I grow mmj for my S.O in a very small space. a single planter seems like a good way to get more soil in a limited space. you line yours with a tarp. do you have any kind of drainage holes in the bottom?I wait until the top 2 inches of soil are dry them water until it flows ot the bottem of the pots into a pan they sit on.good drainage is important for proper soil aeration. yours looks like a closed system with no way to monitor water level in the bottom layer. if you are reusing soil then someway of flushing salts out of the soil between grows may be helpful salts build up form fertilizers over time. if you prevent soil from getting into your rock bed than it seems a simple pump,timer,reservoir system could be use to recirculate water and nutrients from the rock bed to a drip irrigation system automatically while you were away and could not tend to your plants.just my 2 cents worth.happy new years and may this year be very prosperous for youNo we didn't but that's a good idea for next time.
the clay pellet layer is about 3 inches thick.
There's pro's and con's to bed growing, but for us it's a huge time saver.
feeding is so much easier, and less frequent, it's just one lot of potting up rather than multiple.
We are also going to make a dripper system for each one, should we be away it'd be very easy to automate.
Cheers!

I wonder how it would work to have some LED running longer hours like 20/4 and then supplement with HID during the cooler hours (maybe 12/12), like in combination with each other. Might be something worth trying...
