Hi, I’m here not long but I couldn’t find any good article about LED lamps, I know there are plenty of manufacturers who makes pretty good and cheap lamps like marshydro but I would love to make this topic as only the best LED lamps and not making price as a priority. The prority here should be making as many G’s as possible on 1mx1m growtent.
So I know two manufacturers who are very cool, both of them use 3W diods (which leads to smaller distance between lamp and plants which leads to bigger space to use and yields) also both of them doesn’t use any cooling system (all power is used to diods, no sound, no heat) and both declare that after 80.000h lamps works 10% less efficient which is a really good score.
Above manufacturers calls: sanlight, growspec
I was using until now sanlight M30 (30W) lamp with Royal Jack auto from RQS in 1 feet on 1 feet tent and the results are stunning! I’m making harvest after few days and on my eye I will have about 40g of dry herb after ~65 days moreover it is a very small plant (usually 40-60cm) which covered about 3/4 or 3/5 of the area. The lamp doesn’t emit any noise and the heat? well I can comfortably touch it during working hours so the growbox temp is the same as ambient ±0,5 degree and my monthly electricity bill was 1,8$ higher.
I used only soil with orgatrex nutrients from BioTabs every watering.
Another time (when my budget allows) I will test GrowSpec 60W cannabis version lamp and GrowSpec 150W lamp not only because of above features but I want to test individual light per plant in 1mx1m tent and also I want to push buttons on 150W lamp controller.
