In April I was watching as NASA presented to the world the first HD images from their Solar Dynamics Observatory module that they shot off towards the sun on February 11 of this year. The module is equipped to "see" the sun in all it's glory, capturing images from the complete electromagnetic spectrum. These images and the fact that people have been getting decent results with LED + Fluo got me thinking that the biggest trouble with LED was how specific their waves are. If the sun is sending all sorts of waves our way chances are plants probably need all of them to work correctly. Manufacturers even pride on how precise their LEDs are in nm, when in reality we probably don't even want to be so exact and have LEDs "bleed" into each others area of the spectrum to cover it all. So I'm giving LED a try behind a false wall in my office's closet. The space can't handle the heat of a 450 HPS for sure and even 250 might be too hot; plus the electrical bill can't all of a sudden jump in 700+ watts of power consumption (between HID, cooling, fans, Fluo for vegging, etc...) I'm building a rig with 292 watts of power that breaks down as follows: 1 x LED UFO = 90 watts www.LEDwholesalers.com - 90 WATTS LED Quad BAND UFO HYDROPONIC GROW LIGHT 90W 4 x LED Screw Ins 4x15 watts = 60 watts Still choosing them, will make final decision when the rest are assembled, don't know wether to get just Red or mixed, spot or flood, PAR38 or Mini Screw In??? 2 x FLUO Full Spectrum 2 x 45 watts = 90 watts Full Spectrum Light Bulbs from ALZO digital 2 x FLUO UVB 10.0 2 x 26 watts = 52 watts Exo Terra : Products : Compact Fluorescent Bulbs 2 x Timers 24 Hour Outdoor Timer HB31R | Intermatic, Inc. Materials for the array will cost somewhere in this range: LED UFO $175 LED Bulbs $120 ??? Full Spectrum CFL $30 UV CFL $30 Cords w/sockets $32 Cords w/reflectors $40 Plastic ties, chains, etc... $23 Cables $15 Timers $30 TOTAL: $495 The 9 lights were ordered from eBay to get rock bottom prices (4 are yet to be chosen though) The frame I built with some cheap square metal tubing with a coat of matte white heat resistant paint I had left over from painting a home made reflector for my mother box. 4 hooks with threaded ends with washers and nuts for the corners and 4 screws with washers and nuts for the cross beams. From the 4 hooks at the corners 4 chains going to 4 hooks in the ceiling, the height can be adjusted easily by going up or down the chain in 1" increments, takes 10 seconds. All the cables are gonna be held in place with plastic ties so they can be slid and the length adjusted at any time. The 90 watt UFO is going to a heavy duty 1800 watt Intermatic mechanical timer and the other 202 combined watts to another equal timer and heavy gauge cable is being used through out; it may be overkill but safety first, no sense in risking a fire. The walls are built out of Super Diamond Mylar stretched over PVC tubbing. The frames are 4 corners and 4 tubes with just a little glue. The Mylar is stretched over the frame with plastic ties in the corners and some tape over the sides. The idea is to grow 4 strains on a perpetual 10 week schedule; it will be 1 plant of each strain at a time so 4 plants in each crop. Durban Poison for a pure Sativa, Purple Skunk for a mixed strain good for all around smoking and entertaining friends, Red Cherry Berry for a late evening high CBD relaxant and anti inflammatory and a fourth strain yet to be defined. The Red Cherry and Purple will probably go 8 to 9 weeks under and the Durban Poison the full 10 weeks, clean up and accept 4 new clones from a mother and cloning box. The Durban already has 5 weeks of growing in my mother box, check it out here: http://forum.grasscity.com/indoor-grow-journals/607386-first-indoor-grow-durban-poison-under-led-fluo.html Purple seeds are in my drawer waiting for some space to clear in my box and the Red Cherry is yet to be ordered (I want the seeds really fresh for sprouting and there won't be space for 2 to 4 more months until I stabilize my Durban and Purple moms). Before putting the Durban in for flowering I will be running some trials for the LED with a batch of 8 bagseed that I have to screen for males and then try to re-veg 1 for the possible fourth mom. Have no idea what they are and if they are any good at all but it was some good stuff that provided them. According to UPS my UFO is being delivered today as well as the 45 watt fuos and the rig was left hanging in the closet yesterday waiting for them.
