It's my first grow and I went with a Mars 300 LED, with 138 actual watts growing 4 plants all bag seed for my first grow (1 stunted, four just popped , maybe 5 if the last one pops,) in a 5.75'x4.5'x3' space I was thinking about ordering a mars 600 to go along side it, since they're the cheapest/best quality lights I can get where I am. Things I still need: Ph kit (on the way Probably a dehumidifier for when they get bigger Anything you guys can think of P.S. this is my first post (i think), sorry if this is the wrong place or format or whatever.
Also I'm using Promix (plus perlite) and fox farm trio for medium and nutes. Temps and humidity sit around 25 degrees Celsius, and 50-60% RH And the light is at 18" from top of the biggest one. about 24 or 26" from the seedlings
