hugos are the 6x6 rockwoll cubes, at least so i thought. I am deffinately gonna do ebb and flow next round. Probably 24 per 4x8 tray, veg for 14-18 days depending on how fast they take off. I always do this, i have a good run then get so excited to try new things that i think will help, but it always sets me back, i need to just stick to what i know and just try to get to know the strains better in order to increaase yields, not the setup. The best ive done so far is get 3 # off a 4x8 which is not very good, at least with the company on here. But what ive learned is most of these growers have been doing this for years, this is my 3rd year, with a big move also, so i have been constantly trying to get things dialed in. When i started i had one 1000watt light and have slowly built up to 6, but i didnt know about forums or sites like this till last year. Thats when things went down hill, i started to try all these new ways that i was seeing on the internet, and needless to say, my productionb went down. However i am finally content with my style and will be returning next round!
