This is very interesting foot print or diameter of the plant Again people are miss lead into thinking vertical has the advantage But your actually wrong ,,
now Lets take a average single 1000 watt Vertical and compare it to a single 1000 watt horizontal
your sweet spot it only the the size of the bulb you need to place plants around it so again single bare bulb problem is anything growing above the bulb is garbage any thing grown below the bulb is garbage, So with that said....
you really limited you self place small plants around that 1 k Wit non stop training or it will in deed be a mess ..
Comparing it to horizontal
See you are miss led into thinking that Vertical has the upper advantage this is not true one bit
so you think that cause you do not need a Hood that is the advantage ?? first off look at it this way a bare bulb hung vertical loses its intensity 360 degrees hence doing Donut vertical plants are suppose be the walls but your really only growing one side of a plant the ones closest to the light source ..
start a bon fire in a middle of a field get it going good now walk backwards from it 10 feet lets say wow did it ever get cold rather Fast and why ???
Cause all energy was shot out 360 degrees making it less intense ,, Hence you need no ducting to cool..
Now go into your house or start a fire , from wall fire place , or out side against a wall get it going good walk out 10 feet and what its still nice and warm meaning all energy is being directed on one direction and lets Face it more energy directed onto a canopy = faster growth and yield
Vertical growing is good with multiple lighting but going 1 vs 1 Vert vs horizontal Vert will lose how many plants can a person grow in a donut 1 light fixture compared to horizontal and most importantly is size of plants remember the size of the bulb and your sweet spot
for instance
Everyone tends to think you need no ducting for vertical hell same logic can apply or horizontal
Here was that 2000 watt grow i told you about 76 plants 5 week veg cropped etc
7 elbows dry umbrella parabolic open ended hoods fresh air in thermostatically controlled Exaust fan .. Turned on 2 - 3 times a night - 20 - 30 fresh air in thru warm up box
Room was 18 x 14 mylar covered roof side walls etc
Yes indoor can limit some on size of plant but again single vert bulb obviously donut only get you so many plants and of course your going to nee to work it and spend lots of time
next pics is again 2000 watt make shift room i think it was like 18 plants some extra's clones i had
open ended no fresh air in no exhaust nothing in the dead heat of summer vegged 2 weeks from 2" rooted clones cropped 2 times and flipped 5 gallon totes more or less went in there every 4 days to feed grow n walk away no need to baby sit i was enjoying fishing
You do not have that luxury with vertical it will punish you and yields will suffer
So really whats the advantage i see absolutely none .. Where a person has a guarntee Quality harvest with 0 larfy buds where Vertical tends to get where the plants light dead zones are
and on your Final thought mentioning only top plant only produces again this can be taken as a moot point again you only have that sweet spot in vertical where as horizontal pending on 600 - 1000 watt a big area of intense growth for instance the one plant in scrog
no matter what top buds are the money makers and the biggest buds like ones on 5 gallon pail Money shot
that one was 12 plant scrog 3 k just under 8 elbows and 3/4 pound of final trim hash
5.5 week veg
So For me i lowered plant count from 76 to 12 plants veg pretty muh same time only difference was more cropping and training to fill 75 Sq feet of canopy
