New Grower Northern Lights x10 + Big Bang 1x Auto Attic grow.

[shax]

Hello guys, I'm new here on this forum, but I've handled quiet a few grows before but im returning after 2 years into growing some Sensi NL auto and Greenhouse Big bang auto seed I got left (I lost it when I started with my grow but I wound it a week or so after other seeds spouted so I savted it for another grow)
The thing is that my attic is Triangular shaped. Its like 2m in height and 3 in weidth I think. It should do.
Im going to use soil and 400w hps with Scrog system.
So I wonder if you guys got any good ideas or suggestions for me? I mean my attic is truangular.
Seeds already sprouted and im going to put them in pots and make the growroom
or how should I call it tomorrow.

So are you going to frame out a space into the attic, or just paint everything white and use it as a grow room? What's your ventilation plan? Some attics get way hot in summer plus your HPS, so you may need to bring in cool air, and you'll need to plan for odor control as well.

GoAuto6 thank you for this warm welcome

AndyBotowin Thanks m8! Imagine attic in L shape, so i got that shorter part of L to work on. I mean to finih the isolation and make the walls of wooden plates. Yes the heat would be a big problem, but with isolation it should be managable, I will can still make it a room and use ventilation, or just send the hot air out throutgh roof and cool air from inside of house I guess.
Havent realy figured it out all yet. I'll give u some pics tomorrow when ill get my hands on it cheers

2 seeds have broken the grounds. other must still be doin idk what i guess... but they all should get out tomorrow, when i start the counting. I still havent gotten any pics but atleast i got a few ideas on the construction. Pics will come once i'm done. Is there any difference in veg stage if i got 12/12 or 24/0 or so... I was originaly planning to go 24/0 but im open to suggestions

When they're seedlings they can only use so much light, but as they grow bigger you should give them all you can. I run 18/6 from beginning to end along with a lot of other auto growers, but some go up to 24/0. There is some debate about whether autos benefit from a dark period each day, but I've seen plenty of great grows running 24/0. I just like to give my plants and my power bills a break. And in the heat of summer it's nice to be able to have a cooler dark period in the hottest hours of the afternoon.

Thanks for the advice so im going with 18/6 for now. 7 seeds came out today, hope i'll see the rest tomorrow Started the growroom thing on the attic and the project is gonna take me a few days i guess nvm that so far so good, babys looking strong!

UPDATE
day 3 90% germination atm only 1 seed didnt come out but i guess thats fine. 2nd set of leaves are showing up and they look like they like it on the attic, heat is no problem for now, i guess i got some time to isolate the whole attic before summer. I have them in yogurt pots atm but htgot one so i can see when roots make it throught, then they will be moved to final homes. I was thinking of 10l-15l pots, any suggestions on how big pots I should use ? cheers ppl

 

[AndyBotwin]

I'd say go with 15l if you have the space. That's around 4 gallons & 3-5 is the sweet spot for good yields with autos.

thanx i'll try to get close to that, since i got problems with height... not so bad but each cm is apreciated how far from plants should the light be since its 400w hps, now its like 30cm away from plants and seems to be good, they dont stretch. i just dont wanna risk putting it to close and burning them
high day to everyone^^
