I can't seem to find any trays deeper than about 2.5". The roots on these plants are definitely longer that that. If / when these plants start producing runners, I'll probably cut them and transplant them and start growing them out. These plants are at least 3 years old, so they may not produce much more fruit. So I need to start some new plants soon. Starting from seeds takes like 2 years to produce fruit.
I agree but.... The light shown above cost about $15, PSU $40, ESP32 $15, and about $5 for mosfets.just a heads up for all the led growers out there the best high power are cree/vero/citizen led like the cree 3590,vero 29 gen 7 and citizen CLU 048
if you want to replace HPS lights this is the way to go and for mid-power, you want Samsung LM561C lights for anywho care there amazing at growing anything including weed.
I have built so many light setups I have lost count, be doing it for people for 5 years now. nothing against mars hydro but they really don't perform compared to real LEDs I had a friend's who had both and they really can't compete with Cree,Vero or citizen cob led's and the Samsung mid powers are amazing
a little sight that decent for both http://cobkits.com/
