I received an AeroGarden Harvest and a Salsa Garden seed kit as Christmas gifts.
I started the Salsa Garden and only now have I noticed that it is a 7-seed kit (2 tomatoes, 1 pepper and 4 spacers). Oops. Well one tomato pod is spaced properly, the other one has the pepper beside it. Spacers are at the front and in between one tomato and the pepper. Too late now, we'll see what they do anyway...
We have very hard water here, the hardest in the country, so I set myself up with two big jugs (the kind used in water coolers) of reverse osmosis water and a hand pump.
On day 4, I noticed one of the tomato seeds sitting on top of the peat plug was turning green and cracking.
On day 5, the first sprout started to appear from one of the tomato pods. Only two hours later I noticed another sprout appearing.
On day 6, the other tomato pod sprouted and again within a few hours a second sprout appeared there.
The most developed tomatoes started touching the clip-on transparent plastic dome on day 7. By day 8 they were touching both sides of the dome so I removed the dome. As soon as the dome was removed it was apparent that the tomatoes were starting to grow adult leaves.
The pepper still hasn't done anything as of day 8.
Next step: dig out my unused aquarium air pump and use it in the tank.
