Pantyhose works great to wrap around the pumps, except when you go buy them the cashier looks at you a little weird.

Zee There are these nylon bags you can get to put your pump inside so the roots don't get in.

Hi
Sort of newbie. 4th grow indoors using hydro and Scrog, although I'm not sure if I've got the scrogging down yet or doing it correctly. Anyway around day 5 or 6 after water change the pH drops down as low as 4.8 also. My air pump is in the tent. I never really worried about it, I just adjusted the pH on those days. Using AN Bloom A&B, Cal Mag, Hydoguard, Mammoth. Because of space constraints and trying to conserve water and nutrient cost, I am using a variation (no timer on the pump) of Stratlogic's Hydro Bucket grow I found on the 420 website.

Hi, wonderful forum. I am a little confused (new grower) why would I need an air dome set up in a hydro system? I could definitely use a dome to cover my pump. The roots seem to always take over and clog the intake.

Right so, I've had one 24 hr period where I have my airpump breathing from outside the tent.
pH = 5.5 when I came home.

Seems much better than 4 dot numbers...

Will manage pH from now until water change again this weekend... where i'll let it settle for around 6.1 at fresh water change.
i'll keep monitoring it though...

additional observations/thoughts/idea's welcome in the comments!

Currently having the same problem, have two identical chambers side by side, both flowering but one side two weeks behind the other. the oldest (mothers that i'm flowering) have a heck of a time controlling ph, the other side has just started doing it (Last Clones). will move the intake hose outside the chamber and see it makes a diff.

Belay that, I forgot I had switched to diff pumps, will setup a test this weekend.

Hey guys,

have had an interesting idea about a reason why pH might drop by a large amount overnight when having switched to flowering.

some background:
before in Veg, I had my lights on 24/0 - stable pH ranging between 5.8 - 6.2.

now that i switched to 12/12 i've noticed that at water change pH is 6.2, and overnight it can drop to 5.2, i've even seen 4.8 after almost 20 hrs.

i have my airpump for the waterstones inside the tent.

while lights are out, plants are known to release CO2 and consume O2.

can it be that overnight, while the plants are releasing CO2, they are basically acidifying themselves through the creation of carbonic acid, the extra CO2 in the tent bubbled into the water?

Carbonic Acid: https://en.wikipedia.org/wiki/Carbonic_acid


you'd think that the simple solution would be: let the airpump draw air from outside the tent.

any thoughts on this?

IC, I'm taking a stab in the dark: They haven't stretched enough to be getting burned by the lights, have they?

Hey, if it's working, it ain't broken!!!!

So on the opposite end, i don’t think I’m going hydro for a while. My soil needed so much less effort, energy and thought. And, the yield was superb with liter bottle sized colas. It was close, but for the work I’d put in, I’m out.

[RagWeedDWC]

RO or tap, I found my tap was giving me a large spread in minerals, switched to RO and the issue was resolved. I think I was over compensating with the increase the change in water.

[RagWeedDWC]

Put me down for Hydro :-), once you go wet, you never go dry.

Control, we don't need no stinking control.. Just a half case of 100ml beakers and gals of strange liquids occupying space.

What up IC... I missed this thread! I totally got sucked into the Instagram black hole the past few months...

I'm still a newbie but I've noticed that I get some yellowing if I don't let my pH range. Are you consistently on the + side of 6? If so, may want to drop it to 5.7/5.8 for a day or two to see if that helps at all 🤷♂️🤞🤓👍

Hey hydro team! It's been a while!!!

So one of my systems have been acting funny and I need some fellow hydro knowledge to see if we can figure this out. I run indoor, sealed room, full hydro, flood and drain, pure hydroton media, GH nutrients. The leaves are fading and new growth is coming out extra light green as well as some discoloration or bleaching is occurring. I'm well versed at my craft and have already added more of my micro nutrients like zinc, iron, magnesium, and calcium. That was 3 days ago and there has been improvement with leaf coloration and plant fullness but the problem has yet to completely resolve itself. Here is a before and after of the whole system sho you can see the slight improvement, but the problem is still present. After that there's current photos of the problem. My ph is 6.0 and my ppm is 950 using gh expert feed chart. Thanks folks!
