biosphere mini updates: it's mini and we're building it! [updates]
Yessss so I got approval to make not one large biosphere but two small ones. So they'll have roughly the same design as the other biosphere but they will only have a 3'x3' base and stand 3' high. And we're making two of them! This also means we can make them nicer and embed smart electronics in them. Here are the materials we need:
(14x) 2x2x8 pressure treated lumber: https://www.homedepot.com/p/WeatherShield-2-in-x-2-in-x-8-ft-1-Pressure-Treated-Lumber-302477/100023713
(1x) 4x8 plywood: https://www.homedepot.com/p/1-2-4-ft-x-8-ft-Oriented-Strand-Board-660663/100072564?MERCH=REC-_-rv_nav_plp_rr-_-100023465;302172512;304819679;206883043;308158312;100386717;311547609;204757739;313097593;204757741;300194383;100072830;308688495;310362152;206876429;310806354;310226407;308494611;310030855;310239125;313411098;310367115;202089083;308688414;-_-100072564-_-N
(1x) Roll of Plastic Sheet: https://www.homedepot.com/p/HDX-10-ft-x-25-ft-Clear-6-mil-Plastic-Sheeting-RSHD610-25C/204711657
(1x) Pack of Screws (10.0 lbs box): https://www.homedepot.com/p/Grip-Rite-3-in-Construction-Screw-10-lb-Box-3GCS10BK/204959302
***we can also buy twice that amount in wood if we really want to make two domes immediately.
And for the planter within itself (10x): https://www.homedepot.com/p/1-in-x-4-in-x-8-ft-Weathered-Barn-Wood-Gray-Pine-Trim-Board-243246/206748872
~84.8 --> OR IF WE USE NON-WEATHERED ~65.5
^or if we use 2x4 it's ~30.0
Then we need to add some hinges:
TOTAL FOR DOME: ~214.88 --> okay not the worst
AND WE NEED TO RENT A NAIL GUN!!!!
So tomorrow we're going to go to Home Depot and grab all this stuff. Then we'll work on building most of the dome through the weekend. We'll post step-by-step instructions here for the dome. We'll either build this or the big dome which we outlined in the last post.
