True, by some logic I seem to think that the seed would be more attracted to the light but perhaps that's not the case. Yep! All of them, didn't push them down to far either. On a side note, I can't seem to get a grip on my grow tent. For over one hour it was at around 26-27C and when i...

Oh, you keep them in the dark untill they've sprouted? Interesting. Yes, all of them had taproots. I doubt I damaged the root when putting them into the rockwool, i've never been so careful with anything in my life :P but yes, it's a possibility but i used a pair of tweezers and didn't touch...

They are auto flowering so from my understanding, putting them från 18/6 to 12/12 won't change anything, they will flower after a few weeks regardless because of their genetics :) but i've changed it to 18/6, if anything, I might get a few g more due to the longer light period :)

Thank you, will probably start a diary threat once they sprout. But right now im at about 40 hours since I started germinating them, how long (ish) until they should form their first leaves do you think?

Alright but with the dome completely closed my RH is about 80-90% so that should help keep the rockwool moist as well. And yeah, I know that most people don't like start with rockwool, I couldn't get a hold of anything else where I live so if these succeed then at least i've made it through a...

So we're talking into the 90's??

Alright, I was aiming for the high 60's or perhaps 70's but i'm guessing it should be lowered from 80 to about 60 when they've sprouted leaves - right? Also is there a propper way to water rockwool, manually? Dipping it in water? Watering it from above (carefully of course)?

Yeah, I know that running at 400W MH maybe a bit overkill right now but I don't have any other solution sadly and they're not getting hit by any heat either so i'm trying to take the best precautions I can.

Wow, only 11 days? Im at day 3.5 so now i've got something to compare to when I hit day 11 ;) but looks good, nice colours and leaves!

Its a TT125UN, rated at 280m3/h at max rpm (4,6m3/min) My tent is 90x90x160cm which comes to about 1.3m3 I've calculated at about 20% loss, due to ducting but I still should be venting the tent at least every minute.

Yep! I've got it setup like this. Carbon filter - duct - cool tube (400W MH) - duct and then exhaust out. I've got no intake fan though, just relying on an opening which I open up when the light is on, since the pressure is negative (?) it should suck in air by itself if i'm not mistaken.

Why would 24 make any difference now before they've sprouted? Im just trying to understand since they wont be able to use the light im producing. It's just generating heat at a rate I need to get under control, so im just seeing that 12/12 or 18/6 would be more viable, so they have a "cool down"...

Yeah i'm sure :) Right now I'm just worried that they won't make it. The temperature is fluctuating, humidity is doing the same. Just need to get it straight how they should be treated in the stage after germination but before they've grown leaves.

We'll, they are germinated and they all have a taproot showing but none have made an apperance over the top layer of the rockwool. So in that regard, no. I'm just trying to get my temperature stable. Does humidity affect temperature, in a negative way? Since when i spray the inside of the tent...

Yeah, I see your point but like I said, I just read it and thought it made sense :) I'll adjust it to 18 when they've sprouted out of the rockwool. No need to adjust before that right? It won't really make them grow faster since they dont use the light.

Alright, I'll change it :) Read that it doesn't really make a difference with auto strains when it comes to 18/6 or 12/12.

Hello one and all! :) I've just started my first grow, I have 3 seeds that have been germinated and put into small cubes of rockwool (drained in 5.5 Ph water for about 1.5 hours before the seeds got planted). Up untill that stage all is great but here is where I can't find ANY information...
