Noob want to grow marijuana

Hello, i'm very interested to plant my own marijuana but since i'm a noob at it i will tell you what i'm planing to do and then please comment on that.


I want to plant Big Bud because it has the bigest yield so are these information correct?
Big Bud - Yield(up to 800g), Height (100-140cm);

I will build a closet that is 50cm x 40cm x 150cm(height), but it the size may be changed. 50cm depth will stay but i can get the width a litle longer but then the hieght would

be a litle shorter, because we have a roof under 35°. What dimension would you prefer? It's so small because i need to hide it from my parents .

I will plant 20 seeds because there is a 50-50 that there would be some males and some wont make it so i think if i plant 20 seeds i would have around 5-10 healty females (i

hope so ).

My soil mix:
Potting soil 60%
Perlite 15%
Building Sand 10%
Worm Castings 10%
Pre-Mix 5%

Now here is what i do:

I germinate the seeds and then i put them into pots that are around 5x5x10cm with the root down and keep them under constant light (like this

http://uploadcentar.com/img/th8971marijana.gif but ofcourse in a box with reflecting material) and soil moist for the next 2-3 weeks. The light will be always 10cm from the

plant. On the picture there is a fluorescent lamp, i think it would be good but what wattage should i take since i will have 20 plants at the start.

Now it's the movment time. I will transfer them into 5 liter pots and under a light. Now, witch light would you suggest. I will have around 6 plants in my closet, or do you

think that i can push more plants in my closet? And witch light should i choose and what wattage should i take due to my closet dimensions? I tought that light should be on for

12 hours a day and watering should be every 2-3 days. And that's it about my plants.

Ventilation . i tought about 6 computer fans should be enough, or is this to mutch? 2 for intake, 2 for exhaust, and 2 for air circulation. here is a sketch how would this look

like http://uploadcentar.com/img/4868marijana_grow_box.gif. The air circulation fans would be at the end of the pot and at the bottom of the plants, so it blows directly on the

whole plants, thats why they are under 45°.

I measured the temperature in the room, and because these days it's really hot the maximum temeprature that i measured was 30°C so i think when i'm done with the construction

colder days will come and the ventilation should lower the temperature also. I havent meauser by night but i'm sure it is mutch colder around 22°. So by the daytime the light

would be on and by the night the light would be off, since the temperature must be lower when the lights are off.

Ok this is all folks, please tell me if i missed something and give me answers and advices please. Excuse me for spelling because i aint from USA nor England. THANKS!

...nothing...

love, kp
