First time NL auto - Help needed!

[NLfanatic]

Hello fellow gardeners!
Long story short (kind of), it's my time to shine and grow my very first cannabis plant.

I chose NL auto fem by RQS because I've tried from a friend and I really liked it and because it has low odor during flowering and of course because it is rated as the best first-time-grower strain.

I'll make my own grow space from plywood and MDF.
Dimensions will be: 0.80m width, 0.54m depth and 1m height.
For non-metric users, it's 2,62 feet width, 1,77 feet depth and 3,28 feet height.

I will install a 12cm (4.72 inches) 95CFM fan as passive intake.

I also ordered 50 Full Spectrum LEDs of 3W each (actual 2.10) which will go into 12 x 150x20x5mm heatsinks (4 LEDs in each heatsink) with active cooling (40mm fan in each heatsink).
Each heatsink will be indepent and will rotate where I want it to.

Inside the grow box I will install a vertical fan on the left side for good air flow and behind the fan I will open 6 x 4cm (1,57 inches) holes for even distribution of air (as pictured below).



So far, I have everything figured out but my real problem is choosing soil and nutrients (oh and a proper filter).
I can't decide between composted or plain soil and provide the nutrients by hand.

My financials suck so I thought I'd go the cheap way and pick composted soil and just feed it deionized water.

A friend of mine provided the soil which is supposed to be good for any kind of plant.

Check the nutrients and other stuff and tell me if it's any good and if I'll need anything else except the soil (sorry for the image but it didn't have English language so I translated it).



Another concern is filtering the output air. I thought I could save a few bucks and just install a filter from my kitchen hood.
Would that make any difference? Because the box will be in my living room (unfortunately I live in a small house).

Any tips/info/suggestions is extremely appreciated and welcomed!
Thank you for your time reading all of this and sorry if my English is not so good!

first time i went with compost mixed with perlite and watered it filtered tap water.
and i dont think a kitchen fan would work? but im not sure. amazon has soler and palau inline fans for like 100CAD they work great.

I will use a 12cm fan (95 CFM) AND cotton filter like the ones that you use in a kitchen fan.
Unfortunately I am unemployed atm so I must go cheap until I get a job and make some money for a better system.

BUT based on my calculations, my fan is more than enough for the space (based on calculations, the grow space is 7,09 cubic feet and the fan can draw air from 95 cubic feet per minute).

I run my calculations again and you are right (unfortunately for me).
95 CFM is way too little as I'd need at least 140 CFM based on my grow space..
I don't know if the volume of objects inside the grow box matter for the total CFM calculations but still from 95 to 140 is a huge gap to cover..

I wonder If I could just use 2 exhaust fans of the same kind like the one I ordered and if it would still work as a passive intake.

 

[lotus710]

you could use two. i never had exhaust my first few time growing in my closet and it was fine. youll be good dawg.

i made a grow box with a power bar light sockets for plug ins and a cardboard box lmfaoXD it worked though

 

[lotus710]

delete

 

[NLfanatic]

The cardboard box was a thought but then I thought about moisture, mold and all of the sh1t that may harm my plant and it just ain't worth it.

It will be a shame to grow a good strain and have mold and other stuff in the buds that you don't want ending up in your buds -or worst- in your lungs.

I will install the first fan and see, I have more than enough time to order a second fan while my baby grows.

The only problem left is the nutrients and soil as I haven't configured everything yet and any help would be appreciated!

 

[lotus710]

i just used that paint for bathrooms n sht that prevents mold or whatever. your idea is better fosho. im doing a no till. get a bag of kelp meal from the feed store and some good vermicompost from craigs list or somewhere local and youll grow some good organic bud

 

[NLfanatic]

My problem is that I don't know what to ask when I get to the shop.
OK it's called vermicompost but how can I translate it to my language (Greek) to the clerk so he'll understand it? I'll probably figure it out though, do some Google Research etc.
What's a no till?

 

[lotus710]

no till is where you dont mess with the soil at all. you build a soil full good amendments add some worms mulch it and leave it for years and years and years and all you gotta do is chop down the plant and plant one right next to the stump and all the bugs and beneficials in the soil will break down the stump just like in nature. i suggest going here https://forum.grasscity.com/organic-growing/1299862-no-till-gardening.html and reading as much as you want and youll be great!

 

[NLfanatic]

Thanks for the info man. Wanted this info as I was thinking of making my own soil recipes!

 

[lotus710]

hell yeah dude! im down to help you out! im excited to watch you do this. also plant that auto directly in a 5 gallon pot with the soil no transplanting cant stress out autos

Much love
