Yeah, now after you mentioned, I took a new picture with normal light and this time, the propagator seems clean of those colony looking circles... this got me thinking that the propagator was not so clean last time but the white dust from the calcium was just a coincidence and I might have got...

Exactly, those look like colonies to me as well, that's why I posted the pic... but I did clean the grow space before starting out and yes I do wash my hands with soap each time I get in there. I am running a humidifer but I sprayed that with h2o2 before turning it on first time as well. Now...

My girls are currently in the seedling stage, had a high humidity until recently but lowered to 50's right now... A few days ago I noticed something strange on my fans... then upon checking where the fan blows, I saw that a white dust seemed to be forming on my rdwc (currently not in use) and on...

What do you mean? By checking on them like this or not going into dwc right away?

They'll be going to rdwc but I was waiting for their second set of true leaves... do you think that'll be too much of a wait? I don't want hydrotons crushing those thin stems.

I have 6 seedlings that germinated a few days ago and have been doing fine recently but today I noticed something strange in their previously snow-white roots... Some have developed a weird thinning at the tip and turned color, as if they were drying out... but the rockwool is always moist, the...

Your replies definitely motivate me, thanks a lot :) An update on the girls; they actually seem to be doing better but a bit too stretchy imo, so I slightly lowered the lights again. Only the one in the lower left picture doesn’t seem to have changed in size at all but she didn’t die either...

Nope... well, I soaked them in 5.5ph at first and today added a little of beneficials but that don’t count I guess.

I hope so... the growth seemed kind of stunned after noticing this but maybe it’s me being paranoid. Let’s see...

I have just raised the light a few inches higher. Let’s see how that does. Never considered lights might be too close because the par values company claimed seem right on spot for my initial height but it’s still worth a try... I got worried they might not actually be fine because the bottom...

But when I found out they turned like this a few hours ago, they haven't been watered for almost 24 hours? I just increased the temparature in the room. Shall I remove the rag in the dome so it doesn't hold water as much? Do you think there could be any way I could save them from here? After...

I germinated 6 Incredible Bulk seeds and they seemed to be doing fine until some point. Last night I went to bed and in the morning I woke up to what you can see below. I have been using RO water, germinated in humidity dome and kept them at around 65-85RH all the time. The temps have been...

Nice build man! I'd definitely go with their system if I was living in the states... but they do not ship internationally, and it'd cost a lot even if they did. One thing though, I didn't understand why you didn't choose to pump the water to every plant bucket instead of pumping it back in the...

Cleaning them is no problem since I'll already be rinsing the whole system with h2o2 after every run but after @H1ghTime mentioned it, I looked up and saw that airstones is not really a necessity if the system is built with the waterfall idea in each bucket because the oxygen is not pumped IN...

Hmmm... I didn't think I wouldn't need air stones with fallponics. The above picture is from PA Hydro's site and he has a youtube video for building the system yourself, he actually drills holes for air tubes (the green tubes in the picture actually). Now you got me baffled...

Hello! I am not even sure if I used the names correctly, but I am about to build a 6 plant rdwc system very soon... I have come across 2 types of designs, one of which is the very common type that I believe is called "under current", where all the flow is sucked back into the main reservoir and...

Disclaimer: I have never done scrogging either, but have been watching and reading tons of stuff about it so I'll just try to pass on the knowledge I have learned to apply when I'll be starting to scrog hopefully in a few weeks. It is said that if the plant you're growing is known to be a...

You got me worried and I’ve been reading reviews all around... users generally seem to be pleased with how well their grows are even in bigger tents or less watts in similar tents with this model. But I’m still worried as you sure seem to know what you’re talking about... I just hope you are...

Even during seedling stage? What wattage is your light? Could you please share the height you hang it from if it’s similar?

Oh I see... plants do not try so hard reaching up to the light since there is too much of it, from what I understand. So, yeah I’ll be basically growing in a 4x6 space so it’ll probably be more than enough to make the most of the lights without upped co2 as well. Though I was considering some...
