@JERgarden, i think also mate, for that time i wil use some guano tea and some green Sensation at the last weeks. Also got my eyes on pk 13/14 but i think that the guano's taste effects are minimal Then. Your journey is really intresting mate! I gonna do something with this in the future. A mate of mine told me about the banana thing. But he didn't make extract het Just layd them around the plants, great results! Maybe its beter to use the banana's as this could it be? The banana produces Then more of that hormone or something due to further ripe
@Hunteq, nice mate, Hope the best in your growth. With the bat guano mixed from the beginning I think your plant probably will ask for nutrients in the middle flowering as mine. The caustic potash is used to obtain the organic content in many guanos around the world, and I was told that some organic nutrients in the market designed for flowering used it along with organic molasses to provide the potassium needed to fatten the buds. Anyway, I will use it in small doses to prevent potassium deficiency during flowering, and let the guano and its nutrients do their thing with the plant and see what happens. I've used banana peel extract with autoflowers and didn´t see any improve in bud fattening, so I assume that their short-life cycle prevents such extract to act properly. Maybe it could be useful in photo strains.
@JERgarden, thanks a lot!! Good answers and defently mind bending about the mineral absortion, will Read more mate! Very curious about your aproach thanks a lot for sharing
Today i started first flush.. the run off EC was Incredible.. 14.0
The ground EC was 1.2 right after flush. Sadly wil do it again.. my seeds have become seedlings and are doing well so far! Lucky me to place Them in redcups xD Will start a dairy soon!
@Hunteq, plants could grow in a soil even with an runoff ec of 4 or 5 (It happened to me with last grows with bokashi and bat guano as soil amendments), but for sure, it will give a lot of headaches (it definitely will raise your ph) and you will have to flush them a lot of times (put more stress on the plants). I just decided to low those soil amendments, and currently i will run a few growths without them.
Regarding the bat guano with caustic potash, I found a master thesis (in spanish) that run some test with that combination in lettuce growths, and they find very nice results in the yields. They used citric acid to extract the mineral part of the bat guano, and use the caustic potash to extract the organic material from bat guano (I will use only the caustic potash). They used 100 grams of bat guano, 100 ml of potassium hydroxide (caustic potash), let them react for 24-48 hours (other researchers in other study let the caustic potash react with goat guano for 7 days), mix with 900 ml of water and then filtered to remove solids. This gave a very strong solution with a ph of 13, so you have to adjust the ph once you mix them with the water. For instance, I use 10 ml in 3 liters of water to obtain an ec of 1.2-1.4, but this dilution and final ec can vary depending on the bat guano composition (be sure your bat guano is phosphorus-rich one and not nitrogen-rich one). I have never used it in a full-flowering phase, yet I used it in the last 2 weeks of flowering of my meringue diary and buds fatten a little bit more, so for sure I will do the full test with this strain. Let me know if you need something else. Take care, mate.
@JERgarden, iam very curious What you pull off with that blend, never heard of caustic potash can you tell more?Think next time i go 150gr on 25l. A mate of mine told that it light alsof be something else in the guano messing with the electral field of the EC meter maybe i Let one Stay in it to be sure. Also i mailed pragron (the brand of the bad guano) that they'r max recomendations are brutal over kill even the 1/4 of it seems to much already.. i want compensation since nothing grows on it in theory
@Hunteq, yes mate. Try to flush your soil as many times as you can before transplant your plants. If u want to mix the bat guano from the beginning, next time just use it in the soil mix at 1% (in your case would be approximately 500 grams in 50L). I have 3 other cbd-rich plants that I will use to test my own liquid flowering fertilizer made with bat guano diluted with caustic potash. I think with this methodology I could control more easy the EC that I give to my plants.
@JERgarden, thanks for the advice! Emm they have to become seedlings yet. They are in seeding soil in a redcup placed in the 25l pots.. think once they pop up i lift Them out and flush the soil. But i wonder if there would be Anny badguano left for the feedings
