i have grown for a few years now, ive tried the mh/hps combo, also cfl in micro grows, ive wanted to try leds for a long time but they were just too expensive.
not that long ago galaxyhydro, also called roleadro released led panels that looked ok and had decent reviews and since they were cheap i decided to give them a try.
==============================================================================
grow room (very small)
- 70x40x200 cm
- 1 dinachem from dinafem
- dwc bucket with 220 L/H air pump, dual output
- plagron hydro nutrient line i used GH flora series for the first 2 weeks.
- small carbon filter and extractor
conditions :
- temperature : 22-28 celsius
- 12/12 lighting schedule after 10 days of grow , cut after 70 days since first pistils showed up
- ec : 1.4 in grow 1.8 in flowering ( it was too high)
- ph 5.8-6.3
- solution changed every 7 days
============================================================================
before starting the grow journal i want to talk quickly about those leds.
the 400w cob performs well, growing stage was vigourus, maybe a little less compared to a 400w mh but it might be genetics of the plant, also the internodes stayed quite tight.
the lamp is quite noisy to my taste, way less than a normal sized extractor but i would say it is loud as a noisy computer ( fan noise)
luckily you can very easily open the panel and wire the fans in series instead of parallel, this way they run at 6v and are very silent.
it doesnt get too hot, and the build quality is really good for this price, really... if someone wants some pictures of the inside i might put them sometime.
the biggest upside of those lamps are of course heat, they produce a little, the 300w is like a 125w cfl in terms of heat and the 400w cob like a 200w cfl, so perfectly manageable.
125 grams, with less than 190w of power consumtion, and its easily possible to get better resuklts with a larger grow room ( mine is tiny) and LST, but i think its nice to see the result on a less than optimised plant...
i think the results will shut up more than a few idiots here saying chinese pannels are crap, i was really happy with this one
feel free to ask any questions, the pictures in the end are whiter because i found out how to change the settings to get them to look less purple/ pink, which i didnt know how to do in the beginning
since some people here ddint know that imaging softwares exist i posted a gif to show the settings i used to make the light appear more natural, i kept the the first pictures from the post original so you can see the natural color of the lamp
