5 mins on an unmodded is not enough place a dripper in a cup and try it
the flow rate unmodded is around 2ltr hour depending on how its rigged up

It's taking 15 mins to run a liter through one topspin

try 10 mins per cycle harry(if you got roots poking out the bottom) your runoff ec should be close to what your feeding
I'll set it to 10 tonight and check tomorrow. But that means over 6 litres per plant each 24 hours...
Not doubting you but why should run off be the same ec? What does it indicate? And what does the low run off ec indicate?

harry al have to do some digging for ya
it happened to me once and i started getting problems ph runoff was at 6.4 too

my bad harry cut your cyles down
Don’t use pots that are too big. A five litre pot is big enough for a 12 week plant if you have reliable automatic watering. If not, use 10 litres, no bigger.
When the plant is small, water enough so that the nutrient solution just dribbles out of the bottom of the pot. Each week you irrigate so that a bit more comes out as the plant gets bigger. By week 3, you should be getting 30% out of the bottom that you put in the top. That is, for every litre you give the plant, 300mls should drain from the bottom. This is for good water. If you have hard water or salty water, then you can go to 50%, or even 70%. It is important to measure the EC of the water coming out of the bottom of the pot. It should measure between 0.1 and 0.3 EC higher than that going in the top in the irrigation water. That is, if you are feeding at an EC of 1.2, then the water coming out of the bottom of the pot should measure between 1.3 and 1.5 EC. If the EC coming from the bottom of the pot is the same as, or lower, than that which you are irrigating with, then you are overwatering. Cut out one watering per day and see how it looks after that. If the EC is higher at the bottom than the 0.3 it should be, then you are under watering. Add another irrigation.
Just be aware that it is hard to get this right during the early stages, as the plant is so small and the pot so big that the plant doesn’t have much influence on its environment. It becomes easier and more critical as the plant gets bigger.
The amount that you should irrigate will depend on the size of the pot. It is easy to both underwater and overwater. Generally, if you stick to the guidelines above, each plant which is over 3 weeks old will need about five litres of nutrient solution per day, over 3 to five irrigations a day. The smaller the pot, the more frequently you will need to irrigate.

oA lil update and a few pics - crap as ever but there you go. I'm told I can rotate these pictures somehow on my pc but I'm one of the fools who got a new one with windows 8 which is doing my head in anyway. Think I'll wait till the long winter nights before I do my head in trying anything more than uploading.
The girls are behaving pretty much as I would expect - as I already said, I've run this plenty of times - stretched about x2, lil button buds started forming about day 9.
The mesh isn't quite as full as I would like but this set up is planned for 12 girls per tray not the 10 per I have. I bent the tallest branches - the grapefruits - and tied em down to the mesh.
ec is 1.3 now. It's still 0.6 in the run off but they're looking healthy enough. The Skunk Specials never go above 1.5, the grapfruits will take a lil more - 1.7-.
8 but they should be alright on the lower ec.
should also say that I backed off on one feed so they're getting dripped 4 times per 12 hour lights on now.
I took a bunch of cuts from a new mom today. She's 'critical' though I don't know who's version. My agent got her for me - reckons it's "what they're all growing" right now.
I had to drop the SS mom coz the buds just stopped smelling once dried. I mean, they stopped smellin of skunk and just smelled of hay, if y know wot I mean. Potency remains the same but without that smell and taste they ain't worth shit really.
So, I'm off with the critical now, that and a bunch of Sweet Seeds Green Poison I crack a coupla days ago. They reckon they'll be cooked in just six weeks but we'll see .
Thing is, I ain't got the room or the time to be testing for phenos and selecting new moms any more.

sweet set up man they look good. on the subject of flooming.. ive read a lot about it and its apparently the superior method of oxygenating water just as dank demon said.. il post some old links if I find them. good luck buddy!
You might well be right on this, Sifted. GM wrote this stuff 6 years ago and understanding has probably moved on.
TBH, I wanted to avoid aerating the rez coz of raising ph but if it has to be it, it has to be.
I got one of those tall, thin water butt type rez's. What pump would you recommend?
And thanks for your good wishes, man.
yeah plus you ph might change anyway. I wouldn't avoid aerating the rez too much because the water will just go stagnant. plus its good for the roots to have more o2 in the water
Okay SupaFunk.
I'm wondering what pump to go for. Too small and the surface wont ripple, too big and I'll have a fountain - then there's the falling level in the tank.
best do sum reading.

Fair enough SU, You boyz got me convinced!
Go as small as you can get away with, it just needs to be disturbing the surface. As you mentioned, you don't want a great spunking geyser when your res gets to half!
Time for sum new pics and a lil update. As always, apologies for the pic quality. One I've got my head around this dope growin lark i'll do sum work on the camera stuff.
Into week 3 of 12/12 now and the girls love this set up. They're all lookin well if just a tad over fed. EC is 1.4 and I'll back it off to 1.3 for a couple of days.Temps are between 69 and 78f, lights off/on.
I've decided to finish this run on the 600 watters rather than switch to the 1000s. That way I'll see what difference the drip feeding makes after hand watering.
Looking great mate, cannot fault the old coco.
I started with coco when I first moved my thing out of the greenhouse. Never felt a need to change it since though I'm thinking about coco slabs for the future.
