Yes, that is the plan. Just a plant or two and the rest empty. No water for transport and carrying. I thought I'd put the plant pots in a container to transport, take the empty hydro unit in and then re-setup. Good point about the water temp - been there and done that with transplants. Amazing how fast a transplanted seedling will die when given cold water. I'll bring some clay pellets to display (in a bag). Logistics will take lomger than the presentation! The meeting is being held at the local library (of course) down a set of steps.
I'm going to take an empty ag plus one (minus base). Demonstrate operation and then put plant on ag to show.
Thanks you for the help!!
I have been reading all this with interest. I think the clay pellets are there just to support the roots. You could use perlite or vermiculite although you would need to line the pots with nylon curtain like material to stop the small perlite from escaping..
As far as transporting is concerned providing the car journey is less that 45 min or so I think you could transport without water. When re-wattering try not to shock the plants with a very different water temperature. I think the clay pellets absorb water so the "dry" pot may be quite heavy. Try lifting a pot which has been sitting in the outer bath overnight with the maximum water level.
Perhaps you could try a couple of larger plants in two of the pots so that you could demonstrate the system with soil grown plants inserted as per the very inadequate instructions which came with your system.
Best of luck
PS Hengis - was great to hear from you again! Growing anything now?
Eek, yes, moving it will be a challenge. Good thing they're only seedlings you're moving - bearing plants would be a no-go.
Wow, I'd no idea the pots were so big on Emily's Garden. The pix I've seen of them, it looked like it was sized to grow 6 African violets or pansies or something. 9"x6.25" is big enough to grow some serious crops! And 5 gallons enough to water them without the solution going presto-toxic. I kinda suspect that's what happens when trying to grow big plants in the AG - .8 gallons is nothing to an adult cucumber or tomato plant. The nutrient balance is probably severely skewed (and for me, usually the pH) within a few days.
Thanks for the link - confirms that a capillary mat or something needs to be included to bridge the gap between either rockwool cube or ag sponge. The pots are 6.25" square by 9" deep (huge to my eyes!). I filled it with 5 gallons of water and it looks good to me - no bowing of the sides and what I'd expect from a DWC setup. I am now really behind on starting seeds of something to show at the demonstration! Why did I volunteer to do this? The main challenge is transport. Can't easily lift 40 bs of water! Will need to be emptied to take in the car.
I'm really looking forward to testing out this hydro unit. Looks like the capacity is just right for a starter unit! Full size peepers next fall!
Huh. Yeah, they just sort of tossed nutrient mats into the discussion halfway through, without ever describing how the silly things got installed, even if they did exist. I found this other instructions pdf for Em's Garden on the web, though - this one includes the mats:
I suspect even yarn loosely tied around the starter cubes, would work.
Looks like a very cool system. How big are the pots?
OK, I just realized the fill line is the minimum level - duh. I'm supposed to start out with 6 gallons of water. That makes more sense. I'll see how that works. I still think I'll need to use some capillary action with little seedlings...
Hi Peat and Gisette,
The instructions are very vague - one sentence about capillary mat and I can't find anything helpful on the web. There is a fill line on the side - I'll try adding water above the line to bring up the level (kinda afraid of the unit bulging!). I don't think it will come all the way up to the roots. Take a look at how high the pots are above the side. I'll need to experiment this weekend.
Here are the instructions:
There is another way, immerse the whole pot completely in the water if possible...
Not as drastic as it sounds, remember the 'lettuce raft' experiment, everything was completely soaked, the seeds never drowned because there was enough aeration from my air stones.
Only downside here is that the seeds you are growing could take exception to being saturated all the time, lettuce positively thrives in this environment.
