So the lights arrived yesterday morning, just as I was jumping into a work meeting. The package stared at me from the corner of the room until the end of the work day. Pure torture!
I was too excited to cook a proper dinner, so pizza was the solution. 10 minutes later I began my feverish
mission of measuring and cutting and duct-taping and cable-tying. I had already planned out what I was going to do, but execution was really a thing in and of itself.
The actual cabinet is arriving in 2 weeks to a month, so the cardboard box will serve as an excellent platform on which to experiment. And it also means I can get started earlier!
After a very long day, I finished the first pass on my cardboard prototype!
I don't want to talk about the product/brand I'm using, also out of respect for this forum's policies. But I will mention the specs of what I'm working with. Each LED panel is 15W, with Samsung lm301bs, and can be adjusted for intensity. I'm using a lux meter to take measurements at different positions and with different light intensities. I'm aware that lux isn't PAR/PPFD, but for now all I need is an internally consistent measurement so I can make adjustments and try things out in a more systematic fashion. With the bottom light panels at 25% and the rest off, it's approximately "7000 lux" where the seedlings are in that photo. I started conditioning the seedlings today, and they were in there for 2 hours. I will progressively increase their time spent in the box each successive day, and the intensity of the lights too.
Probably the first thing you all will have noticed - it might be a little ambitious/aspirational, but I really want to try out vertical/side lighting to maximize surface area exposed to the lights. If the plants end up not liking it, I can always move the panels into a more typical arrangement. This one will require some interesting training.
Suffice to say there are still things I have to work on. Better cable management. I have an exhaust fan but no carbon filter yet. Have a bit of time to think about what to do in that context. It will be a tough challenge considering the spatial constraints. Perhaps I can have the filter on the outside? There's also better soundproofing to be done. I have a heat mat to go in there for the cold nights. No fan for internal air circulation yet.
The seedlings themselves seem really happy. The timing of the gear arriving really couldn't have been better - both seedlings have just sprung their first multi-tipped leaves. The days have also started to get really dark and miserable here.
I feel exhausted now. But all in all so pleased the journey's really started! Thank you to whoever's stuck around this long
