Linda, what kind of light are you using? How far are the seeds from the light? Are you trying to start all the seeds indoors or are some planted outside?

Watering twice per day might be overkill. You should only water if the soil feels dry. I did have an issue with my grow light being too warm and drying out the soil. Better to under-water than to over-water. Over-watering can cause the seeds to rot.

Also, where are you located?

Zone 5B in Southern Ontario. I only water the Tomato Rockets twice a day. The rest I look for signs the soil is dry like a lighter colour, cracking in the soil and it feeling dry to the touch. The Tomato Rockets are kinda like a tape I guess. I have the plants that are sprouting a few inches from the lights, just regular house lights and SAD lamps I have on hand. I took one large oval bucket I got from the Dollarama and lined the inside with tin foil and have a wide lamp sitting on top of that. Most of those plants are doing well its just that some of my seeds (right beside ones that grew and are doing well) have not sprouted and they would have been watered at the same time as the ones around them. I'm starting the seeds inside and I created a shelter outside with plastic tarp over it to let them get some sun outside. I've been doing this for a week or more and the seedlings are doing well. It's just some trays that nothing is growing in. If nothing is growing I assume maybe they aren't ready yet but the ones side by side with healthy growing seedlings should have sprouted by now. I have kept records to track when I planted, when they sprouted, when to expect maturity, etc. So now I have some trays with some empty slots where I transplanted the seedlings to larger individual containers. This way I can put all the seedlings in the limited light I have and the ones that haven't germinated yet can stay warm but don't need the light.

I had a heating cube generating some warmth but the house usually is a bit cooler so I thought that might affect the full trays and delay their germination dates. Doing some reading on the different types of seeds I planted I see that I could do something differently for the spinach (I read you can germinate them in the fridge??) I'm treating them all the same so next year I'll pay more attention to what specifically helps encourage growth between the different types. I think I'm going to go with the belief that if it's neighbour sprouted and are growing true leaves and looking great then it's unlikely those will grow. It could be the seeds I got I picked them up from Canadian Tire and Dollarama and grocery stores around as I saw them for sale. With a somewhat successful garden this year I will feel better about spending more money at a local nursery or buying local online.

Fortunately I see I have spare seeds of most of what I grew and can pick up more if I want this weekend. I'll try direct seeding outside once the frost threat passes.

They are even bigger now! That photo is a week old. My corn is now nice long leaves :)

Your plants look very nice. My cucumbers sprouted then died. :( How do you know how deep to plant seeds?

applemum, your seed packet has all the seed depth and spacing info on it - usually on the back. I think cucumbers are typically planted at about 1"(2.5cm) deep.

Did you try growing your cucumbers indoors or outdoors?
