Same Jacks 321 mix, nothing extra added. I have Fulvic Acid and Tribus on hand (the two additives that Greengene uses) but I havenāt added them to the mix yet. So far itās been straight Jacks between 1.6 and 1.8 EC.
Iāve never really liked flood and drain setups that let the water flow back through the pump, and thatās the main way people flood from the bottom. (Same line for feed and drain.) That style of setup introduces some problems for me. It wouldnāt have let me run the siphon return which I use to āsuckā debris out of the grow beds. And it also wouldnāt let me run the inline filters to clean that debris up before it reaches the grow beds again. I am sure I could have worked it out, but I have always fed from the top and since The Bucket Company system comes with manifolds + sprayers it just made sense to continue with what I knew worked. I did switch out the red (360Ā°) sprayers that come with the system with new blue (90Ā°) sprayers and that has given me a lot more control over where the spray goes.
Back when I ran this style before I always had algae grow on top for the first few weeks and never really noticed an issue with it. I did some reading around about this problem and the consensus is not to worry, so thatās my current plan.
Thanks man, itās going well so far. Weāll see how the harvest turns out.
One thing to note. Since I have the cameras on in the room 24/7 now Iāve been taking random timelapses to see how the plants react over time. I noticed they are going to sleep about an hour or two before lights out. (18/6 schedule right now.) We discussed this on TheBudLab stream yesterday and the thought is that the plants are reaching their peak DLI and going to sleep early.
The really interesting part of this is that I am only running 4 of the HLG300 v1ās in this room. 1200w over the 8 plants ā most people would say nowhere near enough light. But the plants are saying differently.
More data is needed here, so my lighting friends are sending me a Apogee to use so I can gather some more information and compare the 1200w room vs the 500w tent PPFD.
