IWS help please

Could you not flip that setup from flood and drain to Rdwc would make for a much easier grow and less hassle if you ask me mate

Not sure what the difference is? Could u elaborate on why it would be easier?

Gone for a little copy and paste as it’s to early for my brain at the minute hope this helps explain it a little I’ll also post the link to this site so you can have a read you’re self. Feed I would up those feeds to at least 1ml per litre of water for those sizes cuttings mate

In a Recirculating Deep Water Culture system, also known as RDWC and recirculating DWC, the roots of the plants are submerged in a nutrient and oxygen-rich water solution 24/7.

The plant is grown in a net pot that is suspended from the bucket lid and contains suitable media such as clay pebbles. The clay pebbles provide support for the plant as it grows, as well as absorbs the nutrient solution for the plant roots.

As the plant grows, the roots grow and descend into the nutrient and oxygen-rich water solution. The solution is actively circulated via a pump through the buckets connected by pipe to the main reservoir, maintaining an even water level across all buckets.

The nutrient water solution only needs to be added to the central reservoir and all plants receive the recirculated oxygenated nutrient solution continuously.

0.25ml per litre of the 3 part feed 5ml of katana roots and 2ml of the silver bullet roots.

5ml and 2ml per litre??? and what is the 3 part feed???

Are you hand watering or is the system turned on?

That silver bullet is h2o2 if you're giving them 2ml per L of that ... That will be your issue. The res will only need that adding at res change and then at about 1ml per 10 litres of water. h2o2 (silver bullet) is a bleaching agent for killing bad stuff.

I no nothing of 3 part feeds, but I'd get them on some food. They'd be on straight A+B for me and at about 1 or 1.5ml/L while settling in.

No the silver bullet im feeding 2ml per 10 litres the katana is 5ml per litre I've attached a picture of the 3 part feed im using.

Im hand feeding yes, but the pebbles/coco came so wet its not drying out hardly and I haven't fes much at all probably in the 2 weeks they been in I've watered little bits about 5 times.

Coco is a hydroponic medium and needs to be wet. You shouldn't be waiting for it to dry out.

You only need the silver bullet in the res when the system is up and running to stop pathogens and root rot.

And I can;t see a word of that feed schedule so still don;t know what nutrients you're using.

I'd just double check ph is correct, double check the ec is where I want it and turn the system on lower the lights and stand back and let it ride. Check daily that the ph is where it needs to be.

They've got roots, they should be ok to be flooded once a day now, 1st thing at lights on.

Apart from that, I dunno.

Hopefully you can see them a bit better mate.

My mate told me keep ph at 5.5 but I'm reading online needs to be 5.8 or slightly above at start?

What brand of nutrients are you using?

Where does that "schedule" come from? Did the guy who sold you the system invent it?

Yes your ph should be around 5.8-6.
I aim for 6 all through the grow and if it's a bit less one day and a bit more the next, I don;t worry about it.

He says he did invent it so the brand is the one in pic below its a 3 part.

My base ec is 0.1 when I add what he says it goes to 0.5

The tri part site says...

Grow 1.8ml/L
Micro 1.2ml/L
Bloom 0.6ml/L



I'd listen to the manufacturers and start there.

Probably flood the system every 2 days for the 1st week and then daily once they've started to react to the grub.

Get you lights lowered... you say 2 x 600w hps???
Use the back of your hand at the top of the plants as a guide. If the light feels a little burny on your back of the hand, then it'll feel like that to the plants. Raise it until it feels comfortable to your hand... Then raise it a bit more for luck.

(or dial it back to 250w if there's a dimmer on it).

Get the temps up over 25*C too.

Hopefully the start putting out some new nice green growth.

Fingers crossed and good luck!
