Hey Dirt! I'll give you the sales pitch and no I don't get any commission, ha! the results speak for themselves, some really high quality produce is being grown in the kit! It's really easy to use, almost fool proof! No need to check ph of water or soil, the kit keeps the soil at optimum ph, that was one of the things that sold me, I hated using ph up/down! No flushing! The kit is one of the least expensive systems on the market. You buy the kit, a bale of Pro mix hp, 30lbs of EWC and mix together with amendment from the kit, let "cook" for 30 days in temp range of 65-80 then it's good to go! After the first grow is done you re amend and let sit 30 days before use, most do 3 runs but some do more. The kit will provide about 42 gallons of soil, directions for 1 run are to do 6 plants in #7's but I've done 4 #10's, 3 #15's and now have 2 kits running at anytime so I don't have to wait 30 days. I recommend the bulk kit as you save a little and it will last longer, with the regular kit, you may need to reorder sooner, I.e. We are now using the drenches (basically the food, transplant, growth and catonic) heavier than originally with great results. Also, there is lots of great support! An awesome crew, a sub group of the already awesome 420 mag. You can do all that awesome training as usual. Some say using the kit can get boring because they really run on cruise control! That's my pitch! I've been using it for about 3 years and will never use another system! Let me know if you have any questions.
