REDwhtBlu, Bugs! , ever scope a floor,,, unless you're bleachN often id stay off the floor to reduce bugs. Many root type pathogens live on the floor. Dont share run off from bags either if poss. caster wheel system and Tanglefoot ( if you can tolerate the goo) under a set up like Kendo just posted is what I use. From here you'll have more control of root temps and and soil/medium pathogens .
Note casters, nothing on the ground , multi crops, and dont forget to look at these farmers threads on Bed Growing, badd ass . I'm going to do some small beds to start out with, with small plants soon. as you'll see in the next pics
Adding drainage and casters to your catchers will enable you to go Hydro, soil, beds or whatever your heart desire as you've added more control to your garden
While you're at the hardware store go by the lighting section and you can find this material. In the previous pic you'll have noticed Hydroton clay rock combinded with this material in the bottom of trays will improve the drainage and turns you tray into a hydro system instantly if choose that but I'd FULLY recommend that you go with bagged stuff for starters. Bleach this stuff often and dont let the plants smell to much of the bleach either. Always rinse the shit out of the bleach if plants contact that surface.
RedWhtblu, I'll be posting a thead that will have something "Ghetto Grow" in the title. ya might check it out if I post it cause I'm showing cheap as ways to grow bud as cheap as poss for new growers. and I'll be dumping some college hort notes to keep to ol skool growers interest and as always trying to create controversy to stimulate grow technique conversation in the mths or 2.
