The slow drip at spout stopped! I found it was barely tightened. I had to really, really tighten the crap out of it. I just read more about how safety was in mind when designing these and they should be safe. Kinda weirded out suddenly but read that. It does better than anything else I came across considering that.
Just being collaspable is sketch but I also felt the overkill. Thinking about how vegging for 60 days in 3 gal vs 1 gal would be, if I can down size and make my setup more normal, just tough that the size goes from 25 gal straight to 60 but using 55 at most. Having the capacity is nice even if I had smaller pots.
Anyway I went ahead and did 1 gallon, 1 gram pool shock for 45 gallons fertilizer. Lets see how it holds up. No need to dial in halos so it should last. I cleaned out the drain tub, slimey but the fertilizer reservoir was ok to refill. I used a trash bin with dolly and pump to transport the water and it made it much easier.
