Hello everyone dwc newbie here nice to meet you all

Welcome mate.

I'm a dwc noob too. From what I've learnt up to now it's a cry easy way to grow.

Keep water temps below 20 (ideal is 18)
Nice big air pump
Water changes every ten days
Keep Ec right.

That's about it.

I am trying to grow with dwc and don't seem to be having much luck, my plants are 18 days old from seed and looking like they are going no where. I am dwc 20 liter grow buckets 5 of, led 200w x 2. Temp of room 21 - 24 degrees. water temp between 19 - 21 degrees. Ec 0.9 and can't bump up any more yet as plants are looking like they have had to much any way now have when over a little touch from recommended bottles, growing with hydro max A and B silicone+ Oxy plus and CANNA RHIZOTONIC. Light are on 18/6 with no interruption in 6. Any help would be grate

What air pump are you running?

Your Ec sounds too high. What's your tap water ec?

Also are your LED s really 200w or do they only draw 100watts from the plug? It will say on them somewhere.

Also I'd lol into using a nursery system for seedlings to keep them closer to a light.

If you have small plants in a full system and you're only using two 200 watt lights (which could only be 100w each) then you have very little light for how far away it will be.

Are your plants thin and spindly with little growth?

Rapid root system is what I am using, leds are defo 200w prakasa ones, tap water is 7.5ph

[Johhar]

this is one of them but they all about the same

[greengiant]

I think with your lights not being close and not overly powerful they may stretch or just grow slowly.

What pH is your water in the Dec system? Plant looks hungry. 0.9 ec is way too high.

Empty your system refill. PH the water to 6 or atleast between 5.5 and 6.5 pH.

Ec to 0.2 above background ec.

You get your background by measuring the water without any nutrients. Mines 0.3 at the moment.

Also best water temp is 19 degrees with a 1.5 tolerance. Either way to keep it in line.

So your led system is a 200w prakasa? Their website. Mentions 30cm between plant and the light.

It's equivalent to a 400w hps.

I have a few seedlings that size they aren't in the rdwc system yet. Still in rooters. And I certain haven't fed them.
