CFL Closet Growbox.

k, so i went ahead and did mine refinement to the CO2 bottle design, and it works a helluva a lot more consistently. you gotta use plastic wrap for this way though, i just used aluminum foil around the top to hold the plastic wrap in place. Anyways, what i did was cut a little strand of fabric and tie a knot in one end. i just threaded the fabric through the hole in the saran wrap and the rest is just the same. The fabric absorbs the vinegar and let's a little drop...drop down onto the baking soda. Mine releases a little faster than i'd like, but that can be easily remedied by just using thicker fabric. I'v got a pic down there so you can see the little knot of fabric on the inside. I've been thinking about the size thing too, if you wanted to use a bigger bottle (as i may do for reasons i'm about to explain) it wouldn't really increase the amount of CO2 released, since it's still mixing drop by drop, but it would release for a longer period of time.
So anyway, i just posted pics of what my plants look like, tomorrow, after they've had this CO2 treatment i'll post some more and you can judge for yourselves how much my little gadget helps.

edit: it also helps if you make the baking soda on the bottom into a little crater, that way as the level of vinegar in the bottom rises it mixes with the soda on the sides, getting you a more consistent reaction. ...i think, hahaha.

as pomised, pics of my plants progress after a day...ok, a few hours, with the CO2 treatment. i took the pics as close to the angle and distance of the comparison pics as i could, but i rotate the pots a lot so they may be facing a slightly different way, and one of the PS leaves seems to be pointing up for some reason... if you can't tell em apart by now; White Widow left, Power Skunk right

:thumbsup:

I like your CO2 gizmo. Pretty cool. I'm thinking of giving that a try myself.

How often do you plan on fertilizing when they get bigger? I usually do it with a weak solution once a week. I switched to a higher phosphorous content now that they started to flower. I have 2 girls, but these aren't indoor plants- what I mean is, I have them in pots, but I put them out during sunny days and bring them in at night, so the light they get is limited to sunny days, unfortunately. My next try will be strictly indoor, since the fall season is nearly upon us here.

I'll also go with a cfl set-up and I enjoy reading threads like yours for ideas and just to see how well you progress.

Best of luck and keep us posted!

I forgot to ask this. I see people writing LST, but I don't know what that stands for. I'm assuming it refers to either topping or tying down the plants? Can someone spell it out for me pls?


Thank you.

LST is for Low Stress Strainning, tying the plant down so it stay shorter, this is good for people with limited space.

Thanks for the definition, bud.

i actually had to start fertilizing them when they were really small. i dunno if i just have mutant plants or there's somethign terribly deficient abotu my filtered tap water, but yeah, they needed nutes WAAAAAAY earlier than they're supposed to. I was usign a really weak solution for the first week or so of that (check out page 3 to really see what i'm talking about) but now i'm using som more concentrated stuff and am using it for every other watering to see how that goes. i'll try and remember to post some pics tomorrow and show you all how it's going

so i had to go into my box for something anyway, and decided to snap some pics to post while i was in there. WW left, PS right

In only 8 days your plants have made tremendous progress. Must be those nutes and the C02 bottle. Very impressive!

Ahhh... glad to see they're looking much better!! Very nice.
