Hello all. We are 4 weeks away from our second run harvest with the Alien system. 3x Northern Lights and 1x of a strain called LA grown from clones. We haven't experienced any pipe blowouts or leaks this round thank goodness. The system overall is definitely the right investment. It's producing ridiculous buds in quantity and in density. We've never had a dead leaf, they are the healthiest plants you'd see. It does make it hard to keep humidity down, so we've invested in a high end dehumidifier which has eliminated that concern. We use Athena blended fertilizers. Adding cleanse in a bit more than the first round appears to have helped clean the scale from within the pipes. We also turned down the water a degree and 65⁰ is the set, but the chiller and heater keep it between 65-67⁰. We noticed very light root rot at the tips which we didn't know about until we harvested and pulled the root balls up so we're hoping the added cleanse and lower temp will prevent that in this run.
We just started germinating our next run from seeds, and after a week of cold stratification we had gone from seed to 2 inch seedlings in 26hrs, unbelievable! We're going with Jack Herer seeds from a bank that's got a proven yield of 1+lb dried per plant indoors.
