Seen them. Not sure they would work with such a small volume each watering. But I havent read too much about them yet. I'll try to do some reading over the holidays. Thanks mate!

My mate is running between 50-100 ml each run. As most timers run time is minimum one minute, he's using smart power outlets to activate the pump for 10-30 seconds each run.

what are these ?! ive always struggled to find timers you can set under a minute

Just a regular smart plug/socket, like this for example
TP-Link Smart Plug, No Hub Required, Wi-Fi, Control your Devices from Anywhere, Works with Alexa and Google Assistant (HS100) https://www.amazon.com/dp/B0178IC734/ref=cm_sw_r_cp_apa_36rpAbZJEMG2W
It's wifi controlled so you can use an app to pre program your on/off schedule down to the second.
It's pretty awesome in general and can have tons of usage/applications in the grow room (temp/humidity/light/ventilation)

Awsome. Where did You get Yours? I was looking for 8" cap in UK with no luck.

You can get digital timers now that can be programmed to the second.
The problem with the "top feed" diagram a few posts ago is it shows what happens with hydroton, which is less densely packed. The capillary action of coco is much more thorough - it's like a sponge - so it doesn't matter so much where you feed it, as all the coco tends to get a good soaking and flush. Especially with two lines either side of the stem - though even one line would be enough.
I've tried different things over the years, including misters/sprayers and drip rings, but they hardly made any difference and the open-ended lines were always more reliable in terms of flow/blockage resistance.
While you'll notice a good concentration of roots around the drippers with my set-up, you'll also see the pots are full of roots that are very evenly distributed.
You can try whatever system you like, but I can't guarantee you'll get significantly better results - coco is an excellent wick. But hey, there's no harm in giving it a go.

That's good mate - tell it to my plants.

search for a "cycle timer"... I know you're in the uk, so not sure what brands are available, or if they're called something slightly different, but they're easy to come by here.. several of the big grow supply companies sell them -- hydrofarm, c.a.p., autopilot, etc.-- I wouldn't think they'd be hard to find over there.. there are analog and digital versions.. they allow you to set an on time and off time and then that cycle just repeats over and over

So this is the reason I built two frames and bolted them together . . . and then unbolted them and hung them separately. After the stretch, the 8 plants have separated themselves quite conveniently into 4 each of roughly the same height. The tallest are the 2 Sensi Star and 2 of the Acid, all on the right.
You can get an idea of how little space I've got to work with in my attic. That A-frame is a right pain to work around now that the plants are a bit taller.
New fan as well as staggered light frames.
The flash doesn't do them justice. They're all a lovely green. There's not much I can do about the leaf margins, as it's full-on summer now and I have no aircon in this room. The tent gets quite warm during the night - ambient temps will get up to 40+C during the day and around 25-30C overnight, with temps up to 5-10 degree warmer in the tent - and all I have to rely on is ventilation. A lot of Aussies don't grow in summer for this reason, but I've done this before and should be able to manage. Autumn and winter will be much nicer times to grow

Here they are under lights at four-and-a-half weeks of flowering, so about half-way there (theses should go around 9 weeks or so from seed - clones can finish up to a week earlier).

Man, their looking great compared to mine. First grow in ten years and I smoked the first bud yesterday. Nothings better than your own bud haha merry Xmas man! 
Any idea what this is?

Great job @Prawn Connery !
I like having small lights, around 200 watts apiece so I can lower or raise individually if I've a couple of different strains going at once. It makes sense.
I was over at a friend's yesterday and he' got the Acid and Star in one tent and Star 2 Cancers nightmare and CBD Critical Mass in the other.
He offered me acid clones but I'd to reluctantly refuse as I've toooooo many now.
I've vegging CBD Critical Mass seeds he gave me at mo and I've Candida seed here too ffs lol lol
Merry Christmas to one and all

As long as it works and gets you wasted.... what' in a name.??

Hi mate, in a word: excess nutrient. The clawing is due to excess nitrogen, while the tip and margin burning is classic PK burn, which also locks out calcium and magnesium (rust spots, yellowing between the veins).
I'd give them a good flush and back the nutrient off a bit. It looks like you're getting into the latter stages of flowering - how many more weeks to go?

Thanks for the explanation. I agree and it all makes sense.
They have maybe 5/6 weeks to go. They have damage so who knows how long. They are ultra lemon haze auto fem at about75 out of105+days
In hydro in recirculating rockwool..... Just give them straight water for a few days then maybe 2/3 nutes... Right?
Mind you I know this setup isn't ideal. It was a last minute shit show setup I'm just trying to get through this grow and on to the next haha

OK, I thought you might be in coco. When was the last time you dumped your reservoir? I assume you are changing out to fresh nutrient solution at least every two weeks, topping up in-between?
I guess it would be handy to know the rest of your set-up. Like, are you using large rockwool cubes in a flood and drain or NFT system? In which case, simply dump your res, flush the rockwool with plain (pH adjusted) water, then mix a new batch of nutrient.
As to what strength nutrient to use, firstly, how do you think you ended up with excess nutrient to begin with? Are you not changing out you res often enough? Do you think you are adding too much nutrient in-between res changes? Are you using bottle-strength nutrients that possibly your strain can't handle? Additives? Are you keeping an eye on your EC/TDS. Do you have a lot of rockwool exposed to the air that could be drying out and building up salt concentrations because it is not being flushed by design?
There are obviously quite a number of possibilities, but you're best-place to know what you think the issue might be.

OK so I'm in rw cubes. In 4inch blocks sitting in 1 gal containers filled with 50/50 perlite and clay ball.
These pots sit on a flood table and go back into the same feed res.
It's a hybrid medium recirculating Drip feed .
Seemed better in theory. Until the two different wetness of the mediums don't work well together
I feed three times day. 15 min each as this is the only timer I have but there's 8 plants with two lines each and it's 1/4inch lines so it's not gushing out but ya know.
I was raising the ppm not watching the tips trying to find the max for nutes and light for the strain then I added Pk 13/14 from cannacoco for a week. Probably half strength but it was too much.
I lowered my n with my base nutes but I've been using calmag and I seen the other day its got 4%N
So that probably where my n burns coming from
And the pk 13/14
Ive been adding 3tsp epsom salts to the 100l res the last few weeks too as I figured I cal mag def but it's probably just missing diagnosed from the Npk toxicity and lockout
PS I only top up my res with 150ppm tap water 6ph out of the tap with the inline uv light purifier
