I have the same situation, but the temp in my reservoir has always been at 65 degrees. I didnt think it was even possible to have this issue at such a low temp??

68? I've read several times that 65 was optimal.. :wall:

Yeah, the roots on a couple plants started looking a bit dark today (this happened last night), thats why I asked. thx That's comforting to know. Things are much better now with the higher water level. Thank you! Sweet. Nice and inexpensive. I saw another one once upon a time that...

bump............

My power was out for about an hour, so therefor my plants were all without air the entire time. The mothers, some vegging plants and some recently cut clones were all without bubbles. How long can roots be submerged in water without air in a DWC system without issue? The power was out here...

That would be tough, but it would certainly save me time, money, nutes, and water in the long run. I could probably do a 6" recessed top and then one that sits on the top, but there wouldn't be any in between. thank you

Putting channels wouldnt be an option. I have a pond liner in the box and I am not sure what I could use as a divider that wouldnt rot or rust. Illegal Smile.. Sorry about hijacking your thread here, but happy to see that I helped a few people with finding that 950gph pump. Let me tell...

Main thing I need to know now is how deep SHOULD it be? I could remake a top that can be recessed into the box, but before doing so I would need to know what the best height would be? It's at 14" deep now. 10"? 8"? What would be deep enough? thx

Awesome analogy. Thank you! I have never grown anything, so I think I went a bit overboard with it. Its for me and a few friends (and friends of friends), but didn't mean to go "commercial" with it. Hoping to pay for it and get myself a free supply, thats my goal. Doing a SOG though, at...

It would be impossible to make this one smaller and cost prohibitive to make a new one. For now at least. I spent a lot of money and time making both the box and the custom made top. The box is 14" deep. Which is not all that deep. But it's 6x4' long and wide so it takes a ton of water to...

2 questions of my own. This is my 1st grow and am now ready to transport to my flowering system. #1. I built my system a bit larger and deeper than it needed to be (it's a homemade box). So it would take me 200+ gallons to fill it up completely. I simply cannot do that, especially if I am...

I can be. I have 2 of them running in my BEDROOM (where my plants veg) and the noise is more than tolerable. I know they are on, but it is not very loud, well, not as loud as some make them seem to be. Put it this way, I cannot hear them outside the room when the door is closed. You just...

Do you think the new roots will pick up the slack? I am hesitant to cut off that main root, but if it's dead it's dead (nearly dead at least)

I've put putting a lot of H2O2 (35%) directly on the root mass. It seems to of helped a little bit, but they still arent looking 2good. yeah, maybe i will give it some more time. just wondering if leaving all those dead roots in there was a good idea. thx

bump.. ive gotta know how to proceed

While changing the water in my DWC system, I came across a personal issue that simply could not be postponed or ignored. So the plants just sat out of water for 2-3 hours. That seems to have caused the roots to die. The main shoots at least. Maybe it was something else, but this seems to...

Ah.. Well, thought I read somewhere that 80-90% was best for clones. 60% being best for veg. Not positive though. Either way, heating mat is not an option.

GREAT! Thanks. I'll drop the temp then. I just read somewhere that 75 was best, but I can't argue with 100% success.

There is no "under" to put a heat mat. What you are looking at is a bubble cloner (DWC). My plants are dangling over water. I keep the water heated to a constant 75 though (should I go even higher?). So considering that I cannot place a heat mat under them, is the heated water and the...

having too much humidity for new cuttings? My 1st batch of clones did not go too well. The humidity here is never over 20 (desert climate). So this 2nd time around I built me a homemade dome, but even that wasn't enough to get it up high enough, despite constant misting. So now I just...
