The reason for the sudden break in my first growlog was that I commited just about every error you can make growing cannabis, including the greatest sin of all. causing pain and distrees to my girlfriend and her plant...hell hath no fury etc etc. 3 days after putting her perfectly healthy plant in with my LED and the lower leaves started turning yellow along with mine. My g/f is very old school and blamed the LED and I was in no position to deny the strong possibility. things were very strained for a week or so. but after After a long weekend in Athens and a week in the Gulf of Naples where I reacquainted myself with Moroccan hash the air of disdain had thawed considerably and i decided to restart.It was only when I saw my girlfriend watering her plants, that I realised where i had been going wrong, CHRONIC UNDERWATERING!!! I also had the LED on 24/7 which is not good. Thanks to Autoberry on this forum who provided a lot of useful information on using Quantum Bloom LED lamps. I have also consulted with Muddie (owner of Quantum Bloom who is available most of the time for any help you might need.)
my set-up has changed its still a 90x 90 x 180cm SJ grow tent with a 240w Quantum Bloom LED, but now with a 200w CFL (courtesy of a friend) and a 110w CFL hung lengthways. I have 1xWOS? Pakistan Ryder ( started in late May and spent its first 5-6 weeks eking out an existence on our balcony and inside against the window as the heavens poured rain in Biblical proportions) 3x auto-seeds Auto#1 (which went in on the 1st of July and were chosen because they are apparently idiot-proof to grow) and 2x WOS afghan kush ryder (planted out on the 7th of july once the Auto1s had started growing well)
the earliest photo shows one of the Autos after a week, the second shows the Pakistan Ryder on the day it entered my tent, looking thin and bedraggled. The third is a shot of my setup at the end of the second week with the Afghan Kushs just visible in the centre. The final picture shows the pakistan ryder after a spell under the lamps, it really filled out in just a week
how long have they been under led? how you getting on with your led? I got the same one as you about 2 months ago and it won't grow anything. I killed two lots of plants and nearly a third till i switched back to hps and they shot up a few days later? they went yellow in seedling stage exactly the same as yours no matter how far away I put the light? There's a whole website explaining that the owner of quantumledbloom is a fraud and he is not using the bridgelux chips and he's been ripping of the penetrators and telling ppl there the same but there all cheap components! I hope I havent been ripped let me know if your seeing any good growth with it and how your getting it! Lol. Also does your led seem to have loads of white LEDs in it and a few yellow looking ones they did not say the light had yellow on the site! I though yellow was basically useless for plant growth? Ime no expert but I am loosening confidence in my light by the day! Sorry about all the questions mate but this is annoying that I can't get it to work? I hope it's just me being stupid
