thanks. i have the monitor set at plant height and it never gets above 1500 ppm, so its not a local concentration problem. the generator is five feet above the plants and a fan keeps the co2 from settling in one place. let's see what things look like tomorrow.
here's the before co2 shot from yesterday:
same plants in far row - see how they look after 12 hours of co2 (1000pm - 1500ppm, temps 85f to 93f):
going to give them another day to recover, as suncoast suggested.
thanks, i'll give it a little time. welcome to riu and i'll get you started with plus rep.
moved the generator and improved ventilation before i tried this time. pics when room lights up.
i've used these with two liter soda bottles - http://www.uncommongoods.com/item/item.jsp?itemId=18961&utm_medium=shopping+sites&utm_source=froogle&utm_campaign=18961 - if you thoroughly water before using these then you plants can easily last longer than a week.
these are up to date pics of the mystery seed females that reacted badly to co2, before turning the co2 back on again:
and these are five unsexed carmelicious plants just added to flowering room with co2:
i moved the co2 generator up five feet to stop any possibly high local pockets of...
here's what the female plants look like now:
the middle plant and the one on the right have been topped and pruned, the plant on the left only topped
and here are the plants that were in veg when topped and pruned: the plant in the middle of the back row and the plant on the right of the...
go to the links in my signature below for some required reading before growing. after you've read you'll have lots of specific questions that we can help you with. also check out the stickies in each forum.
no, the light is absorbed by the green part of the plants, not the pistils. makes absolutely no difference if they happened to be covered by an adjacent leaf.
veg room with 600 watt mh for veg, extra 170 watts of 6700k cfl added occasionally, flower room with 600 watt hps, extra 170 watts 2500 cfl added occasionally. co2 generator and monitor/controller.
detail in journal entries under my pic.
here's the deal on light. people use watts as a short cut for the amount of light - but by doing so you are using a rough estimate because each light has a different lumen/watt ratio. so 250 watts of cfl is a lot less light than 250 watts of hps, for example. lumens isn't exactly equal to...
no one can answer the question as asked because there are too many variables, many that deal with how green a thumb you have. i can answer that an experience grower with your conditions could easily produce 3 to 4 ounces. be happy with an ounce or two on your first grow.
the pistils are at the end of the growth tip so technically there's nothing on top on them unless it's a leaf from another branch. so, no, you're not going to be touching any leaves.
let's see if i can get you started on the right road:
1. read, read, read. the three links in my signature below are worth going through as are some of the stickies in each forum. you'll have lots of specific questions once you've covered the basics.
2. you need more light to have a decent...
as often as you want
anytime after the fourth node/ as many as you can fit in before the end of flowering, although i and many others stop topping when the main stem starts growing pistils
it does increase it but lots of other things can help too.
600 watt mh for veg room and 600 watt hps in flowering room plus four 42 watt and four 26 watt cfl's of each spectrum that i throw in from time to time.
i was scared to death the first time i tried it but it was easy. if i remember correctly, i topped at the sixth node.
