my gravity fed air atomizing aeroponic system

You could also fill a large measuring cup and fill your lines with the liquid and determine the volume of the hosing. Or take the ID (interior diameter) and length and determine the volume of a cylinder.

Pretty sure flow meters can easily be bought and attached to a compressor line, it'll tell you in liters per minute how much you're using.

i wonder how seed55 is doing he was working on a similar system when i was starting all this. i remember him saying he bought the smallest flowrate nozzles. i will try pming him to see how they went

i figured out how ill measure the water used

ill take a 20 foot long clear line and fill it completely with water. then ill run it for 10 seconds and mark how many feet of water was used. then ill fill the tube with that exact amount of water. and empty it into a scale. i will determine the weight of the water and then convert that to milliliters. as one milliliter/cc = 1 gram
that could work as long as the line is horizontal and not vertical in that the nozzle has to fight 20 feet of gravity... ;)

damn!!! i forgot to bring my camera but

i saw the plants again today. and turned my timer down to 0.5 on timer setting from 0.7 timer setting.
it was 80+ degrees for a few hours. the roots are at least 5x as long as in the previous pictures now.

i have some roots that i have dubbed "super fuzz". i notice most of this super fuzz. appears right next to the neoprene collar where there may be some shelter. i hope this isnt an indicator of to large of droplets. im going to try cranking the air pressure up slightly to see if this makes smaller droplets which produce hairier roots.

ive seen roots like this before in soil plants. it was on roots sticking out the bottom of pots, where the plant hadent been watered in a while and was sort of dryed out.

i just hung my camera on the door nob so i probably wont for get it tomorrow, no promises though
Good stuff! The goal is to have most all of the roots covered in the fine white velvet... ;)

im a little lost, i think you mean if im going to test this in siphon mode i shouldnt have the nozzle 20 feet above the line right?
actually the building im in is around 20 feet tall, so i was thinking of taking a glass of water up on a ladder that high and filling the line plump full and then running my nozzle for ten seconds to emuluate a 10 second gravity fed burst.

i was looking at g loves threads again and i dont think his roots were very hairy what do you think? they seemed a lot more fish bone like than fine hair like.

although you cant argue with 1.7g per watt, if that was anything more than bull shit

not yet gonna let my tank run down then fill it up to 300ppm 5.7ph. real numbes not ec meter numbers
waitin on my calcium nitrate. gonna pick it up monday

and dude its not cool posting my high school yearbook picture on here take it down buddy!!!
I know its wrong. But I'm beyond disfigured in the face, so I found a handsome picture( you obviously) and used it. Sorry for stealing your likeness..:)
Hows the system running?

it runnin pretty good no hicups. need to find a tissue analysis for wandering jew so i can make a fertillizer for these plants. cant ever do anything simple you know.

i missed this post, this makes the most sense of any idea yet.only ill alter it a little bit by just filling my feed line completely with water and then putting the hose in a bottle with 500 grams of water.

i picked up my resevoir today and noticed that theres still about two gallons of water in it. on friday im going to wash out my gas can and fill it up with DI water and enough fertillizer to bring it up to 250ppm and ph 5.7. and raise it 50ppm every 5 days. gonna add 1ppm chlorine as well

this systems pretty cool. i turned my on time down to 0.3 seconds today. my off time is still at 10 minutes. wonder what would happen if i turned it down to 15 minutes off. i should be at a quart a day now

i wonder how the other nozzles work out. im thinking of ordering either the 0.5 or 0.75 gallon per hour nozzles. there only $24 a piece might give it a go. wish i could talk to either seed55 or fatman before i do.

just checking in.

good news. i noticed alot more fine hair growth.
bad news. no pictures, and i noticed the terminal meristem, on a lot of my plant is rotten. ill just have to wait for the auxillary buds to
start growing before i can expect much top growth.

gonna make 3 gallons of fertillizer tonight

after yesterday im about ready to give up. i had three different climates.

from 5pm to 7AM i have what i call the night period. its about 60F or a little warmer. they dont need nearly as much misting. i think i would do good with 0.2 seconds every 10 minutes with a few 30 minute breaks. i find that i accumuate huge droplets in the morning that fade away in the morning. as transpiration increases

between 7 and 9AM and 3 to 5PM i have a transitional phase where i think 0.5 seconds timer setting and 5 minutes off would be good

then theres 10:30AM to 3pm all hell breaks loose. i wasnt able to find a setting that worked out for this senerio in the time a lotted. i sort of gave up

other information. my system is on a heated bench. its pex tubing coverd in pea gravel with thermostatically controlled water recircuating. im thinking of elevating the system off the bench because it seems to hinder my daytime performance.

so i decided im not gonna constantly change the settings anymore. im going to set it to 0.5 seconds on and 4 minutes off. and if theres a hot day ill just crank it up. in a month or so when i have a huge root system ill try to get the velvet roots. until then im just not gonna worry anymore. i have way to many projects i keep getting sidetracked on. mushrooms, tissue culture, school, work. ill probably not update this again until things really get going, and i have some thing to show

so things are going well. im still at 60F most of the time, however today it reached 75F.

i actually just started fertillising for the first time about four days ago. im feeding GH maxigro, i started off with 3ppm RO water. added a tiny bit of maxigrow to achieve 190ppm.
i then checked the ph. and oddly enough the ph droped from 7.0 to 4.5. i didnt have any sodium hydroxide mixed up, so i added a little baking soda, until the ph was at 5.6.

i did i before i went to bed. when i woke i checked again and was at 5.7ph and oddly enough 147ppm. im wondering what happened. i mixed my fertillizer up in a clear container, and there wasnt any insolubles at the bottom that had fallen out. maybe my meter lied.

anyways the roots are now about 6 inches long, they have really exploded since i added the fertilizer. were at about 3 inches 4 days ago
i was actually running tap water before. scarily enough my ph was at 8.1 and 800ppm.

i made some improvements. i added a inline john guest 200mesh filter. i also taped a piece of black plastic over the window. to avoid what has been
described to me as light pruning.

intresting story. when i filled my 5 gallon gas can with nutrients. dropped it from a height of 3 feet onto my chamber. it damaged one of my plants slightly. gave two others a bad hair day. but caused no damage to the foil faced styrofoam walls of my chamber. this is some tough shit.
