1. Student volunteers harvested kale and basil before disassembling the indoor NFT system.
2. Reservoir lids for outdoor systems were painted white in order to deflect sunlight.
1. Plumbing completed on one outdoor NFT system. Planted with kale and arugula.
2. Light fixture mounted and plumbing completed on indoor coco drip system.
3. Possible evidence of bottom rot was discovered inside a tomato harvested from the indoor deep water system. This problem was discovered in March and was attributed to a calcium deficiency. A supplement was added to its standard nutrient regimen and the visible exterior discoloration of bottom rot did not appear in new tomatoes.
1. Manifolds for outdoor NFT painted.
2. Additional tower stands constructed and painted.
3. Outdoor trellis finished and painted.
4. Indoor coco drip system light mount constructed.
1. The NFT Beautification Initiative is well underway. All outdoor NFT racks have been primed and painted.
2. The swiss chard seedlings were too leggy to withstand the windy conditions on our rooftop. These failed seedlings, however, made a very successful micro green salad.
3. Kale seedlings are looking phenomenal!
We’ve been adding some new automation features for ourselves and our clients. This post will detail Lee’s experiences using the GroHaus system. We noticed that the system we used didn’t actually have a name, so we called ours Doris. Doris the Doser.
Doris is by far the simplest and most straightforward automation system that we’ve found so far. To set her up, we built our own custom cart, which was probably the most time consuming part of the process.
From there, it was just a question of running plumbing, calibrating the system, and setting our target EC and pH levels.
Plumbing was run between the nutrient pumps and our stock tanks of General Hydroponics nutrients (Flora Duo parts A and B, along with pH Down), between nutrient pumps and the reservoir, and between the reservoir and the sample pot for testing.
We installed Doris at our client Project FIND. Their systems are on a rooftop, so we needed to build a weatherproof enclosure to keep everything safe. We used a case that was originally designed to house outdoor computer systems, which has temperature sensors and cooling fans to keep the system at the right temperature in case of warm weather.
All in all, this was a great experience: learning new automation technologies, building custom houses for them, and using existing materials to amplify what we can do in different environments. If you have questions about automation, we’re always happy to help! Just email us.
We’re really excited for the return of our Five Gallon Bucket Workshop on Monday, October 13th. The workshop will run from 7 – 9 PM at our new space in Astoria. Come learn about the basics of hydroponics, and then get hands-on instruction to build your own drip system to take home!
We heard that some people have had an issue with the registration form. You can register by clicking this link. Drop ins also accepted — but remember, the cost of the class is $100 for people who pre-register, and $115 for drop ins. So registration makes sense!
See you on Monday.
