Spectrum king 400+ watt LED vs 600w HPS.

Discussion in 'Hydroponic Grow Journals' started by janemba, Mar 23, 2016.

  1. first day in new system.
    4x8 grow tent.
    flo n grow system, 8 buckets.
    600w MH/ 600w HPS and spectrum king 400w+ LED.
    transplanted larger plants on the MH side,
    and smaller plants on the led side.
    ebb and flow set for evey 12 hours.
    RX geen solutions nutrients, with botanicare additives.
    i chose RX green because i wanted to try a cheaper nutrient then house & garden (my normal nutrient line).
    after some deliberation i went with it.
    after the first nutrient mix i relised, i missed the additives of house & garden, so i researched.
    i decided to run with botanicare, because one, i love liquid karma, two i tried some free samples years ago with cn17
    and was not desipointed. so i picked which products suited my needs.
    RX- Grow, Bloom, and base
    botanicare- liquid karma, silica blast, sweet raw, vitamino, hydroplex.
    also some kelp.
    combined feeding charts, and will adjust as needed.
    thinking about adding a bloom booster...

    i went with the spectrum king after almost a year of reaserch.
    i wanted a fulspectrum light, with the intinsity of a HID.
    fiscaly it made since too.
    the spectrum king LED has 50,000 hours before replacement,
    a HPS needs to be replaced every 1-2 harvest.
    so if you replace a blub every 2 harvest, 4 weeks vegs 8 weeks flower,
    thats a new blub approx every 2300 hrs, so in 21-22 harvest you will have reached
    50,000. at $100 a bulb in 21 harvest that is $2100, $700 more then what i paid for the LED, and this doesn't include ballast, and hood

  4. Day 5 in new system, planted aprox 3 weeks after rooting.
    plants are growing fast, healthy.
    EC equilibrium is is close, plants are using a little more
    food then water.

    MH seems to be growing a little faster then the LED.

  5. day 7, the plants are responding great to the system and nutrients.
    plants have recovered from transplant stress, and starting good growth.

  6. forgot to mention the strain.
    cannalope haze, love this strain, i havent grown it since 2012.
  7. Rockwool is cleaner, hold moisture better. Also just what I prefer.
  8. Rock wool also isn't biodegradable and the stuff is nasty if you happen to inhale it.

  10. Last
    Expanded clay leaves residue in the resivore, also its not biodegradable either.
  11. Little bit, buckets are 4 gallons, and the net pots are 3 gallons, so there is a little root ball down there, they always Sat in the residual nutrient solution, at the bottom of the bucket. So I added air stones to each pot.

    Start of week 2 (day 14), the plants really started taking off.
    the plants in the pots are in soil, and my mothers. also i wanted to see the growth rate.

  16. So you're system is more like an rdwc opposed to flood drain? Quite envious of your set up everything is looking great

    nonfiction's multi-strain grow
  17. Kind of, the resivore fills the control bucket, which is piped to the rest of the buckets, but it fills for a set time, then drains, I have it fill for 30 mins, and drain every 4 hours. So it will fill and sit for 30 min, drain, and won't fill again till another 4 hours. 3 times per 12hr light cycle. Ebb n flow, recirc-dwc.
    It's a hybrid system for sure, I like it, the veg growth was great, right now I'm in the middle of week 7, the buds are looking nice, but not as full as I would like to see with this strain.
    when I build my next room I would like to do a side by side with an undercurrent system.
