Hinky's Brain Strain Grow Log

I normally wouldn't do this as I'm generally not organized enough, compared to most grow log posters. But since this is what a couple Brain Strain 7 Pots looked like 9 days after putting seeds down, I thought I ought to document this particular grow-

Seriously? Jebus. I'd started a 100 cell tray with a production run of jalapenos and some more giveaway tomatoes and a test run of some of the seeds I received from Ecuador. I had 2 empty cells so I figured what the hell and tossed a couple Brain Strains in, figuring that since they take so long to germinate I'd just leave them in for a few weeks when I go to work and hope that they might come up when I get home. So I'm clearing the jals and toms and everything out of my germination station and notice these, looking like this. Wherrrr? I doublecheck the spreadsheet and sure enough, unless I REALLY screwed up my starter layout, I somehow managed to get 2 Brains to pop up like this in 9 days. While I attribute this to blind luck, here's my standard starting setup-
  • Rapid Rooter starter cubes
  • Well water (85°F)
  • Standard seed starter tray with low humidity dome
  • Seedling heat mat (no thermostat) on top of foam insulation
  • 8 T12 48" fluros on 24 hours
  • 2 each, 5 watt LED 465nm

After 13 days, I placed 1 in a deep 4" pot with soil and the other has gone into a 4x4 rockwool cube-

A bit earlier than I would like but I had to leave home, so it was now or never. Roots were showing through the cube a couple inches, so it was probably not too early.
Though it's a bit hard to tell, the stems show some pretty deep anthocyanin coloring. The plastic cube cover slipped off when I was moving everything- I know it's going to be an algae covered mess when I return!
Nutrients are GH Flora, approximately 1200ppm, pH = 6.5. Well water start ppm is approximately 130ppm. 10 gallons of nutrient solution. Tray flood is 15 minutes every 12 hours. I realize that could be a bit aggressive and damp for this early, but as I will be gone for 2 weeks I thought it would be best for the situation.
E & F is in the greenhouse where nighttime temps have been averaging 60°F and the exhaust fan thermostat caps daytime temps at 80°F. As nighttime temps rise, I'll raise the exhaust fan thermostat temp as well- I'm aiming for a steady 20°F differential. Also, the nutrient tank is directly below the tray, and the tank itself is sitting on a propagation heat mat.
 
Looking smart. I don't work in ppm but 1200 sounds quite strong?! Keep us updated - I'm amazed by the number of people starting in hydro this year.

I think everybody had great germ rates with the BS seed I shared, glad to help out. Pretty amazing to see BS plants in every part of the globe from a single mother Brain Strain still alive in the backyard. I also think that the 1200 ppm is much too strong for those little guys, good luck with the grow.
 
Gah, you and your fancypants metrics! :lol:
Here's a conversion tool for going from ec to ppm and back again.

1200ppm = 1.7143 ec

It is a bit strong for a seedling- GH shows seedlings at 490ppm (.7 ec) and Mild Growth at 1210 ppm. I'd started a few other varieties at 1200 and they haven't shown any burning yet, so I decided to just keep it where it's at for another 2 weeks. I'm not adding anything else to the solution for the time being, just the base GH Flora 3.
