First, im living in a 3r world contry, I mean, im limited in some materials and i already read a bit about grown indoors
1- i would use only one light (metal halide) 400w 220v, but im forced to use this light with 110v because my timer only work with 110v...its this a problem? its for 3 plants.
2- what alternatives i have for fertilizers? like at said, im limited here, i dont have products like flora grown... or i can try to buy some that contains NPK?
3- what's the germination method with the most successful rate?
Go organic for fertilizers since you have trouble buying the typical stuff. Chicken shit, rabbit shit, bat shit, do some research & you will find something in your area that will work. Dont ask me what to use because I dont know where your at or what's in whats available. Research & you will find something available I'm sure of it.
Soak seeds for 24-48 hours in a small cup of water, they will probably crack open by now, Move them to a damp paper towel folded in half in a plastic bag somewhere dark so the towel doesnt dry out too fast. Just damp not drowning or they will die. They will continue to open up & grow a tap root inside the towel. Plant them tail going down.
Bam done son! your ready to grow 700 pounds of ganjabud marijuanas.
Germination Methods are Many .. and most have a good rate of success,the papertowel method
is popular and if done correctly works well. I just soak them in water with a touch of H2o2 not much
like a drop ..But you can read up on that as well here and around the Net..find what works for You.
Depends on how big you grow them. 600 watt ballasts & Single end 600 watt hps & mh bulbs are both readily available throughout a large portion of the world that would probably be the easiest thing for you to source.
Is this going to be strictly indoor ? Or do you have option where it can get some natural sunlight?
In a pinch 220v ballast can be wired to run 110v but the output will suffer, the light will flicker.
