Just a quick update on how the hydroponics is going. So today the system has been running for just under 2 weeks and I’m starting to see some good growth coming on. I would have like to seen this growth in the first week. I think the lack growth could be contributed to 2 things; one being that its not getting enough sunlight, and two that it may need of full dose of the hydroponic solution.
The roots of the pak choy are starting to show through the net cups 
Pak Choy in the hydroponic, which had been going for nearly 2 weeks
What am I going to do from here? Well as this is an experiment, I will be leaving it where it is until the pak choy is finished growing and then in the same position I will try again with a full dose of the hydroponic solution. Stay tuned for more updates on this!
