    Can i use Molasses in a hydro system? and much do i use? If it cant be done let me know. or is there something else that i can use?

    Don't pour molasses into your hydro system. You will end up clogging the pumps, lines, etc and causing a mess for yourself. Try finding Sucanat in it's powder form but I hear that can cause root rot in hydro. It's the raw sugar the plants need from the molasses but without the sticky mess. Might be able to get it at a health food store or all natural kind of deal but good luck I haven't ran into any yet but I'm in soil still and will cross that bridge when I get to it. Check this thread out. http://www.rollitup.org/harvesting-curing/115042-molasses-no-molasses-you-tell.html

    I was wondering the same thing and was really drawn to the idea of molasses so i added some to my res. after doing so, i would not recommend it. first, molasses has a big effect on ph. if you get the right amount in there and manage to balance the ph, it actually stabilized for me for a while, but the risks aren't worth it. if you have too strong a concentration or your ph gets out of whack, your res will get really funky really quickly. what i would actually recommend is getting a gal container and filling it with as much 1tbsp/1gal concentration as you'll need to semi-flush your plants by hand every once in a while. i think it is good during later flowering when nutrient uptake is critical. just my 2 cents

    Try Sweet by Botanicaire, or Carbo Load from Advanced Nutrients. You can use the Sweet (Citrus or Berry) while flushing and it makes your weed taste like fruit. It's basically a specifically derived compund of carbs and sugars for growing. Honestlyy I think it works better than molasses or sugar, just cost more.

    The active ingredient in sweet is cane sugar.

    I want pizza flavored buds.. Know any product that will do that??

    works great in recirculating hydro environments. plus its got epsom salt in it too... its great to use for all stages of growth. AND ITS ORGANIC (berry anyways)
    so what it costs $60 a gallon?
    I done a complete grow with & without, and I yeilded an addional 2oz from the 4x4/1k WITH sweet. thats a pretty good return on investment. not to mention the buds were a bit more resiny & tastier...

    SWEET is the poop

    you can go for the sweet rocks, or use honey solution as foliar spray, but try to avoid molasses (too much sucrose),try to avoid adding sugared solutions to the roots since the leaves have a greater intake of monosacharides
    personally i'd go for the sweet rocks in your case if you want to spare yourself from daily foliar spraying.

    I have been running a GH waterfarm with unsulphured molasses, no issues. I use one tsp per gallon and let it dilute, im also running a airstone in the reservoir.

    i tried molasses in my DWC and it pretty much almost killed my gro, had to take it out, i didnt know there was anything like that, that u could use in ur hydro system to help out like molasses would.

    It was a schedule with a range of different types of nuts including Tiger bloom, big bloom, diamond nector, dark energy, grow big, kool bloom, and GH flora system.

    just now finishing up with flushing now, well developed and very swollen colas. i was growing a hindu x skunk.
