no big investment needed
i have a ecoplus 396 pump $20
walmart aquarium pump $10
raindrip 1/2" tube 50ft $11.95
drip lines and stakes $1.50 each ( i use 2 per site)
bucket and bucket netpots $8.50 per site
keep your ph at 5.2-6.2 ppms no higher than 1400, no worries
or you could do dwc for about $26 i did this but you use alot of nutes
i run a combo of a top fed drip/ dwc in 5 gallon buckets, that gives me complete control of eaht they are given, the only downfall is since im perpetual the 2 week flush i give is enough for taste, but usually not colors. which since its a personal only grow, bag appeal (colors) dont matter to me
well I don't have a refered pic anymore...my avatar used to represent my problem quite well, but I have been told that it is natural for the leaves to get yellow and get shitty looking (especially in indoor soil grows) but basically what your saying is that you have a closely watched hydro setup that gives optimal attention to the needs of the plants? i would love to switch to hydro...nervous about fucking up the big investment though.
