Nice, that looks perfect!

I've got a standard canister type filter purely for exhaust smell, it's oversized for my space 1x1x1.2 but I'm consious I'll need to replace it, but I'm desensitized to the smell! Replacing them every year or two gets expensive, are there any that are servicable/re-fillable? Also any good way...

Holy topic resurection, Batman! So Ive got some chemsan home brew kit cleaner (phosphoric acid)... But I've also found this https://www.doctorblooms.co.uk/athena-cleanse-1620689.html which contains hypochlorous acids it's VERY expensive though... What's best for a pre-grow clean of water...

why are they wrapped in plastic?

Lovely pic, looks awesome! bUT... changing out buckets of water with finding a way to support plants while bucket change etc. You can just use a hose and a pump to drain out the rez, and flip it backwards to re-fill...you can just leave the plants in situ. That's what I do..I have a bath tub...

I guess most people here are US/CA, so maybe no rellevant, but I use Shogun ferts in the UK, mostly as they are widley available but... ..they do ferts for hard water and soft water (plus or minus cal-mag I guess), and also different ferts for hydro/coco/soil...

Thats fine. Not too dry, not too wet. Maybe a tiny bit too humid but it's all about keeping it in a sensible range rather than going crazy chasing a number. When you start budding you might want to lower a little bit more, depending on how thic your buds are, but don't over think it,. More...

yeah that's like 18c at night which is fine, it's the humidity you need to keep an eye on. There's nothing wrong visually with those plants, they are plants, they dont grow in perfect symetry. The biggest problem for new growers is thinking too much and doing drastic things that make it worse.

Yes, but keep an eye on humidity, as the plants get bigger they will produce some humidity. What I did was put my fans on a cheap timer, the ones that have 15min segments, so you can have it 100% on during lights on, and then stagger it on/off as needed during lights out.

are you running sterile or organic? if sterile i'd suggest hydrogen peroxide.

Don't over think it, when the plants are so small they are not going to dry out in an hour, just make sure you don't disturb the roots if you can help it. When the plants are much bigger in DWC, in a shared rez, you can't pull them out without causing a lot of stress and damage to the roots...

First of all, congratulations on getting a slug into a Hydrophonic set-up. It looks a little bit like a leech rather than a slug, though. I have more questions than answers at this stage, lol! bongsmilie

I use a pre-emptive maitnenence dose of hydrogen peroxide every week or so into the water, as it breaks down into hydrogen and oxygen after a while. For root plugs I use https://www.hydrodynamicsintl.com/root-riot-plant-starter-cubes-guide/ which I quess is the same thing as rapid rooters?

Then refit with LED lights... they use a lot less power and give off so little heat you'll be worried about getting too cold rather than too hot.

Cool thanks, I ordered this: https://www.themaltmiller.co.uk/product/chemsan-no-rinse-foaming-sanitiser-1l/?v=79cba1185463 I thought it sounded expensive but then I read the dosage is 10ml per 5L of water, so not so bad!

OK, thanks.. Ive only had the chiller one season and not really used it as my grow was over winter, but I've trial run it so its got about 5L of 'rotten' water in it, it doesnt have internal pumps, and it says not to run it dry. Yes according to the specs: "anti-corrosive evaporator made from...

Thanks, This kinda stuff? https://www.themaltmiller.co.uk/product/chemsan-no-rinse-foaming-sanitiser-1l/?v=79cba1185463 I'm worried about the internals of the chiller as it states: Not recommended on soft metals because of the acid nature of this product. A blend of phosphoric acid...

What light are you using? LED runs a LOT cooler than HID/HPS/MH

Thanks, yes I use peroxide as when I'm growing too, so thats my prefered option, how much to use though? The rez (my bath tub :) )I'll need to pump it through will need to have about 30L of water in it to keep the pump submerged. I can see a 1L bottle of 12% peroxide online...would that be ok...

Hi all, I've got some dirty tubing and could do to flush my water chiller out too...chiller is this: https://www.growell.co.uk/products/hailea-nutrient-chillers?_pos=1&_sid=3d31200f8&_ss=r The chiller holds 5l of water internally which will now be also dirty so I was thinking of running it...
