hi NG. congrats on this thread bro, i think this is awesome. i read over half of it and it solved many of my questions. i still want to ask u something. im planning on running 2x600w hps, and im planning to make my own hidro sistem. so here goes the avalance of questions
1. im planning on using adjustawings medium with my lights. the site sais i could cover 1.25x 1.75 meters. thats about 2 square meters per light kit. Do u think the bucket sistem works good with this light coverage, or maybe i should make a pvc pipe sistem that would sustain more and smaller plants, rather than few large plants ? both sistems are drip based sistems
2. on both sistems (pvc pipe and buckets) there will be a small ammount of water so the roots can stand in it. would that level of water be the same componence as the main nutrient solution in the tank ? i'm thinking maybe the nutrient level may increase as the water evaporates. my main concern is that when the roots stay in that bottom solution they wont get damaged or something.
3. regarding the bucket sistem, does the size of the top bucket filled with expanded clay pellets make any difference ? i.m planning on vegging for 4-6 weeks. i mean can i grow the same plant and same yield with both 10liter top bucket as with a 20 liter ?
4. do clay pebbles retain water, because i dont know how the plants will get thru a power shortage(may happen, but not often).
5. regarding the bottom water level the roots stay in, should i run air lines to oxigenate that water, or will 2-3 airstones in the tank be sufficient ?
6. also could u aproximate the power the pump needs to have for this sistems(buckets & PVC) ?
also if u have any sugestion on what should i choose or add in this hidro design would be greately apreciated. also the room im setting this up is at least 10 square meters, so im gonna put mylar on 2 walls that should take care of one side of the grow space, and for the other 2 sides i will be setting up easy to move mylar walls (cardboard with mylar on a vertical structure to act as walls for grow area) also how powerfull should a pump be to work for 13-15 bucket or the pvc pipe design. also is it posible to overwater in dripper sistems ? i dont think its possible but still worth a question. sorry about being unorganised at the end of message but the haze is starting to kick in lol. also i would like to thank you in behalf of the forum for helping inexperienced growers. peace bro.
LATER EDIT: what mediium should i use to start seeds or clones in this kind of sistem ? im asking because i dont know if i should drip around the rockwool or on it ? also if i drip around the rockwool cube, the roots in the rockwool wont become dry, causing problems for the plant ? sorry for bad spelling and bad english and poor exprimation skills, but english is not my native language. peace bro and tx again for helping the forum out.
