Hi Guys and fellow growers
Ok , I have not long switched from HPS (sox) to LED lights , in my old set up I had 6 400W HPS in my number 2 bud room which is 10.5m square and in my number 1 room i which was 3.75m square I had 4 x 400W HPS
I have now changed over to LED in room 2 i have 1 x 450W 4 x 300w and 4 x 120w , the irst two are fan cooled . if you imagine a cross with the 450w in centre then the 300w making the cross then the 120w filling in the corners. I did it this way on advice from supplier to get the ideal light spread from the new lights
In bud room one its just two 450W lights simpler
Both rooms have intake and extraction fans 6inch intake and 1 4 inch for every 4 plants , there is also a large circulting fan in each along with a high level co2 slow release system. I have also got insect killers in each.
I grow in John Innes based compost in grow bags. I use a weekly pot ash based feed called chempack No 3 ( blue dissoluble feed)
I have moisture meters in 30% of plants and light meters and pH testers , all are good , room tempis a steady 75.9 degrees
Now my problems are these
slow bud development about 50% longer and worryingly the shading leaves at the base of the plant go brittle brown and then wither off,
I have also a problem now with black fly.
Now when i contacted the supplier of lights they said to try a full 24hrs cycle to hasten on growth , but this seems to only make the plants grow taller and not bud
I had very few probs with HPS just the normal deficiencies that could be sorted
The strains I am using are blue cheese , big bang and white skunk
