unit is not option to put at / near the intake then you'll have to be creative with ice buckets or bottles near the pots but this is a tiring job.

How long this heat sticking around? It's winter where I am, my cupboard is near a door to my balcony so is helpful to keep temps in check and plenty fresh air.

I suspect in summer I'll have a bigger battle on my hands. I run my fan at half speed for silence, will probably need full speed when it gets hot and keep room as cool as possible.

You in a tent? Could leaving a panel open be an option for time being?

Its just those days where its over 30 outside that causes the house to heat up. Today was around the low 20s so it was a nice 26 in there. Also chosen at this point to only have half the COB LED panel turned on as it reduces heat and the amount of light being released is efficient.

And yeah in a tent, dont have different speed settings on my fans haha.

All 3 of the auto fems are now above ground, the first bag seed is going well too, no signs of life from the 2nd bag seed.

You do know Auto's should be started in the pot they will grow in? Transplanting is not advised.

Wasnt aware of this, will they be fine if i transplant them now or should i do it when theyve got a bit bigger?
In the photo ive attached is the length of the autos so far, i heard a little while back about the fact that they're chasing sun and they could end up drooping due to the weight of the leaves on the tiny stem? Anyone know anything there?

Now with one bag seed and 3 auto fems. The bag seed one is extremely short and im worried about it as its already up to its 3th pair of serrated leaves.

Tall and spindly means too far from light. Seedlings need good light and a breeze. Put the Auto's in final pots Now.

Hey Pichael

I did suggest you start your autos in bigger pots to prevent shock of transplant.

Autos will grow quicker as well than photo periods but looks like they're stretching a little.

You turned your cob down to half strength didn't you? So should be able to have these atleast 2ft maybe closer.

I wonder whether you're maybe keeping pots too saturated which is stunting photo growth, unless pics are post watering
