Lighting revisited

Discussion in 'Indoor Marijuana Growing' started by MoW, Dec 8, 2002.

  1. From reading different things I am under the impression a good target of lighting is 30 watts per sq foot of planting area. And HPS is better for Flowering because of penetration of light thropught out the height of the plant. And the output of red spectrum.
    I have seen some plants that look very nice even though they were Flor CW throughout their growth cycle. They supposably would have been better if HPS were used in the flower segment.

    My question - I have some plants just about ready to go into flower. They are looking really good. Good stem growth, very bushy, nice color and looking promising.
    They were grown under Flor growlights at 60 Watts per sq foot.
    I fear they may go into shock with the change to HPS and
    am considering the proverb: If it an't broke don't fix it.
    AM I being overly concerned?

    Some ofthe added benifts I see usiung Florecents are they run cooler and that takes some of the problems assocated with heat - Burned plants, hot room to mention a couple.
    I have relied on what I have read here and from other people having much more experience then myself and may very well try some time in the future to use Flor's for Flowering bu this grow I am working on HAS to be a good one...I need the material out for private usage and don't want to be disapointed.
    The palm leafs I am getting fron cuttings and extar clone material is getting better and better and is at commerical grade now so I get confrimation I am going in the right direction.
     
  2. From everything i have ever learned hps is the best for flowering...hence the plant must like the red spectrum more than the blue when flowering....i don't think there would be a problem of shock....possibly more of a releif !!??.....Peace out...Sid

  9. These i moved in already and put tem on 12/12 yesterday they are 16" now. I didn't know better last time and I have next to it a plant thats at 60" now and still shooting it's been in flower for 2 weeks now.
    It's ok because I have 8 foot ceiling in this location if she wants to go that high.
    I noticed yet another in the veggy room that is about 10" with leafs about 6" lomg and 2 1/3 3 " wide.
    From the same kind of seed that the one pictured above is.

    I have been feeding them rain water and they seem to like it.
    Also made some compost tea for them and we had a tea party. I figure it should take care of any PH issues and feed them to their hearts content.
