Grow Mediums Happy's first DWC grow.

This is going to get huge!
Maybe a bigger airpump/ a second one!

Hey Solyent

I actually have a second airpump I was just waiting for some more airline tubing to arrive which arrived yesterday.

A couple of photographs just for you here are the two spare 80lph and 40lph air pumps I have (not including the 80lph one that's already hooked up) plus the 30m of airline tubing I ordered. I'll be hooking one of those extra pumps up after this grow is completed.

Dude you are ON POINT! Sick setup and beautiful chiller you got there. Subbed and will be joining for the ride. I wish I can do DWC again but I'll need a bigger space and a chiller. Maybe one day

Best of luck bud! Happy St. Patricks weekend! Enjoy that stout. BRILLIANT :Sharing One:

Thanks Vick - you're a fupping legend you are Cheers for the comment and rep, you just pushed me over the one green square mark into the two green square territory... awwwwh yea!

Glad you like the chiller, I got it years ago doing a home made aeroponics setup made out of 6 inch waste pipe after I got what I believed what Pythium. Never again! Will be getting some silver insulation foam today as recommended by Pop32 to help keep the temps a bit more stable within the actual buckets themselves.

As for St Patricks day, yeah no doubt I'll be getting absolutely langered on Guinness / Murphys / Jameson on Monday (st patricks day) and maybe tomorrow (saturday) too most likely. So if I come on here declaring my love for everyone on AFN you'll know why hahaha

Plants are looking a touch better today after me upping the EC. However it's now 1 week since I put the seedlings into the net pots and they roots still haven't emerged from the pots. I feel like they should be out by now so definitely something not quite right there. I'm hoping with the slightly higher EC they'll start growing quicker and roots will be coming out the bottom soon. Not sure why it's taking so long. The only experience I have with net pots was the 3 inch kind in the aeroponics system I made and using clones not seedlings. They only took a few days to show roots coming out the net pots. I'm hoping because I'm using the larger 6 inch net pots and seedlings this is 'to be expected'. What do you think?

Here's some photos of my non exist roots but more importantly my net pots

Happy, might be that spots come from hot and dry air and strong light.

Hi Gonzo - thanks for chiming in. The temperatures aren't too high mainly sitting about 24c - 27c which is nice and warm but not hot. The low humidity is definitely a concern but hopefully when the new pond fogger arrives.

Also I believe the Root cubes that I germinated in could probably have benefited from being slight lower in the net pots allowing them to get more moisture from the bubbling action of the airstone spray in the DWC bucket below. I noticed the two worst looking seedlings seem a little 'dry'.

Definitely they're looking better since I rose the EC from 0.65 to 0.8 So I believe the EC was too low for too long. I see Seymour Buds uses a light nutrient feed called Formulex at about 1.0 EC so I'll probably copy that strategy next time in order to move past this brown spot issue. On top of that the better humidity next time from the pond fogger will definitely help.

Anyway that's the conclusion I've come to but as always am keen to hear peoples opinions on everything and anything

:tiphat:

the roots should show soon happy :Sharing One:formulex is great for babys ,but only the 1st week or two .

your temps are way to high mate ...18-22 is optimal ...24 might be ok ,but asking for trouble ... 27 is definitely going to cause problems

Might be underfeeding not heat, I agree.

I have had the same problem recently. I am in perpetual grow, and young generation three weeks ago shared the same place with older ladies on full power light, so it was always around 25-28C and humidity was around 30-40% what was nice for flowering but not for younger ones.

I have got little spots on leaves and slow growth also, but might be that was underfeeding as you say, I think I tried with too dry watering regime and maybe there was not enough food available from too dry soil.

I still have higher temps as I would like to and humidity is still a bit low so I went with humidifier. I have noticed, that the place is now a little bit cooler, seems that lights can not heat air so much if humid. and ladies seem to be much more fresh as they used to.

But these little brown spots do not leave my mind because I grow only Think Different and it has not happened before. And I do not like these plants, they will pay themselves out but two are smaller than usual and one is a little bit longer but with too long distances between branches and prone to stresses.

I hope it will not happen again. I hope it was only a coincidental series of small mistakes in growing which altogether harm a little bit.

DWCocha you're talking about water temps right. My water temps are 18-21.5 and air temps 23-27

Day 9

Still no roots showing from the net pots.

I noticed days ago that a fuzz growth was on the air stones and airlines. This is coming from I believe the Rhizotonic so wasn't worried about it at all. I'm wondering now is it responsible for the lack of roots? I've decided to completely drain the system, flush it, clean it and refill with without Rhizotonic and 0.5mpl of H2O2 17.5% to make a dead system.

I emptied the reservoir tank and give it a really good clean with bleach and then a really good rinse after. I ran bleach water through the chiller and hoses for a few minute then flushed it out with clean water. I took all the airstones out of the buckets and cleaned them and sat them in a bucket of bleach water for an hour, then thoroughtly rinsed them. Emptyed all the buckets and gave them a wipe with a potent water and H2O2.

I then refilled the reservour tank and RDWC bucket system with RO water + H2O2.
added:
0.5mpl Plant Magic - Magni-Cal+
1.0mpl Advanced Nutrients - Grow A&B
0.25mpl Advanced Nutrients - B52
a touch of pH down

0.8 EC / pH 5.7

Please take a look at these pictures of the growth and let me know what you think

I should know in a couple of days time if this is the solution to my problem, but so far it's a pretty crappy start to my first DWC The seedlings are not that healthy. I germinated one extra think different and stuck it in a 1 litre pot with coco, feeding the same nutes that are in the DWC and it's doing well, looking healthy and actually bigger than the DWC seedlings haha. So it's also possible that I haven't been top feeding the DWC seedlings enough... However the splashing action of the air stones is really making the stones in the netpots wet so I thought that would be enough? I've top feed a bit but will top feed more until the roots are coming out the bottom.

I'm crossing my fingers and very hopefully in a few days they'll be doing better and starting to grow properly.

Very nice setup Happy, I'll be tagging along for this one, best of luck with the grow!

could be a light leak bro ? :Sharing One:
