Love the light Jela, the girls look happy too...I did not know it had different modes.
Thanks, Jela, for the informative thread. I'm just in the process of setting up my first Hempy grow and I have a few questions. First off (first off, how do make paragraphs in these thread boxes?), do you use any perlite at all? Looking at your two gallon buckets, it appears it's straight coco. The guy at my local hydro store said to put some perlite in the coco -- for air circulation, I presume -- so in the starter cups for my clones I mixed a 3:1 ratio of coco to perlite. Second, I'm wondering if there's a difference in the growth of the plants when using the rockwool mini-cubes in the reservoir as opposed to perlite. You mentioned that with perlite in the reservoir, the roots grind to a halt and don't penetrate that layer. Does this stunt the growth of the plant? Conversely, do the plants have better growth when they grow into the rockwool cubes deep into the reservoir? One other question, your new lighting system aside, it sounds like I have a similar set-up to you: a 400watt HPS for flowering in a 3.5' x 4' cabinet with about a 6' ceiling. So I've been growing a maximum of eight small plants -- in what appear to be 3 gallon buckets -- in Promix-perlite. (A dusty combination, especially when you're mixing inside during the winter, so I like the idea of ditching the perlite for mini Rockwool cubes). In your opinion, is eight buckets in that space too many?I've grown fond of Grodan's mini-rockwool cubes and have been playing with them as additions to the coco. Where they seem to be working best is in the hempy reservoir. There is a strange phenomenon I and others have noticed with growing in coco. If there is a layer of perlite in the bottom of the hempy bucket, the roots stop at the bottom of the coco and will not pervade the 2" perlite zone. That's funny since the original hempy bucket was all perlite and roots went right down into the reservoir.
Highocaine, glad to have you over hempy brother. I use R/O water which is a consistent 5.8. I add the alkaline ingredients first to buffer the solution (Cal/mag, Rhizotonic) which takes it up to 6.0-6.2. Then I add the acidic base nutes and additives that takes me back down to 5.6 -5.8. Since my R/O water is always the same, I don't ever check it anymore. I don't even look at PPM anymore unless I'm precharging a medium like Mapito. I run back & forth between Canna Coco A&B and Canna Substra Vega/flores A&B depending on the non-coco percentage of the medium. Canna Substra has a hard & soft water version and I use the "soft" version for R/O water. Some will tell you the hempy bucket is less sensitive to pH and I really can't agree/disagree. I just keep consistency in my feedings and follow the strain's needs if it's a weird one.Why am I not subbed already, argh. Sorry I'm late, they look great! Keep it up!
Might be a silly question, but do you PH your nutes at all, or just follow the Canna schedule? My pen ran dead a couple weeks ago.. haven't bothered to replace the batteries.. growth looks fine though.
