    my top 1-2 inches is drying too quickly in my seedlings cos my light is drying it out. I can't keep the soil moist , what shall I do? I need some heat from my light to support growth. everyone must have this problem

    not sure, maybe put alum. foil around the soil and around the plant
    it would help reflect the light to the undersides of the foliage too. then it wouldnt dry out

    tin foil isnt good for plants it causes hot spots . what kind of light. how old is the plant

    easy remidy is blanketing the soil with wood chips or somthing. anything that will sheild the soil from the light but will not restrict airflow to the roots. do not ever use tinfoil for anything other than wrapping leftovers from dinner or making a gravity bong

    why, i use alum foil as a reflector, and it works perfectly.... no hot spots?

    it just shrouds the lights... i mean if you have a huge crease in it, understandable..but if you crumble it into a ball and then outstretch it, there will be no over accumlated areas of light : )

    lol if you crumble it then stretch it out .. thats when it would create hot spots. flat white paint works better, and mylar works better than the paint

    Aluminum is one of the worst things to use for reflectiveness....NEVER use something that just throws the heat back at the p[lants, and also too can cause tiny hot spots that burn your plant like crazy...your better off to just paint the room white...it works WAY better.

    It is normal for the first 2" of soil to dry up...it is normal and there is nothing to worry about...the more the plant grows, the more it drinks, and you will have to water it more often...but don't overwater...buy a moisture meter...there cheap and effective...once the meter reads "3" then it's time to water.

    please dont question my knowledge on a topic that is widly known and has been prooven time and time again. tin foil sucks period. anyone who advises you to use it either A: hates you or B: has no idea what they are talking about... aluminum foil only reflects 70-75% of light, flat yellow paint reflcts more than that, also any crinkle in the foil (which foil crinkles alot) causes or may cause hot spots. foil also reflects and magnifies heat... what good can come of this????:confused:

    EXACTLY!!!!!!!!!!!!!!:hump:

    Actually i think it only reflects about 30% and absorbs 70% light, but then bounces it back as heat.

    im sure tinfoil reflects 70-75% of light, not so sure on how much is reflected/magnifed back as heat but it does reflect and magnify 4sho. either way there are far better options to get the job done serriosly flat yellow paint works better than foil (not that id ever use that either!!
