Due to some issues from the greater powers, I had to lie low for a while, but I'm back. To cut straight to it: NFT, totally 6 sqm, i have recently started scrogging just because it's a lot easier for me to get better yields when i do so. maybe I haven't found the right sog strain, but I think it's more a skill I don't have (yet). My system was designed for about 9 plants per square metre, but i seem to be doing far better going for a longer time in the veg cabinet and 2 plants per sqm. Each row is 2.1m long and .9m wide (2sqm), lit by 2 air cooled 600w HPS. There are 3 such rows. Till 2 days ago, I had 5 x 600w HPS (Lumatek ballast + Philips Master Greenpower bulb) and one lonely 400w HPS lighting the 3 rows. Power bills due to air conditioner overload and the frequency of air conditioner maintenance required has made me consider and research LEDs. With help and guidance from many forums' members, here as well, I eventually created my first 2 prototypes. the first one is a 432w Cree CXB3590 fixture with 8 3000k COBs, each running at 50w, cooled by an individual heat sink, totally powered by 2 meanwell drivers. (The model number of the LEDs is : CXB3590-0000-000R0UBD30H) the second one is a 420w Bridgelux Vero29 fixture with 4 x Vero29 COBs, each running at 100w, cooled by an individual heat sink, with an individual driver per COB. (i'll fish out the model numbers) These two LED fixtures have replaced 2 of my 600w HPS fixtures. Let's see how they do. it's going to be interesting for sure. The ones in scrog atm are a nice amnesia phenotype, and the wonky middle row is my testing batch for Bodhi's Goji OG. There are a coupla' monsters in there. Best Vibes El Chupa
