I have 2 Blackberry feminized , 3 Master Kush , 5 Ice , and 1 Watermelon Kush Feminized that have popped out of the soil. The babies that have been growing for 1 week seemed to have been over watered i think. Tempurature was 77 to 83 degrees at the tops of the seedlings (baby plants). with a humidity of 40%. I am usuing jiffy pucks to germinate then i transplanted them into red beer cups with fox farm ocean forest soil. I made sure to water the fox farms soil real well before i transplanted and i am still usuing distilled water. plan to start usuing ph'd tap water soon as they come out of this situation. here are 2 pics one of yesterday when they looked good and one of them today looking droopy. Does everyone agree that this just looks like i over watered a bit?

Stop watering them for a day or two and just mist them, humidity should be a bit higher than 40% at this stage, more like 50-70%

Well I already have the toilet bowl lid open and water in the sink and a humidifier to increase my humidity in this bathroom/grow room. Not much more i could do to raise humidity other then wait it out till it gets colder and i can turn my AC's off. Should be alot better during winter months...hot dry summers here , but it keeps me from ever having mold issues lol.

Nice, though you can always mist your plants
I recommend investing in a fine mist sprayer, you can use it to spray your babies with water or even for foliar feeding :)

Now i'm wondering if maybe it's just fresh air lacking. I didnt water since day before yesterday and soil is dry about 1 inch down. I wanted to experiment a little so i set a humidifier in the room on high last night and bumped the humidity up to 64% well i woke up this morning and they were twice as wilted first set of leaves even twisted around the stem some. So i turned off the humidifier and went to work. i came home and the plants were the same as when i left them. so i set 2 of the worst looking plants outside tonight for 2 hours about 2 hours before sunset. The ouside temp was 82 degrees and 35% humidity. (the same as the temp at tops of plants in the grow room they are in normally) Low and behold that was enough for the leaves to perk right up. I scratched my head a little wondering what could be different about outside vs. inside other then maybe fresh air?? I plan to set all 13 of my little gals outside in the early morning to see if they make the full recovery. think this could just be that i dont have enough fresh air in my basement? I run 1 window mount AC in the room right outside the bathroom (grow room with a toilet and sink)lol...keeps a stable temp outside bathroom at 76 degrees.

Normally you wouldn't want to water again until the dirt is dry almost all the way to the bottom.

OK now here is the deal...after bringing my plants inside last night and placing them under the lights while i slept this morning they were back to drooping and looking like shit. So back outside they go...they have been outside for about 2 hours now and have made a complete full recovery. I placed all 13 cups in a little box and set them out in my front yard along with my hygometer/thermometer. I was surprised to see the temps about 1 inch above the top of the cups to reach 126 degrees while in the shade the outside temp was only 85 degrees...i would have thought that 126 degrees at the plants would be way to hot. well i have been watching close cause i was worried that those high temps might make matters worse..i was wrong...things are looking 100% better. The only conclusion i can come up with is indoors my plants are not able to evaporate enough moisture thus giving me over watering symptoms. by placing them outside they evaporate water more quickly. I guess this makes sense. should i increase the temps inside my growroom so they match these high temps i'm getting from outside in the sun? the humidity levels outside vs inside are exactly the same. any help would be great.

your problem is the relationship between temp & humidity, they both must be dialed in for things to work properly

Nice to see a fellow colorado caregiver :) ..... So to correct this problem in my grow room what should i do? I have a high temp at the tops of plants of 83 degrees and 32% humidity and a low temp of 76 degrees and 29% humidity... Outside temps and humidity are almost the same other then in direct sun i am seeing outdoor temps of 95 to 120 degrees at tops of plants with 29% humidity...should i shut off my air conditioner in my growroom and let the temps get higher? with the AC off i will prolly see humidity at 35% and temps in the mid 90's.

this link is your friend, it is a heat index calculator
http://www.easysurf.cc/cnver16.htm

you want the heat index to always be a few points higher than the actual temp, for good, fast, stress free transporation

by example the numbers you gave of 83 with 32% would give a heat index of 81.4 and that is why your plants are drooping

you can play with the calc to figure out where they should be and change the element that is easier to control

So according to the calculator my ouside temps that are 85 degrees at the moment at the plants at a relative humidity level of 24% would be 82.2 degrees...and this is enough to change my plants from leaves drooping to the stem to reaching for the sky? .....let me talk just a moment about my lights to see if that is any issue. one 250watt Metal Halide 20 inches above plants, two 100 watt 6000k cfl's , and one 300 watt 2700k CFL. CFL's are 3 to 4 inches from plants...used these for veg before and never had an issue. the calculator was a cool tool but my data seems to be the same in both my grow room vs outdoor other then maybe un-natural vs natural.

difference outside is the sheer power of the sun, and the heat it puts off which is absorbed in the plant and soil, heat from indoor lights can not do that, the plant transpires to cool itself, just like us sweatin

heat and too much light on such small babies could cause that too i would think no? and of course air circulation is a huge factor keeping in hot stale air aint good

I'm sure the sun is prducing more light and heat then my lights indoors...but thinking riddleme is right it's a different kind of light and heat produced by the sun. and it causes the plants to transpire and in return they are loosing water wieght in the leaf and standing back up like they should. I'm just gonna take my 13 plants outside each day till they get a bigger root system and can handle a little more artificial enviroments. here is a pic of what they look like after spending most the morning and afternoon outside in a box.


This temp and humidity outside is working better for my plants then indoors with lower temps and higher humidity.. very odd

It is all about osmotic pressure, read this

I basically have over watered causing to much pressure inside the leaf vs the pressure from humidty inside my room. because the plant was over watered it was wanting very low humidity so it could transpire the excess and the rooms values wasn't letting it transpire enough..now that it has LO humidity and higher temps outdoors it's able to transpire the excess it has stored. makes perfect sense to me now.
