if you're going to keep the lights up that high, have you thought about just turning them horizontally and using a reflector? You're losing alot of light as it is now. Plants look healthy either way though.
looks great. Although, you might want to flip sooner next time. They look too big for your plant centers. vert lights work better when they are in the center of the plant.. Plants seem really happy :)
whoa bro those bulbs aren't burning the plants in the middle? my shits would be cooked up like crazy if they were that close.
after many vert grows, these are my thoughts on bulb height. granted maybe from the camera angle they might seem irregularly high in comparison to the plants midsection, but its a cost/benefit with regards to which areas of the plant has the highest concentration of bud sites. when these plants were younger the bulbs were aligned with their midsection as typical of a vert setup. however when the plant grows taller than the bulb, and the light is now at the plants waist instead of its chest, if the bulbs are not adjusted to compensate, the entire top 1/3 of the plants loses a tremendous amount of direct light. this is the very reason DDs, in his last 4 plant room, added an AW over each plant. yes, for a vert grow, the ideal sitch would be a 1k over each plant in an AW, and 4 1k around it. that thread and jacks mention of doing vert with AW drove me to design such a room that can be seen in my coco trees thread. however that doesnt negate the fact that even then it might be neccesary to elevate the bulbs in order to stay in line with the plants chest. strain and trim technique dependent of course. also with verts i dont believe "lost" light is an appropriate term here, redirected or maybe some would say mis-adjusted, but not ever lost. so it boils down to which plart of the plants are you trying to maximize? when a plant is vegged in vert, the lower, older, branches development with intensive robustness.on my first of two yoyo install sessions with these girls, almost every lower branch was hanging sideways bc it was to heavy to stand up straight, but at the same to strong to break. these particular branches develop huge colas. so when the plants chest is taller than the plant, its a trade off of keeping the concentration of light on these branches, or try and even out the plant so that the tops can have some love too.
these were flipped at 4 weeks and are on 52" centers and were not trimmed or trained at all. i didnt have an issue with space in this room actually, i felt there was a nice balance of plant to light to wall spacing. at the end of the run each plant was just touching her neighbor. i have room to go longer with the spacing but not wider. maybe another 8" or so next time, idk.
every so often ill get a cooked fan leaf or something but nothing more. there was plenty of cooling and air movement not to mention a set of eyes on them every day with that being an item on the checklist of daily observations.
f@*ing $ sweet man! I have a question, how did you extend the plumbing to space for vert.?
this UC was a "boneless barebones" order so basically just the buckets and the epi. all pvc was custom cut by me with the entire setup off the top of my head.
