Putting cobs in parallels keeps the voltage the same. Just splits the amperage up. If you wired then in series then you would need a driver capable of producing the additive voltage of each cob in the string. as a simple example. If you have 5 cobs in series and each one requires 20V and 1amp...

Not bad. Shut down for the summer. Have a bunch of weed kind of hard to justify another crop at the minute. Also the room is getting torn down and I am gonna put up some Trusscore PVC panels for the wall covering before next crop. So gotta find the time to do that. But I think hopefully that's...

I would put money on a PH issue. Check Ph of run off and also of a slurry of the potting material. Whenever I get a similar issue PH is usually in the range of 4. Once PH returns to normal the new growth will look normal but those twisted crunchy feeling leaves will die off.

No i didnt. Maybe next crop.

I bought the extrusion from a sign shop. They are EX14 extrusions and EX12 extrusion. Used for making signs but they make great heatsinks. They were the cheapest thing I could find. About $15 for a 4" wide by 12ft long piece

Dude I just priced some evo 288 boards with sanan red/Uv/ir pretty attractive pricing. But also had the same concern about authenticity

If you have a volt meter see what the pins to the dimmer cable are seeing at full bright setting. I am willing to bet it's around 8V and what those wires need is 10V to give 100% brightness. Also depends on the driver too if you post what driver it is we can take a look. if you look at the UIS...

I can appreciate that as art all day

Have you tried getting some persimillis predator mites? I've tried every kind of predator nothing does the job like persimillis. Release 2000 of those fuckers once a week for infections and every other week for maintenance. If you get a bad infestation it's like herpes it almost always returns...

yes you always drill your own holes. Some trays have depressions around where they expect you to drill the holes though. But any tray can be a grow tray as you noted. Yes you raise one side of the tray and put the drain hole on that side I make it drain to a corner.

Damn sabres breakfast got me hungry

Based on the lighting the two mini splits are not enough. Your lights will create 32000BTU of heat but you have only 30,000btu of cooling. And this isn't taking into account heat from fans, dehumidifiers everything else in the room. Also you don't need as much space to veg as you do to flower...

I lived in northern Manitoba for a year I'll never forget there was a day in March that was zero degrees and everyone was out in t shirts like finally summer lol.

Savanna

Cool idea to make new rails and use those. But that would force you to have to recreate all the internal wiring in the bars. I think you had the right idea with cutting the ends off. A machine shop could do the whole job in under an hour for sure (at least I know I could). Little bead of...

Kind of like responding to a thread before reading it isn't it? ;);)

Some drivers have AUX 12V to run stuff like 12v fans for cooling or other auxiliary purposes lol. Usually it's prettt low power something like 0.5-1a

Not a dumb question at all. I believe the owner wanted to be able to fairly easily convert back to a normal shed space if need be. That being said there is no drywall in any of the grow spaces. Only PVC panels. So the building was spray foamed and then covered up with 1/8" PVC panels. So no...

AC infinity fans use 0-10v dimming signal same as the drivers. Depending on the driver it could be pwm dimmable as well.
