Great grow, Bluejeans. I would be very interested if you could list out all of your soil amendment products and in what ratio you mix each into your soil/soiless mix. Also, what kind of soil are you starting with? I was planning to try the good stuff, like Fox Farm OF, Sunshine Mix 4 or ProMix. Where I live, I have never seen these at the local hardware stores. Does anyone know a good website to order this, or should I keep looking for a nursery or Bigbox store that sells them? I also do a little reading myself on RIU on the different potting soil/soilless mixes. I have been too busy researching seed genetic possiblities, which are just endless.
Grandma, you got lucky getting that clone and it turning out to be good smoke. Mad props to your lighting and bathtub setup. Have you thought or do you have a reflector/hood for your lights, you might could get 10% more effective lumens with one. Also, if you built a growbox, you would probably have to run vent fans and charcoal filtering to keep the heat from your lights in the box down, just a thought to help with the cold problem you have.
Thanks for the inspirational work you are doing. Keep the green porn coming.
