The light spectrum cast by HPS lights- although wonderful for including flowering- consists mostly of orange-red tints. These tints induce more stretching between the internodes during vegetative growth. MH bulbs mimic the summer daylight using these lights alone during the vegetative cycle along with keeping lights as close as possible with ought burning ur plants should help u get the tightest interondal spacing and should help with the node stretching problem.
hope this helps!! good luck!
Indoor growing is a sped up grow.. and people can get nice yeilds and not have to wait the original time 6-9 months inside its now around 85 days.the spectrom your plant sees makes the bigest difrance, thats why some peps think there doing good using a hps for veging, just cos the plant grow's quick in veg dont mean it will have big bud's
That's why horti super hps kicks ass. Enhanced blue spectrum. I'm using 3 four ft 8 bulb t5s for veg. Internode spacing is tighter but I have to veg a lot longer to get the same yield. I'm going back to my 1000wt hps hortis. Not to mention they hate the transition from pussy t5 light to a real bulb.
Over the years I've found that temps and feeding have more effect on stretch than lighting. My little plants thanked my for years for giving them an intense light source. I've been growing way to long to ignore shit I've seen first hand for somebodys opinions to come into play. Sorry but my experience trump all others opinions. I'm a see for yourself type grower.
To properly make that comparison you would have to veg the same type plants with the only variable being the lighting. In one room you would have the plants under the 1k HPS, in the other room or run you would use the same amount of plants under 18.5 54w 4' T5 flouros. Lets just call it 20 for easy of numbers and the added efficiency of the T5 HO lamps. That could be (2) 6 lamp fixtures providing a 4' x 4' pattern and the rest used for side lighting.... Veg a plant for six weeks under t5 and flower it then do the same with a 1000 at hps then tell me how great the t5s are. In my experience the hps smokes the flouros...
That's what I'm naturally wanting to think. But I have found that in addition to unknown and unstated variables, growers prejudices (whether known/admiited or not) also effect the opinions and information they provide. And obviously as a noob that is trying to learn I can't just argue something that my limited experiences essentially relegate to theory. But I'll take all the help/information I can get and consider everything before my decisions are made.hell yeah your high output lights will definitely kick some fluorescent ass
Thanks! That answer was way more objective and helpful. I have found that a lot of people here feel like they need to defend what they have said and get defensive and basically fight their point. This is the opposite and exactly the kind of info I look for, thanks again rep on the way.If it was a close comparison maybe. I wanted to replace the 1000wt hps I was vegging with for s couple reasons. I wanted to use my space more efficiently instead of circling plants around one light. I wanted more veg area and 8x6 of t5s seemed like the trick. They use 440 watts a piece so now I'm using more electric. My old man loves his t5s but uses ebb and grow and has never vegged under the 1000hps. The 1000 wt mh is s close second in overall speed and production in my experiences. It all depends on what your trying to accomplish.
