I've got about 5 feet for height. I actually am not going with the Hazes, I began soaking my AK47 seeds today. A friend of mine has almost 100 AK's going right now so I can use his progress as a reference to mine. I like to start seeds in rockwool as I have done before, and the beauty of using ebb and flow is you can put the seeds in your rockwool, and then directly into the ebb and flow system with the correct depth to keep the rockwool properly moist. I use a heating pad at this stage under the resevoir to keep the temp up a bit to enhance germination. Nutes are 1/3 strength, ph is a hair lower than veg/flower cycle. Take a looksee.............
