"I am going to use Expanded Shale. Found a place about 20 minutes away that sells it for $35/cu yd. Its going to cost me more to rent the dump truck than the media would cost. Still overall, even with the truck rental, the cost is under $200 for my…"
"Thanks Vlad, I am looking at the Apollo lights on Amazon. They take both 120 and 240.
I live in Ohio...doesn't get too hot here, how crazy do I need to get with exhausting the heat from the lights. In the winter I would want the heat in the…"
"No money crop here, other than my prize winning lettuce that I will grow :)
I may not install all the cooling to start, but at the same time while I am installing everything I would want to make electrical changes NOW while the studs are open.…"
"Chris, I don't know where you got your info but I would never invest that much money in equipment and pay continuously for all that power unless I was growing a money crop (marijuana) lol. You said you want to economically feed your family but…"
"Chris keep in mind when buying your ballasts, that using the controller you linked you will need ballasts that run on 240 volt (not the 120 volt).
I know it doesn't say on that web page you linked...but that Titan Helios 4 product is…"
"Ok, the answer I got for the lighting changes my whole design (at least for electrical and exhaust!). I will be running 3 600W over the GB and 3 400W over the DWC. I will also need to upgrade my exhaust to cool that many lights. Ugh. This gets more…"
Those types of controllers are nice items, but not a necessity. You can use standard type timers. Just off-set the timers (even by just a few minutes apart) so that they don't all kick on at the exact same time...meaning so that they…"
Generally, as a rule, with the fewer sources of light in a grow room, you end up with more shading issues. The extent of which, course depends on what it is you are growing. You're almost always better off with more fixtures/bulbs…"
"I am well within the "rule of thumb" I need 2400 watts for my sq footage. I guess my concern is physical spacing. Should I run 3 1000w lights down the middle like in the drawing below? Or 1 600W light above each bed?
"Usually a fixture will specify vegetative coverage and flowing coverage, so it will depend on what you are growing.. Coverage will also vary depending on the reflector used in the fixture. I would go with what the manufacturer states. Overall I have…"
"trees.. we are going to grow banana trees and who knows maybe a papaya or something? Mostly for long runs of tomatoes, cucumbers etc.. Don't want to block out too much of the sun. I thought about stacking DWC's, but that might block…"
