Well I do hope that I will get quite a bit more than the minimum for afs - 15g.. I'm staying positive but since it's a first grow I do consider small harvest a possibility.
Now there is one thing I ponder about - my box is supposed to have a max of 200-250 watts. Now that just sound silly, right? If the temp is fine and the leafs don't get burnt, then I don't see a problem to have as many watts as you like. So far I've got 410 watts and a minimum of 14 000 lumens.. Any ideas why they would give such a warning? Is there such a thing as too many watts when the other factors are in the norms? Or is it only for hps etc.?
ahhh, here I go, Ive been following the boards for a few weeks now and finally decided to register so I could contribute. Ive harvested several crops during my growing years about a decade ago, and recently started up again, currently have about 10 babies all under 4 weeks old. Im still gathering provisions and making my fixtures/boxes/ventillation etc but having fun remembering techniques I knew well years ago, and re-discovering the fine nuances of growing. Im currently in rockwool cubes in a homemade bubbler tray for seedling/initial veg stage, waiting until they're big enough to go into 3" rockwool cubes for main veg then into 3 gal homemade bubble buckets for flowering. For lighting, I started with a few 5000k 23w cfl's from homedepot because they were only abt $1.50 each, in a DIY 5 bulb reflector. After a few weeks (and another paycheck) I upgraded to the proper 6500k 26w cfl's and immediately noticed a more rapid growth rate. I have my babies under the homemade 5 bulb cfl hood until they outgrow that, then they go under a 4x48" t5 fixture (100$ on ebay). currently waiting with all 6500k bulbs but may swap in a 3000k to add a bit more spectral diversity. Then under a 400w HPS (or two, depending on how many females I end up with) with cfl's for spot lighting and a bit of 6500k during flowering to help with stretch. Currently using GH Floro series 3 part nutes with superthrive, B1 and Sweet Raw.
sorry for rambling but its my first post
just wanted to show that Im not a noob though lol. To answer your ? Dreambox... dont be too concerned with watts, ideally you should be using the least amt of watts necessary so you can to save money and decrease heat output. The goal should be to get as much usefull light as you can without wasting money and space on a ridiculous number of lights. I understand that space/financial/ventilation restraints can keep someone from chosing a HID light, but for 400 watts HPS you could get +55k lumens (4x the amount you have using cfl's), just putting that out there. But if your only option is CFL, then your logic is correct, except dont think of it as lots of watts on your plants, think of it as lots of light energy hitting the photo receptors on your leaves, that is then converted to growing energy for your babies. CFL's are good because you can hit your plants from all angles, leaving no dark shadowy areas to sit idle while the tops soak up the light. Using HID lights
it is possible to go overkill and saturate a plant to the point of overload, causing bleaching and excessive transpiration (they'll draw up and release too much water through evaporation through the leaves causing nutrient imbalances) Clf's however are not going to be intense enough to cause over-saturation. The only disadvantage to having a shit ton of small cfl's is that you're still causing 400 watts of heat that needs ventilation but only 1/4 the usable energy on the plants. You wont grow huge pringles can sized top cola's like HID's can, but you will have alot more undergrowth because you can get more light on the lower bud sights if used as side/spot lighting rather than HID's single point top lighting. You wont get near the total yield as you would with HPS, and it will be a bit less dense when all finished, but it wont affect potency. Potency or stony-ness is determined by the strain, you'll get just as high from a packed bowl of HID flowered buds as you will from CFL grown, but you'll end up with more total harvested using HID's
sry Im rambling again, post then smoke lol, post, then smoke
