I’m “learning” to use rockwool. Right now I’m testing it with some basil seeds. :)

The rockwool is soaked in water. Do I spray the rockwool to keep it wet? It seems really moist days later.

So far no sprouts. Not sure if I should cover the rockwool with something for some darkness.

Suggesting please.

EDIT: After adding only a few ml (5-10ml) to get the PH down from 7.0 it instantly went to 3.5 instead. That happened a few times already and it's damn annoying....

Hello everyone,

I haven't really figured out how to dose PH Minus yet and I'm wondering if I'm doing something wrong or if this behavior is normal?

I did a water change yesterday at around 6 p.m. First I just filled it up with water to rinse the plants for 2 days after adding too much nutrients.

Then after the water change I used PH Minus to lower the PH value to 5.8-6.0 and it remained stable. Today I looked in to check the water and the PH value has risen to 7.0 again? How does that work?

I use "Canna PH-Pro Minus Growth" and there are about 70 ml of PH Minus in 100L and the value still went up a lot? No, it's not the measuring device, it was checked with 2 others.

Maybe someone can explain to me how the PH Minus works.

Just switch them from a smaller tent 60x60x160 to a 120x120x200 currently starting week 5 tomorrow I have 6 but two are two weeks behind and using a Omega Black 720watt led light

I had a male and female Sweeties plant that I set up in a tent on their own specifically intended to create a bx1 backcross and get a nice seed stock. How do I know when to harvest for mature seeds. I know this will be different than harvesting for flower to smoke. I normally harvest at 8 weeks 56 days but I took a beach at that and the seeds were still immature. Is there a way to know they are ready?

Hi all! I’m interested in getting into hydroponics without making much investment until I’ve at least got the basics down (I’m known to kill cacti). I’m a little confused about how I go from the seed to the sample part where I can actually plant it in the bottle and how I can do that as DIY as possible (saw something like this that I could use instead of a net pot - https://www.instructables.com/Simple-DIY-Hydroponics-net-potbasket-from-recycle). But what stage does a seed/sapling/plant need to be at for me to put it in there? I started sprouting some lentils and figured I can easily try that even though it’ll be really small; would that work? I want to avoid dirt as much as possible.

Also, I drink a lot of bud light platinums which come in this dark blue bottle - do you think that would be enough protection against sunlight, or would it still need a cover?

I live in an area that uses chloramine, has a ph between 8.4 and 10, and an EC of 0.50.

I'd like to get an RO filter that has a carbon pre-filter because apparently the chloramine will eat the membrane of the RO filter otherwise.

I'd also like one that has economical filter replacement. How standard are filters?

It'd be nice to have the clear canisters to be able to see how dirty they are.

I don't need a bladder tank because I'll probably run it to a float valve and then shut it off if I'm not around.

Anyone have good recommendations of what has worked for them?

Hey I was hoping someone can give me advice on what to do for my hydro grow. My sprouting is already looking like it’s dying and I’m not sure what I should do. Any tips or advice by any chance anything will help. This is the 9th day of veg
