the hydro method involved was deep water culture, thats what i use. basically i use fish tank air pumps to bubble the water so the roots can live totally submerged in a mild nutrient solution. if you dont have bubbles, the roots can only live at the top of the water zone, and your plant will die
heres the basics.
MILD nutrients! this is what i use and why
Fox Farms Grow Big, soil type (derp i got the wrong one... oh well, fuckit) set initially for my sprouted seedlings at 2 ml per liter, then eased up to 6 ml/liter now for mature plants ready to flower when i am ready. still well under half the recommended dose, for all the basics and micro nutrients
miracle grow patio used for a little bump in N P and K when growth gets slow between water changes. but only like 1 mg per liter, where the instructions say 10 mg / liter
Fox Farms Big Bloom hydroponics adds a little N and lots more P and K and additional micro nutrients still well under half the recommended dosage.
Superthrive the only magic potion i use, its a root and growth hormone that has a proven track record 1 ml / 4 liters. its a hormone not a nutrient, go easy on it!
i use 5 gallon buckets with plants living in the lid, and a 20 gallon ice chest with a home made cover full of cannabis.
heres a diagram of the 5 gallon bucket:

you dont have to be this elaborate, i used buckets from a home improvement store and cut the right sized hole in the lid for my home made net pots. i used styrofoam drinks cups with holes punched through with a big nail, it worked but after i switched to proper net pots roots grew even faster. (cost $1.25 each and they are re-usable) fill the net pots halfway with perlite (i am currently using coco fiber and perlite mixed but i think the plain perlite was better) plop your rooted plants in rockool cubes on top, cover the rest of the way with perlite. as long as the bottom 3-5 millimeters of the net pot is under water, your plant will be happy.
things to note:
make sure the bucket, tote, or tank is light proof. or youll get algae stealing your nutrients and crusting your plant's roots.
keep the pump ABOVE the water level of the reservoir. otherwise youll have a real mess and a dead pump when you try to change the water
change the water every 2 weeks, and you wont have to worry about PH fluctuations.
remember to include the height of your reservoir when making your plans for your grow.
a long low reservoir is just as good as a tall deep one if you make sure to bubble it sufficiently.
your plants cannot become root bound. they can just swirl in the water till the bucket is all roots, dont sweat it, untill there is no room for water and nutrients. (never happen, dope doesnt live that long!)
if you plant more than one strain, keep them in separate reservoirs, or one might finish early, and you wont be able to remove it without damaging the roots of other plants who want another week or two of flowering.
keep the reservoir cool, but not cold. tropical fishtank temps will work well.
when you get more experience, try pumping the water from the fishtank to your plants and back in an aquaculture system. thats next on my to do list. when balanced right, the fish fertilize the plants, and the plants clean the water for the fish resulting in a true biosphere with no need to add nutrients regularly, or clean your fishtank as often. (NOT SALTWATER FISH TANKS!)
