Welcome my friends and fellow growers to the show! After an accidental, decent last grow, two plants,15+ zips, and decent quality, am back with my original plan for last fall. Will be doing a 5 plant vertical grow with coco, screens, and stacked 315 W CMH (3100 K) and drip irrigation. Grow area - 4x4x6’7” Gorilla tent Lights – 2 x Nanolux 315W CMH NA Screens - 21”x 40” Overall working height is 54” (137 cm) Pots– Two gallon Smart Pots Medium - Straight Coco Nutes – Canna Coco A&B, Rhizotonic, Cannazym, Boost and KoolBloom. Number of plants – 5 Strain – Barneys Farm G13 Haze (4), and Critical Kush (1) The grow: Seedlings should be replanted into the two gallon smart pots within a week, one of the G13's is behind by about 6 day or so. The drip irrigation is a 1/2" setup fed by a 3/4" line that originates in a separate room, from a 10 gal primary rez and a secondary 14 gal rez that recirculates the rez's and keep the primary filled. The manifold is 8 stations, but will plug 3 stations. It will have equal length 1/4" feed lines that I am considering attaching a 1/4" cross that will allow three lines to feed each plant. Each main feed line will have a quick disconnect so I can move the plants in and out of the tent as needed to work on them. Will post pics soon of this setup. I used one of the 315W last grow along with a 400W LED, both hung slightly tilted toward the two plants. Now this run will be the first time I have run 2 - 315's in a vert grow. I am truly impressed with the 315W for how it responded last grow. Both ballast are outside the tent, have plenty of air movement so I am not that concerned with heat issues, do have extra AC in the small room I am extracting air from, if needed. Here's a picture of the two fixtures w/o the bulbs. Will change the height of the lower light stand by removing pvc pipe and replacing with with longer pieces. I will accept comments, both positive and negative, and suggestion for all you very smart people, with more experience than I. GR I am linking this to my Journal.
