Thanks for the kick in the pants
I think I've got about $25 in this setup.
I'm using an ancient rotary dial timer, right now I've got it set to trip every 8 hours for 15 minutes. Current nutrients are the GH basics as well as a dash of Thrive Alive, since it's just got the seedlings in it right now.
PH = 6.5
PPM = ~450
I tried my best to screw it up right off the bat- the Sterlite plastic is REALLY brittle and cracks if you try to use a large drill. So when I cracked it drilling the holes for the Ebb & Flo fittings, I got to thinking- why not go full cheap bastard and use the water pump as an airstone?
So I then proceeded to drill a bajillion holes in the tray as well as the Roughneck lid. The lid has a raised lip around it, so the nutrients not only flow back via the hydroponic fittings, they also drip through all the wee tiny holes from the tray into the top of the Roughneck tote and then through all the wee tiny holes in the Roughneck tote on down into the tote. No air pump.
I've currently got a couple Red Savinas, a couple Tequila Sunrise, an Aji Chivato, Aji Jalapeno, Spanish Padron, a half dozen real Italian pesto basils, a couple Lemon Cucumbers, and a couple Endeavor Pickling Cucumbers in there. Later this week I'll move the whole mess out in the greenhaus, and maybe that's when I'll add some Hygromite.
I've got a couple spare Autopot Smartvalves, I might just put 'em in a couple more of these Sterlite trays.
