First time growing in coco coir and perlite. It\'s quite different that hydro, aero-ponics, soil and anything else I grew in. It holds the water and nute in for a long time. Sometimes I go for 3 and even 4 days without watering. I lost my first crop of Haze Extreme for not paying attention. I seen the bottom leaves turn upwards so I thought it was nitrogen defeciency, I added some nitrogen to a little water and added it to all 10 Haze Extreme plants. Mostly all wilted within 5 minutes upon adding the extra water with nutes. I called my neighborly grower and asked him to see what was going on. Needless to say, I was way over watering them (everyday in fact). We took out the plants from the pots pulled the potting mix away from the fragile roots and re-planted them in dry coco coir and perlite mix. 4 out of 10 Haze Extreme pulled through with a little shock, but they\'ll grow along with the 2nd crop I planted 4 weeks after the first. Took the absorbsion into consideration for the Purple Kush and water lightly every 3-4 days. They all blow-up fast!! In 2 more weeks I\'ll be cloning of the 10 Purple Kush babies, and finally have my quot;sea of greenquot; I\'ve always wanted. Then 4 weeks later, here comes the Haze Extreme clones. Whoa!!
