Guys, I'm having the hardest time trying to clone my medicine and not sure what I'm doing wrong. I've tried both soil in cups and some gordon rockwool cubes I bought. They just eventually get yellow tips or curl under and die... no roots and I give them at least 10 to 14 days to start developing. I'm not sure if it's light, ph ..over watering or what. I poke holes in the plastic cups so the water can run off and the cubes are moist but not soaking wet. I've just bought a ph and ppm meter. The ph of my tap water is 8 and the ppm (tds) is 202, is this bad and do I need to buy RO filters or something? Also, I'm putting a little clonex on the cuts I take but from what I've read recently I'm suppose to be taking cuts that have a internode that can be below the medium. The room I'm trying to clone in is 72-80 depending on the time of day and I'm giving the clones 24 hrs light. I'm thinking the issues might be light or ph so I bought some GH ph down/up and plan on setting the tap water to 5.5. What kind of light has the best results? From my searches it seems T5's might work the best, lowes has some T8's at 17W a bulb but I'm not sure how many watts I need. It seems less is more when rooting but how much is less for say 1 to 2 squar feet? Walmart has a 17w linear fluorescent bulb with ballast for 10 bucks or lowes has a dual t8 setup with addon bulbs for $40. Also I'm seeing these LED shop bulbs, like fluorescent bulbs, at lowes in both dual and singular ballast for $40 bucks or so. One of my main questions about posting is ...does fluorescent or led root clones more efficiently? It seems like the fluoresent bulbs are what most people use but I don't mind spending a extra 10 dollars for led if they will produce the same or better and last a extra 3 years. And, then there comes into question the color rendering. Is there a particular color rendering that works better for clones? The local home depot and lowes have 4k but I can find 6500k online. I'm just trying to find the best way to clone at this point as I cant continue to buy the pricy seeds. Thanks in advance for any help!
