led/hps/dual spec/cfl grow. (what to use and when?)

  1. Hi.
    I am new here and cant find out how to start my own post any help would be grateful.


    Anyway my question is:

    I am growing in coco using canna a+b i also have pk13/14 and bloombastic.

    I have a 400w dual spec sunmaster
    70w hps son t 2000k
    2x photon 21x pro led with new x3 lens same as the new hydrogrow 21x pro
    1x 125w 2700k cfl
    2x 20w daylight cfl

    I am trying to grow the best crop possible but need to cut down electric because of costs and power company i know it takes a lot of power to look suspicious but i have a few fish tanks and these together use around 800w constantly so bit worried about adding the lights especialy as my tank lights are on 12/12 with timers. i have just completed a grow using just the 400w dual spec but for this next grow i would like to try and conserve power i was thinking of using the 2 led and 70w hps and maybee just using the 400w dual spec for a few weeks if i did this in which weeks would the dual spec 400w benefit them most?. I am not a complete beginner i have done a successful pc grow and also a 375w cfl grow and a 400w dual spec grow which have all gone suprisingly well. When answering just consider the photos as i will only be doing these autos then all photos from then on.

    this grow is allready started i have 4 seedlings 2x dinafem kush and cheese and 2x dinafem cheese autos for some quick bud. i plan on veging the photos whyle the autos finnish then flowering them. I have room to do this.

    any help would be much appreciated.

    I also planning on picking up black strap mollases superthrive and cal mag which i havent used before any point in these when using the nutes i already have? i was told cal-mag is essential in coco??? i understand bloombastic allready has molasses??? was recomended super thrive as a folia feed???
     
  2. The less light you use the less you will yield.. So to save a lot on power you will have to take it out of your harvest. 100Watts per plant will give you a good value.
     
  3. I understand that but what other options do I have with the lights available I dont want to use the 400w hid all way through. the leds I have are meant to be as strong as a 150w hps a piece they are 3 w leds with double lens.

    Once germed early veg with this

    2x 20w daylight cfl

    Veg with this

    400w dual spec sunmaster

    Bud with these

    70w hps son t 2000k or / and

    400w dual spec sunmaster or / and

    2x photon 21x pro led with new x3 lens same as the new hydrogrow 21x pro
     
  5. thanks for the reply for veg i ail be using 2x led plus the 70w hps my question was should i switch to 400w dual when flowering or can i carry on running 2x led and hps and only use the 400w dual for say a few weeks and if so what would be the weeks to use it to get most benefit i do understand lighting pretty well i just dont know the most crucial weeks of flowering as far as yield is concerned. I am guessing its not the last two as people switch to mh for this which i think my 70w hps and led would cover what would happen if i used these and just the 400w dual for flowering weeks 3-6?

    Sorry my question wasnt very clear.
     
  6. I would not trust the guy who told you this information. No free ride. Use less light you will yield less and take longer to harvest.

    I would use the 400 watt HID for the whole grow (it is what I use, see my harvest pictures) and use the other lights around the house or on the Christmas tree.

    My answer sucks, but it is the truth.
     
  7. Thanks. I understand most led are crap but these are pretty bright and are really hot when i put my hand underneath them they seems to be powerful and I cant stress how bright these are. Do you know any one who has used these?

  8. the reason for me asking this rather than just using the 400w all way through is when it is on and i am not at work i have tv on + sound system + 2x fish tank with coral and metal halides And 200w heaters for them and a 52" plasma which adds up to around 2300w constant power and if i have the conservatory heater on and washeer and dryer and dishwasher + my outside fridge and freezer its will be more like 5000-6000w constant draw i have only had the fishtanks a few month and did the 400w grow around the same time and my bill has nearly doubled. I am thinking about ditching a fish tank lol.
     
  9. I know this might not seem much electric to someone in us but in uk it is very high usage you could probably fill a house with plants and use about this much.
     
  10. Buds = Lumen = watts = Quids..better to sit down and budget all this out
     
  11. its only Percy but I do smoje a lot.
     
  12. Anyone else have any other ideas on this?
