Been wonderin when yas were gonna take the plunge Bro.....and....Hey Freds, do you veg under horizontal or vertical? There's quite a varied thought process on this. I'm thinking horizontal for the first 2-4 weeks from cutting nice and tight under T5's, then switch to a donut style vertical veg area around a 600 or 1KW vertical MH for 4-6 weeks prior to putting into flower. Then ease them into full lighting on the 12/12.
Since yas`re in the attic of an uninsulated barn , it`d be best to build the walls outta 2 x 6`s , and ceilings framed @ 8' so yas can insulate the fuck outta everything for environmental control insurance during deep summer....
Rockwool slabs like I used before retirement are waaay dense with an awesome r-factor as well as excellent sound deadening applications.........but.......
They`re fuggin nasty.......Just gotta get past it for the ultimate goal.......Or yas can use Pink panther or the Johns-Manville white shit if sound`s not a problem , just insulate with extreme prejudice or it`ll come backta bite yas in the ass with high ass a/c/powerbills in the long run that eats into the bottom line..bet on it........now......
When I ran big plant rooms with Krusty buckets , I vegged with 400 watt MH horizontal un-cooled reflectors , and when I went increased plant numbers Heath told me about the 8 bulb 432 watt T-5 fixtures that could be all but dropped down on top of fully rooted pre-veggers ta stack nodes and build laterals........that said.......
I ALWAYS vegged Horizontal as stated above , so I could trim , prune , and shape each pick of the litter bitch into mini x-mas trees by the time I put em in the bloom rooms so they`d all grow similarly and create that perfect "sideways" canopy......and why ?........
If yas veg with vertical lights , plants react differently than under concentrated reflected light in that they grow sideways toward the lights and bush out waaaay more than necessary IME , but hey....
Some folks love the way vert vegged plants turn out before the flip......if ......they`ve got the room /footprint for each plant to make it through end of stretch without growin into each other and havin to be hacked back so they won`t compete for lumens and environment......so....
All depends on your wants and needs Bro......Me ?.......I say flip em and dip em fer mo crops per yr......The longer pot grows as it gets bigger , the more potential there is for airborn pathogens ta take hold and budrot/greymold/botyritis as well as powdery mildew and you WILL deal with em at some point or another without total environmental control...believe that.....anyways.....
I know you want bigger low plant numbers , so learn your strain and how to get rid of sucker branches as the main laterals form...There`s an art to growin big plants and it takes runs under yer belt.....just gotta learn each plants growth pattern so yas know what ta get rid of and what to leave for the greater good of bottomline yields.......anyways.....
Nuff outta me this day.......Kinda warm.....Gonna take the dawg and catch some fish fer supper.......Holler if I can help , and....... oh........
Whoever in the fuck it is that keeps following my posts around and leavin unhelpful ratings when all I do IS help , can put my shit on ignore and fuck off.....after all.....
You DO have that "ignore" option , so quit bein a lil bitch......aight ?....or.... come out in the open and confront me on even ground about what you disagree with .....
I assure yas everything I post is on a "been there and done that" situation from doin this shit way too many yrs to think about.......
Sorry Stealth....Rant`s over.....
Now get backta work...........
Peace.....Freds..........
