hi all, me and the kids had a huge bit of luck today, i am the kind of person who never wins anything, for example a while back i went to the main super market by my moms and my bro and sis where with me, well we was in the que at the cig counter, my sister was first then my brother was behind me, we all bought the same scratch cards, my sister scratched hers off and won £50, but it had a featuer on it that said x2 so she ended up with £100, now usually with scratch cards you have 2 winners together, so if i win a £1 i then buy the one after it and win another pound or 2 at the most, anyways i scratched off my card and had nothing, then my brother scratched his off and won £75, so thats the kind of luck i have.
anyways ill tell the story after i replied to the comments above
@Skybound, that pic looks good to me, my hood is very light and the main wing parts are very flimsy and i can bend them with ease, but the wings are attatched to another piece of metal thats above the bulb but on top of the hood, its their so it holds the wing part on to the part that holds the bulb, it has 4 rivets in it 2 at either end, so where the holes need to go it is a bit thicker id say about twice as thick, not to thick to work with but thicker than the actual wings, moneys tight at the moment so cant afford to be a sealed hood, i dont like the cool tube type ones as they dont have big reflectors and would spread the light wider than i want it, what i do at the minute is when i raise or lower the light i gently bend the wings up or down so the spread of light stays within the plant area instead of shining on the walls, i think this is reflecting the most light back to the plants instead of it lighting up the wall,
anyways as money is tight im trying to come up with something that i can make that will allow me to seal the unit up, so id need something thats clear to run from one edge of the wing and then big enough to reach the end of the other wing, so ive got some glass from an old fishtank, its part of the cover for the tank and its only thin glass, so i can use that to seal the bulb in at either end, then the open ends would be 2 small slots at the end where the base of the bulb is and the other end is totally open, so id need to make it so i can have a fan at either end of the hood, the big open part i can easily seal and mount a fan but the other part will be needing more work, not impossible and pretty easy to do but would need to be done right,
now i need to know if its ok to enclose these batwing type hoods, i would have a fan at the end where the tip of the bulb is and this would be blowing air into the hood and across the bulb, at the other end where the bulb holder is id have a fan blowing the air out of the hood and into the grow space, id use ducting and have it running to the top of the grow space,
so making it is not going to be to hard, if i had the cash id try and find one i could buy, but i got thin sheets of tin and pieces of glass so i got all i need, but i need to know if its ok to use normal glass, will it affect the spectrum or will using regular clear glass be ok, also if its sealed i need to make sure its ok to seal this type of hood, if i wasnt using 2 x 12v fans then it would fry the bulb, but my fans are high performance and when i got the one running thats on the hood now its clearly pushing the hot air out as i can feel just hot air getting blown out by that fan,
so if anyone can help me i need to know this.
1, can i use regular glass to enclose the hood, its just clear thin glass about 2 or 3ml thick, will it affect the light spectrum,
2, is it ok to enclose the hood as long as i got both fans running, they move enough air so im thinking it will be ok, i would also cut holes in the top of the hood directly above the bulb so any heat can raise upwards as well a been sucked out the hood, we know heat rises and rises quick when hot so why on earth did they not cut vents into these hoods as it would make sense to do this, put it this way if i was making and selling hoods then my first thoughts would be temps and how to keep temps lower and away from the plants, so vents are pretty obvious and directly above the bulb you would not lose any light
@JamesTheGreen, thanks for the info, ill have a look now, what strains do you buy when you buy strains, also as we know each other in real life then its ok for me to give you seeds, we just cant discuss seeds and ask for seeds of people we dont actually know, so if your interested in trying some of my strains then ill sort some out and give them to you next time we meet, i could send a 100 or more if you like, like i said to the other growers i know, i cant guarantee results will blow you away but im more than happy with the results and not had any poor results, but you grow outdoors and in a different climate and mine are crossed indoors under light schedules, so im more than happy to give you some to sample, plus it gives me the chance to see how they would do outdoors,
maybe we could swap some seeds next time we meet
. the bb x nl was a new strain coming out, herbie was giving them away with his orders a while back and i had a good few of them, its a very nice strain, i might even have some left,
thanks chronic, back at ya mate
@GiGa, the heat sinks would remove the heat from the metal but the heat im wanting to remove is the heat pushed out by the bulb, at the moment my hood is open, the cool tubes i think have a small reflector so cant reflect as much light as i want, without the 1 12v fan running at the end of the hood i can only get my hood at 1ft from the tops of the plants, well its just over 1ft with no fan, with just the 1 fan running i can lower my hood by another 4 inches, the bulb seems to push the heat down but with the fan running it pulls the heat away from the bulb and out the side of the hood,
with the ballast i cant spill anything on mine as its below a metal shelf in the bottom of my grow space, all i want to do is mount a fan at one end to blow cool air in and blow the hot air out the vents, but im in no rush to do it and i wont be cutting more vents either, just adding a fan at one end to keep it cooler and hopefully prolong life.
@Fish, back at you my friend
my next post will be about the luck i had today
