    using 6" pots ffor SoG style on 2x3 foot Ebb & Flow table with 400watt HPS/MH setup. Was thinking of growing clones/cuttings in 3x3" rook wool under flouresence, then into 6" pot with Promix (rock wool cube in center) and using MH then HPS. Flowering at about 8-10" on 12/12.....also tips on good beginner nutes would be great :P...PICS to COME

    If you are going ebb & flow I would use Hydroton for grow medium and how many plants all depends on what kind you are growing.

    just checking in. i use 4 in rockwool cubes in 5.25 in turbogarden pots with mini cunes making up the diference. 3 girls outa 12. only 1 is healthy as the 2 got pre nute damage and never made a full recovery.

    the healthy girl is loving it. HUGE! at least i think. the other 2 are, well, lets put it this way, i now know to watch the early nute and also when in the big rockwool blocks watch the over water. it wont kill it but it willDRAMATIcally slow the growth.

    i did a compariosn and even a day as I backed off watering growth exploded. let the plants get light weight then feed. in all rockwool i did every few days during veg then every day in flower.:)

    there are many different things to use but the most popular is hydroton balls. I use to run a 75/25 mix of hydroton and rockwool cubes in my 4x4 trays but since the seasons changed i had issues with the rockwool geting moldy and now im just using straight hhydroton. It works ok but it doesnt hold nearly the mostoiure as the rockwool did before.

    you can put your rockwool straight into your ebb and flow tray filled with hydroton. i would fill the whole tray with about an inch and half of hydroton and stick your rock wool right into it. this allows your roots to go where they want to

    should i put the rock wool in the planter pots or just rate into the reservoir fill with hydroton, i think im gunna use pots cause it protects rock wool cubes from evaporation from light. Also im growing an indica strand, short flowering time and average yeild

    I don't use pots with Ebb & Flow but I don't see why you couldn't. Jjust put some Hydroton in first then rock wool cube and the another inch of Hydroton on top. You might be able to get 15-20 in there. Good luck and keep us posted on your progress.

    you want the water in the rockwool to evaporate, having soggy,wet rockwool the entire time will only lead to problems (root rot, disease). you can put them in pots, but in my opinion pots are a limiting factor, and i try to eliminate limiting factors.

    If only using rockwool, no pot whats a good size rock wool cube to do SoG style out of, which size will hold the plant the best whne its 1' high, i have seen other ebb and flows were they place the entire rock wool sheet in the table, but wasent sure on the good size rock woll for entire growth cycle. I realize SoG is only growing the plant to have one cola, but it rockwool strong eoungh to hold the maturing plant.....if i keep the rock wool in the slabs and not break them apart will it be more structural to hold all the plants?...i have seen 6x6x6" rockwool in slabs of 30 i think, if i broke off 10 rock wool cubs and placed the slab containing 20 into the table....would this work well?....mabey cover with thin layer of hydroton? thanks your guys help is awsome......pics to come waiting for table in mail:P

    yeah 6x6 rockwool. but with a thin later of hydroton the rockwool wouldnt really have to support the plant because the roots will grow into the hydroton giving it a good foundation.
