So, i’ve started to make a little greenhouse indoors for sowing seeds.
I built it out of “reclaimed” 2×4s that I had left from my basement reno (either framing jobs gone bad, or the studs were too warped for framing).
I also used 4ft by 2ft sheets of fibreboard from home depot, about $3 each.
I bought two ballasts at $35 each which hold 2 bulbs each, and have a shield thing to direct the light downwards, also came with chains to hang them and a pull chain to switch them on and off, pretty nice setups (thanks to Brad for the recommendation).
Outfitted them with 4 fluorescent 32watt t8 bulbs, 4ft each, “indoor aquarium and plant” type.
The seeds are put in plastic cups from the dollar store (my favorite place to shop) into which I drilled holes for drainage, and placed them on aluminum cookie sheets (also dollar store).
When it’s all set up I will have 144 cups growing, with the potential to add way more if I can figure out a better solution for the drainage trays.
Lights are on a timer set to 16 hours a day and are as close to the cups as possible, so when I get sprouts, they will be ready to go.
On the floor is a small porcelain heater, to add some heat to the shelves (they are toasty warm) and also it has a built in fan which will blow the hot air to the top shelf and also circulate the oxygen.
My questions to you guys are:
1) what to do with the back and sides, should I enclose them with more particle board to stop the heat and light escaping, or should I use a thick plastic, or some other material.
2) should I coat the back and sides with tin foil or some other reflective material.
3) what is the best way to retain moisture in a setup like this
4) any other general suggestions or ways of improving. open to anything!
