how do you break it up? i did not do that step, i just soaked/cleaned and planted. i have the grow cubes that are smaller than grow chucks. I am surprised that you do this since i thought there would be more air inbetween cubes and if you break it up, it would be more dense in the pot. Grow...

nice pics HR. I am finally adjusting to the rockwool loose fill. I didnt properly flush it before use so my ph was through the roof. Now that it is under control, that plants are taking off. One major difference i have noticed compared to sure-to-grow is the HUGE trunks that develop in rockwool...

i saw in another thread that you only flood about 2" up. Is that 2" up from the bottom of the inner bucket? Right now i have my buckets raised 1.5" above the floor so the inner bucket gets flooded 4" high. Should i raise them up even more since rockwool wicks so good. Seems like wicking would be...

do you have your buckets above the floor? i keep my on 2x4 for better drainage, so i am losing 1.5" of flood height. so far, the rockwool stays a lot heavier than the sure to grow. I am flooding every 12 hrs.

room temps are 80-82 during the day and 72-74 at night. Res temps are 64-65. rh is 45-53 (i have some plants in that room at week 7)

im leaning towards a calcium def, but i would like confirmation before i try to fix it so i do not create another problem. Ebb and grow with botanicare pure blend. This pics are from day 4 in flower after a 48 hr dark period. EC just under 1, but my mg:ca ratio is about 3:2 and i am using RO...

alright, got my 4x4x4 cubes transplanted into the ebb and grow with mini cubes. Everything look right? The cubes go about 2" above the flood level.

what do you guys do with the 4x4x4 rockwool blocks after they have lots of roots coming out of the bottom. I do not have ebb and grow buckets available for transplant yet and i do not want all the roots to get air-pruned.

thanks, that is what i figured, but could not remember reading it. I have been using stg deluge for awhile and have had good success, but it is difficult to preveg and veg for these. I recently started to preveg in the 6x6 hugos and the plants love it. I want to try out the loose fill next. Does...

what are you using since you not using tron?

here are a couple leave pics. -strain: bubblegum -ebb and grow -week 5 in flower -botanicare pure blend pro -1000w center of bulb is 16" above the canopy in a magnum hood These leaves were pulled from the colas right underneath the center of the bulb. The plants further from the bulb dont show...

When you transplant into hydroton, how far do you bury the rockwool? Is it below flood level? If it is above flood level, do you hand water until the roots grow down into the hydroton?

i agree with that kenny. The pex always looks heavier than its final weight. I used to get 4 oz off her

old dude, plants grow roots with extra P and they grow shoots with calmag. Check out this post, this guy has it down to a science. Even though its written for uc, it will still work for all mediums. https://www.thcfarmer.com/community/threads/how-to-properly-root-and-veg-in-the-uc.37827/

what grodan cubes are you using HR? You say 4x4, but what is the height? 2.5" or 4". Also, when you put these in the ebb and grow, how much of the rockwool cube is under the water-line?

thanks, i plan on wrapping the outside to block light. I will update in a week or 2 and let you know how it goes

here are some pics, there is 3" between the bottom of the net pot and the bottom of the top res.

i trying to setup a ebb and flow pre-veg system to transition rooted clones to ebb and grow. Right now i have the system built, but the plants are in net cups that are suspended in a bucket (similar to an aero system) and the roots are hanging underneath the pots. The plants are in rockwool in...

thanks for the info. So you use pondzyme instead of great white? Any there any other nutes/products your experimenting with?

wow, looks like im late to to party. ss, what application rate are you using with the pondzyme? how much and how often? glad to see everyone here...ss, old dude, and 907
