Sorry for going dark there. Lawn work over the past couple of days. Hopefully I can finish all that shit this afternoon.
… What is the floor space of your area? ...
I have a 2' (W) x 4' (L) x 5' (H) housing two ladies in 5 gallon Home Depot buckets. The ladies get woven until the 2' x 4' SCROG net is almost totally filled. Then flip ...
… Are you using HID or LED? …
LED - 2 Viparspectra DS600 Dimmable - almost 290 wall watts each fixture.
… What is your total height that you can actually grow? …
The SCROG net is about 21" above the bottom of the tent floor. 5" at the top of the tent is lost to the light fixture height ( a smidge > 3" ) and hanging hardware. I like to keep the light about 14" above the canopy - any closer tends to yellow some leaves so there appears to be some IR burn if they are any closer than 14".
All boiled down - I've got 20" of actual plant growth space. And since I flip when the plants are at the level of the net, that 20" is entirely for the flower stretch.
The photoperiod strains I have on the grow now stretch about 18" (Red Diesel) and 20" (Blue Cheese). I picked these strains to match my environment since flower stretch was a big factor. The lights are slowly raised during the stretch so that by the time I am at the 4th week of flower, the lights are at the top of the tent and I have my 14" between plant canopy and lights.
The carbon filer and extraction fan outside the tent to help maximize all available grow space.
