everything i have read says that having your roots exposed is bad. My understanding is that the light kills them. I could be wrong about what kills them but i know you dont want them exposed.

:peace:

I'm stoned as hell again, but I don't get this? You water 1 hr AFTER the light goes off to avoid evaporation? Is evaporation really a bigger problem than mold? Unless you are A) really good in the dark or B) using a feeding system, how are you not breaking the dark cycle by feeding in the dark?

You should water at the very beginning of the light cycle or when it's warm enough if you are in a cold winter month. I try not to water my plants until the temp of the water and the air are within 2 degrees.

If you are using soil pick up your pots when they are full of soil, but completely dry. That is what your pot weighs dry. When you pick up your pots and they almost feel that weight, it's time to water. You really want to let the soil dry out and you soak it again. This allows the roots to get oxygen and avoid root rot. Mixing perilite in your soil at 1/3 will help you avoid the overwatering problem by allowing that oxygen in.

Good luck, happy growing, and future smoke.
yeah pretty much how i been doing it..:hump:.

plus I just dumped 2 gallons of water into my plants that have 2 weeks left to flush out all the nutes, basically if you have a very well mixed soil you really shouldnt worry about overwatering I dun think
 
you must not have the baby in a big enough container it wont grow bigger until it gets good root growth throughout its growing area...after the roots are set it to where it can hold a large plant it will literally shoot up like its on steroids. good luck!!:weed:

hello my friend and i accidently ripped the plant out of the ground 3 weeks into flowring long story :sad:..
does anyone now how i can save it?? Does it still have roots attached? You might need to replant if not too damaged. Keep observing you should be able to see if its living or dying after a week or so.

OK ....so I went out to water my 3 plants today in the peak of the day... pretty much and my plants were looking very thirsty, much of all the leaves were pointing down and looking flacid but when I watered my 2 gallon pots with my Sparkelets bottle they perked back up alot am I still in the clear ? Im not whining or anything and not really freaking out, Im just seeing if anyone has had this happen and didn't have any reprocussions when it came to growth and progress or if they noticed problems what problems they had if any ?....any stories here or advice as to what my plant just went through with my misguided approach to gauging how 100* weather can dry up my pot so quickly..

I have read in several places including the cannabis grow guide that you should have the plants in light for 24 hours a day during the first 4 weeks. Is this true? if not and I have had my new plants (really my first time trying to grow) on a 24 hour light supply for the last 2 weeks. Should I change this to a 18/6 or leave it as is as it has been this way for the last 2 weeks. I do not want to stress the plants as I have heard that this can happen when you change light cycle. (my luck I'd end up with all males!)

Thank you

some people say 24/0 for fast growth. some people say and its some what supported that 18/6 give the plant a chance to rest and tend to make more females when starting from seed.me personally i use 18/6 for veging and seedlings. that's the way they grow outside naturally, so thats the way i treat them inside. i do see growth from allowing them 6hrs of night. but to each his own.

i have also heard that. roots are very fragile and anything from too much light exposure to clumsy hands can damage and kill the tiny hairs that are on the roots

The dark cycle is important for plants as they mature, it is the only time certain chemicals are active in the plants. I just learned that in BIO... College has it's perks
 
my seeds are germinated and the roots are growing and I've had them under the lights for two days now. I guess i'll be able ot let you guys know if my lights destroyed em or not soon. How long does it take before the plant emerges from the seed and starts to push through the soil?
 
I have 4 in. pot mg soil transplanted into fox farm 3 & 5 gallon pots two days ago. seedlings are 14 days old. some looking good but some suffering from burn or lock out from mg soil & high ph. I couldn't fill the pots all the way to the top with fox farm because I ran out, but got more now can I top off the others that are half way or at least to the first node of the plant with out hurting the stem?

Stress in marijuana plantsis caused by imbalances of the plant chemistry. Generally plant stress disrupts the normal chemical reactions happening within the plant and causes ethylene ( the aging hormone) to start developing in the cells.

A plant likes to have an average day with no surprises on any day of its life. Any unusual event in the marijuana plantslife will change its internal chemistry and result to slow growth. Some of the stress causes are

1) WATER STRESS: There is a lack of water or too much water for the plant to absorb. Water stress in marijuana plantscauses abscisic acid to build up and closes down the stomata.

2) NUTRIENT STRESS: Usually cased by too much, not enough, or an imbalance of the nutrients. This can attract diseases or nematodes (type of worm) and disrupt root function.

3) Mineral Stress: It is caused by mineral imbalance in plant tissues, usually due to nutrient problems or by adding to re-circulating mixes. This causes plant growth to slow. By the time the results are visible, the problem is already very advanced. It usually takes a week or so to recover from mineral stress.

4) PH STRESS: The PH of the nutrient solution is changing all the time as the plant uses the minerals in the surrounding nutrients and as the water is transpired by the leaves and evaporates from the nutrient solution. Wildly fluctuating PH will reduce the marijuana plantsnutrient uptake and cause deficiencies

5) AGE STRESS: AS a plant gets older, its nutrients need to change. A tissue analysis will show the plant using totally different quantities of each nutrient as it ages. In highly supercharged garden systems, the nutrient fed to marijuana plantsis different for each week of growth. Mature or ageing marijuana plantsneed far less nutrients.

6) IRREGULAR LIGHT CYCLES: These will change the hormonal balance in marijuana plantsthat use the length of light and dark to tell when to flower.

7) PLANT DAMAGE: Any damage causes the plant to change its chemistry to repair the damaged are of the plant

8) ROOT DAMAGE: Either physical or chemical causes the plant to divert its chemistry to keep the roots advancing and creating new root hairs to absorb food. Roots can’t actually rebuild themselves when damaged; they just seal off the damaged section and move around it.

9) Environmental extremes / Diseases: The can cause a plant to age and flow prematurely, a female plant to produce viable seeds without being fertilized, or just cause poor growth.

Another article will be written that explains parasites and insects
What could be so hard about it, stick a seed in the ground and it grows. IDIOTS!!!

i also have the same question about the roots showing thur the bottom of the pot,
will this cause damage or just draw water from the bottom and the top
I'm using 15ltr pots (8) under two 600watt hps and the roots were like tentacles out the bottom in no time at all,....just means they're greedy, bitches,..f**k em.
