My (not so small) grow box WIP

I framed it, put top on, bottom on, one side and 4 rubber caster wheel.

The half sheet of plywood is only there for stabilization when I have to flip it on its sides.

 

Haven't drilled the inlets yet, just finished the box. Will do ventilation before mylar goes in.

 

Yup. 100 and something sqft of mylar.

 

Wiring up sensors, relays and lights.

 

I still need to frame up a proper door instead of 2 pieces of plywood with a random a assortment of different and some too small hinges.

The top and bottom meters have built in 12v relays that are triggered @ a specified temp. So I can use one to trigger something if the temp is too high and one of the temp is too low.

 

So glad I buy heat-shrink tube and crimp connectors from China.
4$ worth from China would cost me like 50$ if I bought locally.

 

Almost ready!

 

Works good so far. Think the box will actually be able to keep the room at a nice temp during winter, but next summer I will have to build some kind of swamp cooler or something.

 

My only issue now, is knowing when to transplant. The last time I did it, there wasn't enough roots and I basically wound up planting roots and sweeping up dirt. lol
