My buddy, "Edward Stickyhands" at work trimming Mothers Finest....
....this took him about an hour....
He says he enjoys trimming and finds it therapeutic. Crack on buddy I say....I find it tedious and frustrating. Got the VK to do myself though as he's out of town now.
And my seeds have all sprouted in my wee hydro tank
The one front left only has one cotyledon....bit weird, no? The one front right sprouted a day or so ahead of the others and has a tap root out the bottom so I'm going to get some larger rockwool cubes soaking.
When pre-soaking rockwool cubes the last couple of times I've kept an eye on the pH of the water they are soaking in. From starting at 5.5 the pH was over 6 after a few hours, presumably due to the lime washing out the rockwool as the main reason for the pre-soak seems to be to wash that out......3 soaks for about 8 hours in a fresh batch of pH 5.5 water seems to work better for me than 1 24 hour soak. With my last 14 seeds I've had 100% germination after soaking the cubes 3 times where a single soak was giving me as low as 50% with some strains. I've had better results with cloning this way too
My thinking behind the wee hydro tank was that by having a relatively large volume of water (~5L) circulating it simulates a much larger and more stable environment for seeds to germinate in than using rockwool cubes in a propagator. Plants exchanging ions with a nutrient solution causes pH to increase and a 1" rockwool cube seems like a pretty small environment with a very limited amount of nutrient solution that I expect could rise rapidly in pH as plants grow and transpire. The tank hopefully counteracts that. Any higher than pH 5.8 and I add a little heavily diluted pH down.
Next time I might try a heat mat under the tank to see if that lights a fire under their ass lol.....or at least not put in cold water at the start. Either way I'll need to find out about optimum tank temps and get a thermometer that goes in water.
