from time to time ive watered my plants with regular brown sugar as it feeds the microbes in the soil which helps the plants take up nutrients a bit quicker, but i only do this once every 6 weeks, it seems that molasses goes a bit further and feeds the plants and not just the soil microbes.
i do notice a difference in the plants when i use sugar but i think thats more to do with the microbes having a nice sugar rush every few weeks, so molasses clearly benefits the plants due to the plants using that the molasses provides,
here is the info on the sugar
Sugar is OK, but what you need is molasses! Sugar will feed the beneficial fungi and bacteria in your soil, which in turn help your plants absorb their nutrients. Molasses goes one step further- it provides minerals, too. You will want the darker kind of molasses, not the light. Darker means more good stuff in it. I use one tablespoon per gallon of water, deep into flowering I sometimes use 2. If your plant is a sativa (tall, with skinny leaves), it may not help- some of them just have fluffy buds. Try running a search on molasses here and you will start using it
so ill try and pick some molasses up the weekend and give it a try, ive read different guide some say use it through the whole grow, others say use it for the last few weeks of flower and another says use it as foliar feed.
reps for the info king, i think the warm water is the best option then add that to the cold water before watering the plants, its how i feed the sugar as adding brown unbleached sugar to water just dont make it disolve so i use a small cup and put a tea spoon of sugar in and add some warm water, then add that to the cold water, it does give my plants a small boost as i can notice the difference, not sure i would do it to often as it can encourage bugs and fungus but the odd dose now and again can help the microbes in the soil which in turn help the plants take in more nutrients,
here is the info below that i found

@dharma, if you cant keep the temps in check then try running the light at night and off in the middle of the day, that should help keep the temps down when the lights are on, my grow door has to stay open slightly to keep the temps in check, i can have the door shut for a couple of hours but any longer and the room gets toasty, so my lights come on at 11am so i am always up by then so by dinner time ive opened the door and the room is then left like that until the lights go off at 11pm, i try and set the timer to run at hours that are convenient to me, i dont want to be opening and closing the door at 6 or 7am when i may be a sleep then close that door at 7pm when i might be out, so i try and set the timer to run at times when i know im in and can open and close the door without worrying about not been their or been up to open it,
if the temps are to low the plants wont grow or they will grow but a lot slower, if the temps are to high then the plants will stretch as their trying to reach cooler air, which indoors its hotter the higher the plant gets, outdoors the plants stretch to grow taller than the surrounding plants so they can get into the breeze higher up allowing them to lose moisture and cool down, indoors they stretch into hotter air and this just keeps them stretching, if temps are to high in flower then the buds will also stretch,
so getting the temp in range really pays off, so as long as you got fans blowing over the canopy then the light can be lowered and the plants kept cool, in the winter i can have the light lower than 1ft but during summer months 1ft about canopy is about the closest i can get the light,
if some plant are not as tall as others then i use boxes to raise the pots up so the canopy is totally even then i know the plants are all getting the best light all the time
