Not to make it even more complicated a process but what about a 2 1/8 or maybe even a 2 1/4 hole saw on the backside. It should be close enough to make a clean break in the hole but you'll end up with a lip for whatever the frontside was short on. I guess too late now :)

Yeah, I did pop out the first few but the bottoms looked like they broke off a bit 'funny' and un-even resulting in a wider diameter hole where the foam broke off... I guess that is what you are calling a 'bevel'... Standing there deciding whether or not to proceed that way, the thought occurred to me that that 'bevel' might help trap a little bit of air and help out, however minutely, with O2 near the roots...but I chalked that up to me trying to justify taking an easy way out, so I got to drilling out the other side...Damn, I probably could've saved myself some time. Hehe, I guess that's what happens when your 84 short of 'pro'
Drilling out the backside just entailed setting the drill to a lower speed at tapping and releasing the power button as I pressed down, the hole saw would bite into that last 1/8" or so and come to a stop.

WOW three different drills! I use a hole saw that is 1 7/8 deep so it stops just short of going through then simply pop the cuts into a bucket using my fingers. The result is a beveled bottom edge on the pop out. I also use the pop-outs inverted to blank out holes when needed to keep sunlight out of the water.

I agree it isn't normal, we are just made to believe it is. The more I come to understand everyone's place in this dangling carrot dictatorship the more I see how it is just a scheme to fuel a very small number of peoples caveman survival instincts of greed and power. Not that it is a "western world" problem. They just have been playing the most successful version of the game and convinced most everyone else to play along.
The whole state of the world economy and everything that backs/fuels it is so laughable, and depressing that I just don't want to know or care about it anymore. I would rather just not be part of the game anymore.
Technology can be quite useful though and since humans are social animals I will still have to interact with the game a little bit if everyone else around is playing it :)

Most of us are all really, just normal people...doing 'abnormal' things because somehow we've allowed our lives and our time here to be hi-jacked by a structure/system that serves to perpetuates our misery...As simple as it is, at the same time it is probably one of the hardest and/or scariest things...depending.
When I was about 10 years old, through a string of circumstances I got to be dead for a couple of minutes...and it really helped put into perspective what is/should be important to me and my time here, and what is just non-sense. Anyways, I'll shut up now...
Congrats on your decision BTW...make it count

Retiring from the world is a great plan in my opinion, or at least semi retirement. I think a lot of people as you have pointed out before are pretty unhappy with how things are for "normal" people. It's a simple solution more people should consider.
Sorry to contribute to the comment jacking. Back to my desk job punching keys and counting the days until I quit... in December :)

Chris, The center bit from the hole saw I have did not pass through the 2cm template I had (without fucking up the template that is)...hence the regular 5mm drill bit. And I wasn't about to pencil out 80 individual rafts hehe...
@ Bob Yeah, I spent a decent amount of my childhood in the US...I don't know about first language though...maybe.
Listing a couple of fancy sounding degrees or a string of even fancier sounding jobs isn't exactly what I'd call "getting personal". I've lived in many different countries, doing many different things and most of the things I've experienced things that I deem 'important', ones which made a significant impact on who I am, and how and why I operate, have little or absolutely nothing to do with job titles, or the little pieces of paper that have allowed me to hold such titles. (As impressive, or not, as those titles may sound). As far as I'm concerned, most of that has been just me whoring out my 'intellect'/abilities out to the highest bidder...And i don't wanna play anymore...
Much more personal was the exhibit of some of my art at a small gallery in Zwolle, Netherlands or the music I've written and recorded than the forensic engineering work I've done for say, US Steel Corp...
Sorry if this sounds all 'hoity-toity'...you asked a simple question...guess I'm in one of those moods...hope it doesn't seem like I'm going off on you or anything, because I'm really not
Yeah, it's pretty rural out here (not rural enough though as far as I'm concerned...as I'd pretty much like to 'retire from the world' and all)...There's a small town 20 minutes or so downhill from here and a big city like an hour or more away...
If you want...PM me with your 'regular' e-mail I can send you 4 or 5 of the latest fare from a recording project of mine...it'll be like a crash course in getting 'to know me better'. Though you very well might not like what you see...hehe

Why not pencil out the template and just do the two passes with the whole saw. The center bit from the hole saw in this case should pass all the way through, making the reverse pass line up just fine or was this not the case for your situation?
Doing a second pass vs having to dig the cutout from the hole saw each time is a really good tip and something many would overlook. Great tip. Thanks!

@Vlad -You speak English like it's your first language. Did you grow up here in the USA?
I'm also wondering what your education or career has been. I'm guessing you are more than a self taught bio chemist.
It looks like you are out in a very rural area. Are you close to a small town are there large cities near by? Sorry if this is too personal, but I'd like to know you better.

Don't mind at all...First off, I made a template out of cheap 2cm thick polystyrene foam. Building on the wisdom and experience of Peter Shaw and Chris Smith, I offset my pattern by 45 degrees relative to the foam board. You can fit 12% more holes using this off-set pattern (staggered) rather than doing the perpendicular rows (which is easier, but wastes space. Or, you can get a similar amount of holes using an offset, while still better utilize the empty space and spacing available between plants. Anyways...
I used a 5mm bit to mark the center holes on the 5cm board using the template as a guide. Then I used a Milwaukee brand 2" hole saw (with 6mm center bit) to almost drill out the holes from the one side. The hole saw is "short" by about 3-4 mm (about an 1/8"), so then I need to flip the board over and go at it from the other side to finish the job. This is much preferable to using a hole saw that will take care of the hole in one fell swoop...since it's then a major PITA (and takes way more time) to keep having to dig the cut-out cylinder out of the hole saw bit.
I used a cordless drill for the 'template center holes' and a stronger AC powered drill with the hole saw. The foam and hole saw ate up my crappy 18v batteries right quick...I could only do about 2-3 boards max, with a single battery with the hole saw...it seems to take a LOT more electromotive force to drill out a 2" hole than it does to do a 5mm one.
