I mean i'm just gonna toss this picture i have of what was left of my last grow when i had around 500g left and clearly it doesn't jive with that 429 number posted above. View attachment 3953923

That looks more like it! Regular size jar fits about an oz in it in my experience too.

i just harvested a hps plant, got 430 grams wet, which is a little short of a Lb. i'll post in a few days what its lost, but what i'm expecting to get is 4 to 5 ounces once its all dried, or 110 -140 grams....

Just out of curiousity, what is the relevance of wet weight and why would one record that info?

to have a sneak preview of the dry yeild

Are 4 boards enough? I think so

do you think 4 boards will be enough to flower in a 4x4 tent? i was going to build an 800w cob but i think i'll grab some of these instead.

actually not a lot in normal circumstances. if you look back a few pages, there's a small argument going on about how much someone claims to have harvested, i was just trying to give a real time demonstration of how much weight a fresh plant loses as it dries
and it is a rough estimate of your final yield, i've found it to be pretty accurate most of the time, just divide by 4

Tryin to keep her as short as she can be. 26.1w system level with killawatt device. 1/2ft from top and she felt a little uncomfortable with the light so i had to raise it and sorta lst her. Just testing things and observing. Cover crop served too.

As soon as I can order a 2 board veg light I'll be moving the 4 board into the flower tent. Started prepping it, screen is in.

Slate 1 Single VS Slate 3 single
Slate - 1.2lbs
Slate 3 - 1lbs
Cooling performance almost Identical.

Slate 3 wont replace Slate 1. Although Slate 3 is thinner and lighter, the cost did not go down. Thinner extrusion = more scrap/defect rate


Slate 1 left, Slate 3 Right

@robincnn hey robin man sorry to bug you just a couple questions, couldn't figure out how to PM. will there be a slate2 triple board heatsink at all in the future? and i only really need 1 driver so I'm thinking i'll get 1 kit and 2 boards+heatsink separately, but I don't really understand the difference between the 2 types of boards or which would be best for my purposes (higher amp or higher voltage). thanks

Yes waiting of some final parts, screws, boards, reflectors. Should have a sale next weekend.
Slate 3 Triple Kits wont be available anytime soon. need to test some configs and find what driver/wattage suits best.

288 vs 304, just go with either depending on availability in desired Spectrum. 2 options are to give flexibility of driver opinions.

I add a lot of large angle aluminium to a double kit so I can mount the driver away from the heatsink, am I making it better or worse?

I am looking to maybe FAB up a hybrid light with a Flat slate .... Curious
