Advanced nutrients claim pH perfect technology. I'm using it in rDWC currently and the pH is 7.5!! I contacted advanced nutrients and they say that their nutrient is available between 4-8ph and not to pH the solution. Should I believe this? The plants are fine it's confusing.

If I had 2 clones and vegged them the same length of time but one is in a 20l/5gal and the other is in a 36l/9gal would the yield be bigger in the bigger bucket or not considering they had the same length of veg

Second run at rdwc, the Plants have no life in them. They are droopy and some of the leaves are crispy at the tip. We are having a few freezing cold days here at the moment so I put in an oil radiator which I've noticed has now caused the humidity to be down at 30%. I also changed my res two...

This started when I moved her from the early veg dwc tote to the large rdwc alien system. It's a couple of plants that have done this. My water is on point my lights are dialed back I don't know what is happening. The only thing is they are in 4" rockwool cube that I've never used before. Should...

Hows it going on my second run from seed here and noticed these infants with brown root tips. Also a bit droopy any ideas. My first thought was maybe the water is too far away from the bottom of the net pot and it's not getting much splashing so I filled up some water just now. I've also...

I'm torn between which system to get. The aero is pretty much silent + no need for air pumps or water chiller. It seems like a no-brainer to go aero. I never suffer from power outages so I don't need to worry about that. The main thing is does aero create big yields like in dwc? Do you leave...

Hello I haven't had plant issues in a long time but that was in soil. I want to conquer rdwc. What is up with this plant, the rest seem ok although they are all starting to get purple veins in the leaves. But this one is also droopy. I'm using regular tap water starting ec is .3 after nutes the...

How long would you think i could go from seed in a 4" rockwool cube. I'm hoping to go 4 weeks from seed before I transfer it to the rdwc system. Wondering also what kind of watering practices would you have with rockwool

I'm just about to order an alien rdwc what can't decide on whether to get a 20 litre pro or 36 litre pro version. Would the difference in size really matter that much. Is it so you can veg longer. I don't really want a veg that long. Also is 8 pots enough for an 8x4 area

I use autopot and noticed a massive infestation of springtails in each tray. The plants are just about finished so im not to worried but I was wondering if there is something I could put in the res to kill them. Also do they lay eggs? Would it be a better idea to harvest then spray insecticide...

The filter on my res got clogged up while I was away for a couple of days and came back to this. It's the start week 7 of flower. The water is flowing and I turned the lights down to 25% do you think it will recover? They are in lightmix soil on the autopot system. Falling over it's so dry

Just wondering if anybody did the course? Was it worth it? I was thinking about doing it, $1500 is a lot though and I grow dank shit anyway. I suppose it's not really about learning how to grow but more about the science of it all.

So I grow in a shed and have an inspection next week. I use carbon filters that blow the air underneath the shed and that ona gel stuff underneath the shed aswell but it's day 42 and shit is stinking and needs a couple more weeks. It's not smelly from a few feet away but up close you would be...

Holy shit like. I was dumping a load of bottles down the toilet that I haven't used in a long while. Poured down a litre of pH down then without a second thought started pouring down pH plus only a little went in, fuck me there was a small explosion in my toilet, smoke and shit started filling...

Hey I am doing a sog setup and really want to start using drippers instead of autopot. The clean up involved after autopots is killing me. Need to make things more simple. I figure I'd try drippers which I've never tried before, is there any tutorials available?

Simply put are these Hermies? They are in week 2 flowering

I'm finishing up a double stack from compound genetics, I'm wondering can I take a clone now and root it or would I be better of re-vegging the whole plant after harvest of course. Reason for it is I can't get seeds for this anywhere for some reason and it's flaming .

Last couple of grows I've noticed these little white spots. When I look under a microscope it just looks like dust. It hasn't done any harm the buds are fire the plants are doing fine but wtf is this

Wondering if 2 lbs is possible using clones in a 4x4. I have a mars hydro fc6500 720w on full power. Going to use the autopot tray system with 16 clones sort veg sog style to see what I can do. Most I've done so far is a little over a lb with 4 plants 7 week veg. Need a quicker turn around. How...

Hows it going. The demand is crazy and I never have enough. I'm not into being greedy more into trying to keep people's jars filled instead of always waiting. My setup is a 4x4 veg tent and an 8x4 flower tent. Right now I veg 8 plants for 50 days, flower for 60. So every 60 days I'm harvesting a...
