Inside your grow bucket, drill a hole and insert some pvc and of course use silicone to make it water tight or use fittings for this purpose...The only thing I have ever had to do with aquariums is watching fish swim in them
I could use bulkhead fittings to solve the overflow issue, but at $10 a pop and needing 8 of them for this setup, I couldn’t justify the expensive for something experimental that may not work not to mention, they don’t seat well on rounded surfaces like bucket sides.
Once I get the 1-way valves installed, it will solve the issue with airlock causing flow restriction. As it stands now, I can get things circulating with minimal risk of flooding, but the level in the buckets becomes too high, I want to keep the solution below the net pots
If this works as expected, and with minimal or zero issues, then I will invest in making the system the way I actually envisioned it. Basically, the entire system contained in a single tub with just the top, holding the net pots, being rotational
Morning Fred These days I am smoking Cluster Bomb and Blue Dream...got pounds of it but it’s all i have on hand atmComing along nicely Celt, what are you buzzed on this morning? I'm vaping a blend of Gelato and Afghani. Looks like you're in for a busy weekend. Stay stoneder.
OK, caught up on some other things and can come back to this now
Same idea as this photo...
The pvc pipe is your overflow.
The center blue bucket is your sump.
Water height in grow buckets never change, only need to top-up water/nutrients in your sump only.
Of course make sure the water coming from the sump into the grow buckets is above the overflow ... in yourcase thats already in place from your photos. So that will be easy
Thank you Celt. That is just the information I need. I will dip into your bluedream pleaseMorning @Carmen Ray and welcome, pull up a chair and help yourself to the Blue Dream and Cluster Bomb in the jars
Lets see if I can address some (or all) of your questions/concerns
LABs produce lactic acid, the smell of sour/fermentation, as they grow and multiply. This is a natural defense mechanism. LABs thrive in a pH of ~4, the pH of lactic acid, but other bacteria don’t do well in such acidic conditions, minimizes competition.
LABs are great for organics, in small does too much of a good thing can be lethal, pure raw LABs can and likely will kill your plants due to the low pH. A tablespoon of LABs per gallon (4 L) of water is plenty and will not hurt your plants, raw will, just ask me
Now having said that, you can make nutrient supplements with LABs. Say you wanted a N boost. You could use LABs to digest some blood meal making a N supplement which will be too acidic to use without treatment first. To use, after the LABs have done their thing, you would need to boil it to kill of the LABs, then add enough lime (or other basics) to bring the pH up around 6.
As for things growing in/on top of your LABs, it’s likely either yeasts or fungus. Both of which will aid in breaking down organics, yeasts break down carbohydrates (sugars) making ethanol, and fungi as a group, feed on anything and everything Fungi are the first step in breaking down stone into soil.
If you are going to be adding a tablespoon or 2 to your water, use it as is, but if you want to use the LABs as an actual feed, then I would suggest boiling and adjusting the pH before giving it to your plants
So long as you don’t smell rotten eggs, it hasn’t gone septic. The dominate species in your brew will dictate the smell.
LABs has a distinct smell and if you have made your LABs by fermenting milk you know the smell, same smell as the liquid that forms under the cheese. It’s a sharp sour smell. In a highly aerated system like what I have setup, because the bacteria are multiplying so quickly, the solution actually fizzes when left sit idle
Yeasts are our other means of fermentation and as they produce alcohol and CO2, they will smell of ethanol or sweetish like over ripe fruit and will fizz as well. Kombucha tea is a good example of this type of fermentation.
