Cool Dan! Thanks for the starter phyto too, I've got a very similar set up to yours, though it's more ad hoc. It's two 2 litre coke bottles (like yours) that sits in front of a desk lamp which is fitted with a "curly" compact fluourescent bulb. It's on a timer that give it 16 hours of light, and 8 hours of darkness (according to Melev's website).
I only had small air pumps sitting around and had it on a "splitter" but something weird happened and one bottle wasn't getting any air, and there was a bunch of dead phyto or something on the bottom of that bottle, so I am using 2 air pumps now, one in each bottle. Just real simple airline from pump to the bottom of the bottle.
Any idea what species of phyto we are growing?
I'm really glad it works with RO water too (rather than salt water) as it makes it much easier to dose.
Mine don't seem nearly as densly green as yours does. How long have they been "brewing"?
What's your light cycle? And how much miracle-gro are you feeding them? I mix like about 1/4 teaspoon in RO water and split between the two bottles.
Thanks again for the starter stuff, I hope to get mine as nice and dense as yours! (Though I might need more lighting then, I suppose!)
What I'd actually like to do is some how set up a phyto station/shelf right behind my open backed canopy, which leaks MH light like crazy and see if I can get it to grow well there. I mean, it's wasted light, right?
