Cool Notes from Underground - 250 watt scrog cabinet




I got a camera today

Its a canon a610, I paid $250. I decided on it after seeing the macros at https://www.imaging-resource.com/PRODS/A610/A610A.HTM . You should check out the test images on that site if you are shopping for a camera. So far I am pleased, I was able to get it to work under linux (after some hassle) and I think it takes a good macro shot.

This is a papaya bud cut a bit early and dried for a few days. That was my first try at a macro, I know you guys can help me improve on lighting and camera settings. I set the camera and the bud on a table, set the camera to a small aperature (high f-stop) and manual focus. Lighting was light from a window and a cfl lamp. If you have tips for taking macro shots, please share them with me

Where I am from you can only get mexican schwag, well you can get decent buds too but the price is way too high. Some schwag is OK, and more than worth the 40$ and ounce you pay, on the other hand some schwag SUCKS. I have only had good cannabis once before :sad: it was when I met a guy on the disc golf course who smoked some tasty buds with me. He actually knew what the strain was when I asked it was KC33 and Jack Herrer Luckily for me he sold me a quarter oz at a decent price. The sack didn't last very long but the memory of it haunted me for years while i smoked dirt schwag

I had been reading OG very religously since university a few years ago but never really had a chance to grow. About 5 months ago I realized that I had the resources, the time, and the space to actually make my dream of growing come true. So I got off my ass and found and old dresser, made many trips to home depot and lowes, and spent many hours in the garage with a saw and a measuring tape. I made one order from an online hydro store and one order to seedsboutique.

Here is what I ended up with.

Equipment:
converted dresser 18"x29"x48" LxWxH interior painted white
"270" watt hps agro bulb
cheapo sola 250 watt ballast
4" elicient centrifugal fan with speed control
Homemade cool hood
Homemade can style carbon filter 4" core 6" exterior 10" long




The light hood is made out of aluminum flashing and two panes of glass. The hood is prism shaped, this design allows light to shine out a full 180 degrees.

The carbon filter was made roughly according to directions by sunisshinging on OG. I saved alot of money by making parts out of coffee cans and plastic bottles instead of buying ducting parts. I hope to document my method, I am very proud of how it came together. But sadly I made it too small, at its current size it only holds about 1.75 liters of carbon. It worked fine until late flowering when it was over powered by my stinky strain, still the smell is only noticeable when the lights are on. I am going to make a new filter with a 10" exterior (popcorn tin) and a 6" inner core(big coffee can). The new one will hold 4 or five times more carbon than my current one.

Ventilation scheme: filtered passive intake > grow area > carbon filter > fan > hood > ballast box > exhaust. I am going to disconnect the ballast box from the ducting to improve airflow.


Technique: Dished scrog.

I have a screen which is dished in a near perfect half circle around the light. Light shines out of my hood 180 degrees and the half circle of screen catches it all. This is better than a flat scrog for a few reasons in my opinion. It gives you much more screen area to work with a flat screen in my space would be 3.6 square feet, with it dished there is 5.6 sq feet! But this design is really supposed to maximize light effeciency, theoretically all points on the screen should be getting the same amounf of light because the light radiates out of the bulb in a circle.

With a conventional reflector hood more than half of the light travels from the bulb, up to the reflector and back out through the glass, not very effecient. WIth my hood half of the light just goes straight from bulb, throough glass, and to the plant. In short, instead of using a reflector to bend the light to shine on a flat screen we bend the screen to soak up all the light from the bulb.

First grow: nirvana papaya

No major screw-ups

THough I should have vegged longer and stopped training earlier. Still I am happy with the yield

I am using cheap soil and perlite in a 50/50 mix and I am watering with GH hydro nutes in the Lucas formula.

4 NRS papaya from seed. Germed all 10 in a pack, 9 sprouted, 1 died before first leaves, 4 males, which leaves 4 females. all showed sex after about 30 days.

4 phenos,
2 with similar dense branching, less stretch, small, numerous buds. one "fruity" smell one "coconut" smell
1 more stretchy, big fat buds, lemony smell, this is the keeper IMO, it matured just a bit faster than the rest. early harvested tester buds had a good high.
1 least stretchy, less resin, slower maturation, didn't like my scrogging

vegged for 38 days.

flowered for 69 days










did i mention ITS TIME TO HARVEST!

stay tuned

Very very cool SCROG/Light arrangement you've got going, looks perfectly dialed in for each other!

I was literally up all night trimming. wow, now i understand how much work it is.

thanks for the kind words hgl

HeresTheDank, Its hard for me to estimate and I don't think I will have access to a scale anytime soon but I'd say about 120 grams. Someone speak up if that looks like more or less than that. I will believe whoever thinks it weighs the heaviest

Converting the dresser was fun. I solved the door problem by putting it on wheels and making the back detachable by unscrewing some bolts instead of making a hinged door.

NiteTiger, thanks. I will be following your threads

Here are the fruits of my labor











What do I do with the trim? I am thinking some sort of solvent extraction. Or is there a poor mans ice/bubble hash method?

Swerve, thanks I think you will pull off a decent harvest with your scrog too.

onthatlevel, I need suggestions about what to do with that. I don't know. my preference would be for some kind of mechanical trichome extraction, but making some kind of oil sounds good too.

I know there is quite a lot of trichs in the trim, but there isn't a whole bunch of trim overall.

should I dry it out in the cabinet? or do something else? what does everyone think?
