I thought seriously about going with LED's just because of the constant battle I have with heat issues, but instead, I decided to go with a 400w vs a 600w or 1000w light.. Although I'd love to add some LED strips for side lighting eh !!
Man, I've been thru all the soils: Foxfarm's both light warrior and Ocean Forrest, 3 types of Pro mix be it the compressed 3.8 cu ft units or the bags, Coirbrick in small bricks to 5kg large bricks but found out if you purchase the wrong type you'll battle nutrient issues or retaining sodium.. Used Coco for a few years and finally got tired of fighting headaches with it.. then took a break for almost 5yrs until about 9mos ago.. got lucky and purchased an entire Roots Organic starter kit w/light, foods etc etc for $299 at Xmas time and never looked back.
This soil is the best I've ever used and re-used now 3x's

Make sure you use this exact green bag and stay away from the one called " 707 " as the soil in that one is a bit more for outside work ok... Now I used to do this years ago using a friend, Subcool's , own private mix he created.. Problem is it cost me a buttload of $$ to make it and it was much more then I needed, breaking down the ingredients for a smaller grow was not easy either...
Plus, when I found this stuff by Roots it has most of the products he used and I found that very cool.. the great thing about this is for Auto Flowering it has almost everything a plant needs and matter of fact my 2nd grow I fed them once during veg and once during flowering using only a PK booster.. best hidden secret of an experienced grower man... PK 13/14 used at week 5-7 depending on finishing time.. you won't regret switching to this.... nice price too...
