Quick update on the tomatoes. They are growing at a fast pace now and here is what we have so far.
Today was nutrient change day so here is a good shot of the roots. Some of them are over a foot long!
Energy Use update - Since upgrading the lights to two 23w CFLs a larger reflector hood and adding a fan here are the new numbers on power usage
- One week it used 9.776 kilowatt hours of electricity @ 12 cents/kwh equals $1.17 a week.
- One day is uses 1.397 kilowatt hours of electricity for and average of 17 cents per day.
Also the lettuce was changed out. This is a new seedling started a few days ago. Roots are already poking through the bottom. Instead of soaking the rockwool cube in ph neutral water I soaked it in ph 5.5 nutrient solution. I used the nutrient that was already in the system on my last lettuce try. 1 gallon with 2.5mL of Micro, Gro, and Bloom.
