Hydro grows don't use potting soil. They are soiless grows. You just use something to hold the plant, like hydroton, rockwool, rapid rooter. When growing in potting soil let the soil dry out some before you water again. Certainly don't water every day. You might not have to fertilize at all for the first week or so. You might want to ask the maker of the soil if there is fertilizer already in the soil and about how long it will be good for before you have to fertilize.
polishpollack Reviewed by polishpollack on . Hydro question on feeding Have used FF soil in the past. Going to use Sunshine mix #4. I will be in veg and flower in 3 gallon pots. Growing 6 Liberty Haze under 1000w. I am totally unfamiar with where to go from there. I know that I should first use Calmag in the RO water. I will be using Foxfarms grow big for veg and big bloom for flower along with Tiger bloom. What kind of feeding schedule should I have? When using a soil less mix I would assume I need to fertilize every day when I water them. What would that look Rating: 5
