IndoorSalad Lettuce Splashers Test

Tags: 

This topic started mixed-in with a Kale grow comparing kale grown in Aerogarden, manual hydroponic "splasher", and soil. But, in the Indoor Salad book, one of my DIY projects is a splasher. So I started out just wanting to test the instructions for the DIY project, since it's been a while. Then I wanted to try out my new 1-part vegetative organic nutrients vs. one-part vegetative inorganic nutrients.



Then I decided I wanted to sell a kit for this DIY project, as a launch special to go with the book. Then I needed to select the product components and verify them and the instructions. And bonus seeds to go with the selected lettuce seeds...

Yeah, like that. It kind of snowballed.

Anyway, the first couple posts here are just copy-pasted from the kale growlog. Then further posts of tester salad's progress.

The next few weeks I was
The next few weeks I was rebuilding the IndoorSalad site. Haven't really changed any of my conclusions. I think the 3-cup and 2-cup (coffee can) splashers grow slightly better - it's hard to tell from the pictures, because they're also older - because the roots get more air. That's because they keep running out of liquid, and you need to top up all the time. Still think the quart size is the best trade-off. The kale are in half-gallon tubs - that's too big.
   
 
A bit closer on their current status:
  
Aside from the kale test (other topic), also trying to grow some mystic mix mimulus. Mimulus seeds are dust-mote sized, fortunately sold in pellet form. Anyway, it'll take another few weeks for those to reach any size, but they do flower quickly, and they like dim and damp. So should do fine in a splasher. The red sails lettuce is also a test - I've never grown a looseleaf lettuce in a splasher before. Seems to grow very well on the growstones. I've had problems with hydroton sucking lettuce leaves dry in the past. Of course, the air isn't dry in summer.

 
I'm getting tired of maintaining that many splashers. Two is fun. Twelve is a chore.

This array of plants is growing under two 6500K 23W CFL light bulbs, in hanging clamp lamp hoods. Like this (except the lights are much closer to the plants except when taking a portrait) :

On the lettuce splasher test:  so far the 1-part organic liquid Urban Farm Fertilizer Vegetable, and the 1-part dry GH MaxiGro, seem to be doing about the same, and the growstones and hydroton seem to grow about the same, too. Definitely think the 1-quart tubs are the best shape for growing 2 lettuce plants. But they're all adequate - the quart is just sturdier with a longer-lasting capacity, without the overkill of the half-gallon size tubs the kale is growing in.

Lettuce splashers - comparing UFF Vegetable vs Maxi-Gro, hydroton vs. growstones. So far, I'm thinking the lettuce splasher product for IndoorSalad will use growstones - made in the US of recycled glass. Nothing to choose between so far, on the UFF vs MaxiGro question - they may work equally well, with MaxiGro cheaper and easier to package, but UFF providing an organic option to those who'd prefer it.
