LED vs Cheap LED vs HPS Clones & Seeds

Update week 4 day 23. The girls are looking healthy, started them on cannaboost and massive bloom pk 50-33 on saturday, looks like there might be a couple of keepers 🤞🏼 Some nice phenotypes. I took some individual photos of some of the plants under the LED's. Complicated to take individual photos of every plant as there is 20 of them to get out the grow room.. Will be able to take some more when i do a clean out next week. So, what differences are there between the 205w Cob led ramps and the 600w viparspectra ? This is obviously a unfair test and would have to be done using clones only to make it fair ( mabey next time ) The 410w cob ramps are covering 1 square meter just like the 600w viparspectra ( more like 300w.. ) First is light penetration into the canopy, a lot more effecient in favor of the cobs, flower sites being more advanced on the bottom half of the plants. Second would be harvest weight, the plants seem to be putting on a lot more weight under the cobs. Third would be trichome production, now don't get me wrong, the viparspectra 600w is also very good at this test and is usually better then the HPS. From experience Leds have better trichome production and denser flower results then HPS. But the cobs are definetly on another level... Things are really getting sticky under there... 😎 So... Now i have kind of "beaten up" the viparspectra, why buy one ? The cobs are close to 400euros per ramp, thats 800euros... The viparspectra 600w is 169euros... I think the viparspectra is good for someone getting into leds and is good for growing 2 plants maximum in a 80x80 grow room using a Hst, Lst or Scrog technique to help with the penetration issus. In this case it's a great bang for your buck ! 👍🏼 I will obviously be doing some end results at harvest time. Thanks for following ! Hope you enjoy 😎
