cheers BB, yeah I had a quick look at your thread with stealthy, Im very jealous as Id love a cab like the one he made but being a lazy arse means I just went with a grow tent. Picked it up today, well excitedcant wait for your journal dude
What was the lot number of your kessils that were bad. I have two magentas, Jun 2010 lot, that I mix with a MH conversion bulb. The UL sticker on the back of my kessils say 32W...not the 35w as advertised. I've ordered two ISIS FX1 panels, and will combine them with two kessils, and a t5 panel in a 3x6 foot room with a 45 inch celling. I can't wait to see.
I already returned the defects. I'll email Kessil and see if they can get it to me I have an email in my outbox with the serial number, but I didn't get the lot number. I'll have to check the UL when my lights go on. I plan on picking up a couple of those ISIS FX1's. They look to be the best priced panel with a 3 year warranty on the market. I have the scratch for 1 so it'll be on the way shortly. The only downfall is they run it for 140 or 150 hours straight or something like that before it leaves the factory. That's 5 or 6 days.
do you know how big those ISIS is...they are claiming 30 squard feet
Nobody makes an LED single LED light that can flower more than maybe 9 square feet, 16 would be pushing it with waste around the edges. Most LEDs are only good for 2.5ft x2.5ft or less
Im not just looking for 240s, im also lookin for the 500s, so im curious on this dudes dad. interesting to say the least
1000w HPS has a claimed coverage area of 12' by 12'. Remember that general horticultural lighting, which is what most manufactureres claim to sell, is based on greenhouse applications. I bet you could easily grow 25 sq ft of lettuce under my ISIS
If it looks brighter to you that isn't actually a good thing. Our eyes are most sensitive to light in spectrums that are least sensitive to plants. Basically the Par curve is almost inverse of the visible light curve. My feeling on the two is that the Penetrator is putting more PAR light out and will be better for the plants.
Fuck me running....................... It's already been said that most of the current Blackstar growers in this thread are in the middle of a crop and havent grown from start to finish with them which will be the real test..... My next grow will be with 3 240w units in a 4x4 tent. 6 plants in 3 gallon smart/air pots (dont know which yet). I have a current crop under them for a bit of flower but honestly i got my panels like 3 weeks into flower so its not going to be completely accurate. But since you insist i just opened my tent and here are some early bud shots of what i have since you couldnt see the other bud shots i already posted often............... Also be gentle as this is the FIRST time I've even thought about growing at all. My buds are 4 weeks into flower starting today (Sunday).
thanks bro rep to you as well. I have grown TONS of other species of plants and vegies in my day but mj is a whole different ballgame and i love bringing my farming concepts over to the grow room. I trained these autoflowers who normally take 1/2 strength nutes from everyone i talk to and mine suck up 1.5 strength nutes EVERY feeding now. I just checked my pots and they are almost dry after a little under 3 days. It's a principle we used to use in the production of corn and honestly mj treats nutrient buildup just like corn does. It shows all the qualities that a good corn crop will thrive with. I am excited to include air pruning and some other surprises to my next grow.
im sorry but heatsinks are the least of my worries with my grow light. If you mount them to a piece of metal and draw air away from it then you will cool your led's. I used to put an aluminum plate on laser systems to cool them in a similar fashion to whats inside most of these grow lights. Large heatsinks shouldnt be needed unless your running stupid wattage out of one panel like an actual draw of anything less than 500 drawn watts is going to be overkill. and honestly if your running that much wattage per unit then you should look into better solutions then heat sinks. not to belittle your comment as i hate false advertising, just my .02 on bulky heatsinks
damn these people fast as hell they took apart a unit and tooka pic justfor him that doesnt look like a huge heatsink at all for 300w does that look right to you for a 300w panel supposedly same size as an old 120wim sorry but heatsinks are the least of my worries with my grow light.

that looks like plenty of heatsink to be honest. The whole unit is turned into a sink with that badboy. Again I'm not the guy thats big on these things because im a man of simplicity by design. The colt 1911 has 7 working parts while most other modern handguns have between 24-36 moving parts that can break. KISS (keep it simple stupid) is my moto and it has worked out so far.
so wat you think that panel will keep chiller than regular ones with just a flat plate and fans will that make it last longer
i say its overkill. It will last just as long as mine or any other unit that has fans and a piece of metal for the leds to be strapped to. Once again i feel that these finned heat sinks are a marketing gimic like switchable spectrums. Why would i want to switch lighting? To loose the full potential of my panel? No thanks. I got frostier buds off this strain than any journal ive looked at for it, and to be quite honest i made enough mistakes that I will put my success in the lighting(once it was proper). If i pull 2-3 zips off these 3 then this will have been a huge success. My next crop im setting the bar up to 8-10 zips but im also totally revamping my grow strategy. Between air pruning, a new nutrient schedule, more frequent waterings and some other surprises i think that with the 3 units that this is totally doable. Lets say my units only draw 140(which i know is not true) that would add up to over 400w of drawn power. At 10 zips thats .7g/w which i think is doable.
