    What are peoples thoughts on the new led 3w chip grow lights,in relation to keeping light close to plants,stretch etc. Would you still need to keep light close to plants to maximize root growth,and to grow these buggers to around 2 to 3ft

    Would it be ok to use the correct blue spectrum with cfl for 12/12 veg pieriod, then when mature put under hps for flower.when put into flower do you still need to keep light as close as possible,as this is quite difficult for me due to heat.I have to keep hps around 18 to 20inch away.i understand the the reason for keeping light close to plants during the first 3 weeks + to promote root groth and tight internodes.

    You can start with a cfl i normally do if i can but only for a week. Other than that they end up alot smaller. I cant stress enough that you have 3-4 weeks to grow the biggest plant you can.
    Why do you have to keep the light so far away uying some fans would help, in my cooltubes my canopy sits 3" from the bulb
    Take it easy out there

    Thanks for the reply fella, so your saying from seed to harvest you your light sit 3inches from plants at all times .what do you think of this set up.

    3ftx6ft grow space... 2 rows of 10 6.5lt pots plan to have a foot spare to walk up and down the tent,if you see what i mean.
    12/12 of the so called veg peiroid useing two cool tubes with 2 250w mh bulbs.
    then when ready for flower 2 400w hps bulbs.

    well ill get this over with 1st, read the rules 10 plants. Yes many of us grow more but this is a percy site so we keep talk and pictures to under 10. Also its going to get very busy in that space with that many dide i do between 6-10 in my 1.5x1.2 space. Depending on the strain, what are you planting? any sativas will get too bushy and i wouldnt do more than 8, indicas you could do 18 but shhhh.

    ok so back on track, i can have my lights so closs as i use cooltubes, google them and i have a 6" rhino attached so it takess nearly all the heat away. But i still use the back of my hand as my gauge or just on hw the plants look generally, keep going lower inch at a time till them complaain then go back up then measure it and remember that distance. having a fan or 2 at canopy level is a must as well dude it will save you from bud rot, make stems stronger, move move air over the leaves, move the heeat between the bulb and the plants.
    Bulbs sound ok but i would switch lights after a week or 2 as the extra lumens outweight the spectrum. 66000 lumens vs 112000 no contest really.

    Any other questons dude
