You like my hydro set up?
Not to be rude but your "hydro setup" is going to kill your plant.
the water its sitting in has no oxygen.
Roots need oxygen.
Also roots dont like light so they wont grow in that cup.
Light kills roots.
Look into "hempy buckets" if you want a passive hydro setup, its easy with amazing results.
for a noob though i would just stick with soil.
And i would only do one plant at a time in your space.
Also those bulbs you have are the wrong colour spectrum, thats why your plants are stretching.
If i were you id do a tonn more research before you even try to grow the plant..
You need more light, space, you need nutes, a ph meter, bigger pots.
tell us more detail.
what soil are you using?
What kind of seeds are those?
what is your waters ph?
What nutes do you plan on using?
