You're the one trying to put 3 plants in four square feet, so the answers you get are going to fit the problem you've presented. You need at least 7 of your 23 watt lights just to produce some pretty wispy nuggets, and a lot more light if you want dense Nuggs. Practically speaking, you need a...
You want as many lights as you can cool in your situation. If cooling weren't an issue then you'd want the equivalent of 17 of those bulbs to properly light that many plants with that square footage.
You can snake an exhaust line starting from the part of your attic with enough room to work in to the area where you've cut the hole. Use a string on a pole to get to your exhaust hole, then pull the string through the hole, attached to your ducting.
Got your pm - looks like you've already gotten good advice on the feeding. Don't have anything to add as my thing is more about the unique requirements of indoor grows and it looks like you've got your environment pretty well dialed in.
Ok, since you still seem to want to stand by this post, here are my specific responses.
not obvious at all and missed by many. Check out the co2 stickies on this site -for instance the calc your co2 in indoor growing forum and it references - *The air already has about 300 PPM so you only need...
please site the post number, I must have missed it. Or do you mean that rant after your double shift? Thought you weren't sticking with that.
and I subscribe to the notion of overwhelming force, especially in defense mechanisms.
first you say to move on, then you return to your nature and...
still waiting for your proof this experiment is "just another underwhelming exhibition of improperly researched and poorly put together information" your words, back them up.
sigh - I was not taught to turn the other cheek I was taught to break the hand raised against me.
I always urge newbies...
you can't point out what doesn't exist.
there was nothing in my upbringing - and no, i'm not a christian - that suggested I should treat anyone any differently than they treated me. So, you got exactly what you dished out as your introduction to me. Double shift or no you are who you are.
so...
Hey everyone, I leave for a couple of hours and all hell breaks loose. Thanks for all the support, here's my two cents.
since I am the only one in this discussion who actually gets paid to do experiments please forgive me if I take your uninformed opinions and file them accordingly. Perhaps...
if you vent continuously, even at the ceiling, it will draw out too much co2 to make enhancement useful. I've seen about a 200 ppm co2 differential between floor and ceiling in a room with three circulating fans.
hey, it's the spirit of UB back to haunt my threads. Why don't you just let the people who are actually trying to help people do their thing and you can get your ego stroked some other way? Your points are baseless, as usual, and don't take into account real world indoor growing conditions and...
Your dimensions are awfully small. Are you growing in a cabinet? That would be six ounces of water, so your whole fermentation set up would fit in a soda bottle.
Drying always causes shrinking, 75% shrinkage is not uncommon. They should re- moisten from inner moisture in the jar, if not, add something to the jar to increase humidity - wet paper towel, orange slices, etc.
Don't make something simple into something complicated - just eyeball about a third of the volume for perlite and go from there. The mix ratios of ingredients are not that precise anyway.
