Good to know...mrs Rottin' and i had crap luck with soil and cardboard starter sets last year indoors. Grow lights just came, and will be starting indoor stuff soon. Do the peat pellets come with cups or are they independent ?
Get the peat pellets with the plastic tray and dome cover they come in trays if 72 and come with some fertilizer and labels.
When your growing from seeds there are so many things you can do wrong to screw everything up and sometimes you can do everything right and still not have good results but that doesn't happen too often. It's all about noticing what's happening that your doing wrong and correct it. Here's some thing's I have learned that will greatly increase your results.
# 1 soak your seeds in a water filled cup for a day before you sow them. This will really shorten the germination time and Increae the sucesss rate that they germinate by softening the seeds up.
#2 plant them at the right depth! Most seeds need very little soil overtop of them but it will tell you on the packet. I just make an indent with a pencil and then scrape the soil back over top
#3 use a heating pad under your trays to get the soil temp up to 75degrees range. Air temp and soil temp are not the same thing. Bottom heat will drastically improve you sucesss and the heating pads really aren't that expensive.
#4 keep the dome on top of you trays until the seedlings pop out then take it off or move your pellets that have sprouted to a different uncovered tray. If you don't they may start to get mold growth and rot out and die.
#5 get the plants right up under the grow lights most are leds now and produce little to no heat so your not going to burn the seedlings. I try to keep them an inch away. This will make it so they don't get weak and leggy
#6 rotate the plants around under the lights if you notice them not growing straight up or see them getting leggy.
#7 don't over water them this is probably the biggest mistake made. And I am guilty of this one often. If you see the leaves getting yellow chances are you are over watering. There is a way to rescue the plants if you notice it early enough by mixing hydrogen peroxide into water and watering them with that. The extra oxegen gets Into the plants and can make them green again in a few days.
#8 if you see they just aren't really making any progress after getting there first set of real leaves or any time during growth they probably aren't getting the nutrients they need. You may notice they are getting purple stems. This can be fixed if caught early with little I'll effects by adding plant food. Just make sure your cutting significantly with water and not using the amount need for full size plants or you will kill them.
#9 you have to get them ready to go outside "hardening them off" you can run a fan on them. Swaying back and forth slightly will force them to thicken their stems to be able take the wind when they get outside. Also you should start Opening the window for a short amounts of time to get them use to the outside temps.
#10 grow lights should not be on 24/7 plants need a dark cycle inorder to grow correctly. Put them on a timer so they are only on between 15 and 18 hrs a day.
#11 this may be the hardest one to do. If you plant multiple seeds in each pod you need to thin them out eventually so they aren't over crowded. You will need to snip the inferior seedlings in each pod at the base with scissors and discard them. Leaving multiple sounds like a great idea an you would think you will produce more because of it but the plants won't grow as big or produce as much if they are over crowded
Just a few things to think about.. there are lots of other ways to mess it up also haha
