When you say pH isn't steady, how much not steady? A gradual rise or fall is one thing but gaining 4 points in a day is obviously a problem. I mean, it could be a whole load of things. What's the temperature of your res? how big is it? what else are you putting in it? does it smell funky? any...

Yeah I've heard soaking.. never done it myself. I rinse them thoroughly till the water running off them is crystal clear, then use them. Sounds like you are having more than transplant shock. pH is going to be the culprit i suspect.

Well, that's not really a system specific question, more a general hydroponics one but I'll go in anyway. IWS is the same system by another manufacturer. I pot based flood and drain with a brain and float valves etc. Your PPM shouldn't be any specific number. It's not a be all and end all, you...

Yeah makes sense. I know when I used a waterfall for my bubblers I had to put it on a timer, 15 on 30 off otherwise it would heat up like hell. Air pumps are better for sure as water conducts heat 7 times faster than air but chilling the intake i'm sure will work well. All airpumps are not made...

I have some IWS which is pretty much identical. What's up?

I'm not a huge fan. Too many moving parts for my liking. f+d with an external res would be the better option, but if he already has the bubblers and doesn't want to buy/make a new system... adding a couple of pumps to turn it into recirculating is cheap, and then just buy a chiller. Overall, the...

Nice work everyone! Last time I made bubblehash I vowed never to do it again, with the effort it took! I fully agree that the 5 bag kits are just not worth it, you only need a couple of different mesh sizes. What I got out of the super fine one was blow your face off good, but the effort...

Does it matter that the reservoirs are the same? or do they need to be seperate, with different TDS / feeds? If they can be the same, your absolute best way is to turn them into a R-DWC with some simple crossovers and pumps, and then fork out the money for a chiller. The initial outlay is more...

What is a super auto?

Thanks for the responses guys! For me, I think the only thing that could persuade me to use them is the very useful point about outdoor growing in less than favourable latitudes. I might actually give that one a go next summer. Very useful that if you only have one space, you can bang veg and...

Hey, does this only apply if you have a smart meter, or can you see that regardless?

lux isn't everything. The reason you got such a poor yield wasn't the amount of power but the spectrum that it puts out.

I've never touched them, I don't like growing from seed. Can someone please explain why autos seem to be so popular these days? I get that it will be faster than a normal photoperiod if you grow from seed, but flowering clones has got to be better surely? I've got a couple on promo and I might...

Yeah.. that's just simply not true at all. It's a signal to the plant to finish flowering. The same reason you see this purple colouring when you switch to 12/12 and the anythocyanin runs riot. That is what causes the colour. It's a chemical within the plant, that is present or not present, in...

It is genetic. You can induce the trait to show itself more prevalently by reducing your temps. You'd have to be doing something seriously wrong to get that colour via phosphorus deficiency, and you can tell from the plant, that simply isn't the case.

also, I don't know what floor your flat is on.. but water comes out of the tap.. and soil is heavy.

I realise here someone is going to say, "well you can't have the same res for that many different strains." Well.. yes.. you can. You use the same base tank for everything, and if any one of them is crazy hungry for calmag you feed it seperately, on top of its normal feed.

Why are you feeding anyway? Surely an automated setup would be preferable? Just get one big res and service everything with one tank. All you'd need to do then is deal with one reservoir. 5 minutes work every day, or even 4 days if you're lazy, or contact restrained.

Just thought I'd leave this here. This is RD's flower room.. Free cookies for anyone who can spot a fan leaf in this picture.... I'll wait. Original video: Flip to 18:30 for the flower room.

Actually scrap that, I just saw how much the net was sagging! haha..
