The Magnums have 60 degree lenses and are really designed to get penetration on bigger plants in my opinion. Scrog is designed to have a very flat canopy so needs a bigger footprint with less emphasis on penetration. I would go with two ISIS-FX1 as they run 90 degree lenses and I think are taylor made for that style of application. For some backup on my opinion check out the first grow run by LedBudGuy running ISIS-1's over very short plants. 764 grams from 5 ISIS-1 panels. I think they would be money for SCROGhey Dunit, do you think 1 ISIS-FX1 (170W) would produce some nice plants in a 4x4 area scrog? or would you recommend 1 magnum 357, 1 ISIS-FX2, or 2 ISIS-FX1?
I only like light movers when they are used over a very short distance to help avoid shading of lower branches, basically moving the light inside the normal coverage area of a single light. Anytime you use one over a large area to replace another light you basically reduce your intensity for the duration of the light cycle. Because LED's dont have the footprint of big HPS lights I'd be inclined to avoid light movers but thats just me.
Irish did well and was certainly one of the pioneers of LED growing and his journals convinced me to give them a try again after my Procyon experience. LedBudGuy is doing better and watching his grow, and using an ISIS for veg was how I decided to go with Magnum as they are made by the same company as ISIS. The Spectra series are definately one of the good lights out there and my only beef with them is that the numbers on their web page don't add up. They say they draw a certain wattage and they also post how many amps they draw at 110V and the two numbers aren't even close. For example the Spectra 300 claims to draw 360 watts but the amps x volts adds up to 264 watts which makes them very expensive for that sort of output. I'm sure you'd be happy with either and in the end ignore the marketing and see who's getting results. My preference is two magnums and I was going to cover a 4x6 area with mine but this strain just never got as big as I thought so I'm under a smaller area.
I think you should just believe resultsSo what do u think of the clame of totaly replacing a 1000w?
Put up some picsbeen watching your grow for a while. Sub'd
got two Skywalkers and three Northern Lights going under two of these panels right now. way taller than I wanted so see how they do cuz they are supposed to be the bomb for penetration
I have 12 in this current grow and 18 (purple kush) in veg under my ISIS. I'll have to look back in the post because I documented sise. I think I triggered them at about 17-18" and they are about 24" right now. I don't really have an issue with the height but was hoping for bushier plants and should have transplanted out of the one gallons into 3 gallons way earlier. I think the height is about ideal but if they were a bit bushier I would be happier.how many plants do you currently have in this grow? I know you started out with 50 but want to know what you currently have.
how tall were they when you switched from veg to flower? how tall are they currently now since they're matured? if you could have, would you have let them veg longer? if so, how tall would you let them go to before the switch? I'm asking these questions because I have a similar size grow room (4.5X5X7) and might how with mags because of this grow :]
I'll post some pics in a couple hours. Here's hoping. I'm pretty sure I'll get good results but maybe not the great results I was hoping for. Going back to PK for the next grow cause I know that strain well and what works for itno way. so was over doing the nutes? thats gutting man sorry to hear that. good luck hope you got it early enuff to still get some good results.
Hey Dunit,
Been following ur posts for a while now.
I'm going to be building perpetual aeroponics set-up. I'll be growing a crop of 24 plants per 3 week cycle I hope. I hope to have 3 tables(sections) full of aeroponics for the flowering room, and then another 30 plants veg per 3 weeks.
My measurements are 3ftx8ft, per section?so in total apx 10x8 when all 3 sections come together. I want to know if I can run 3 Mag's in an I-Beam(I) set up with 2x400's set up by the middle. Or should I be looking for a lower wattage, and place 2 lights per section?(6 total)
I'm hoping to cut 24 plants every 3 weeks. This would make a little more pricey light become a reasonable thing as long as the outcomes are worth it. Maybe I could even spring for 6-357's... then it would be 3ftx4ft coverage with some nice overlaps... Would it balance out in bud weight is what I want to find out from your totals at the end of dried grams per plant average... I know they are made for penetration, so I figure a close grow would work well...
I like the low heat factor an incredible amount, as police at my door generally makes a shitty day.
I figure I can comfortably run a perpetual system of total about 96 plants(72 flower n' apx 30 veg. - I'll not flower the six weakest looking plants...) in a 12x12 room, which means odor control is simple as I can run a negative air system where the carbon filter and fan are creating negative pressure in the chamber to make sure all smell disappears. This way no stinky gets out to make things all too sticky. I'm hoping the heat issue is the least of my worries.
Thoughts?
Tricky B.
I hope to keep the room in the mid-high 70's. I might want to just run the system off LED's. I was adding the 2 HID's for coverage, different spectrum, and also because I might struggle with the heating if the room is totally sealed from inflow and the LED's make no heat. Maybe a space heater can solve problems though??I like the sound of the setup and hoping to get a three part perpetual harvesting every month once I get dialed in. The only part of your system I'm not understanding is the lighting arrangement. You basically have three tables of 3x8 with one in first 3 weeks of flower, one in mid 3 weeks of flower and one in last 3 weeks of flower. You are talking about 3 magnums and 2x400HPS total over the entire 10x8 area?
What room temp you hoping to run and do you need the HPS for heat to maintain that?
