Faster turnaround with smaller plants run 12/12 from the start, clones even faster. If growing larger plants I’d probably do no more than two. Coco is faster than soil and hydro if set up properly will beat even that. Figure two plants with primo lighting in that space will deliver 20 to 28 oz. of dried flower. Lighting is the most important component. Gotta have enough light.
One of my tents is a 3X3 I run two hlg 300lr specs in it usually run four plants sometimes three in 3 gallon pots with cocoa in a scrog net with a 6-week veg can consistently pull a pound and a half dried bud
First; I’m not a fan of DWC. RDWC with a decent sized reservoir is my preferred setup. A chiller is absolutely essential as is good instruments for monitoring PH and TDS along with primo lighting.
Having a rez means the PH and TDS remains stable much longer and does not need constant mixing and filling of buckets. That allows you to walk away from your plants for several days if you need to.
I’ve been using a bottom feed gravity system called ‘Autopots’ and have come to like them for their ease and growth. This doesn’t require air, wavemakers, chillers etc and the results are excellent. Plus you can walk away from plants for several days as well.
I would also advise being leery of lights sold on Amazon: if it’s cheap or it says “equivalent to X number of watts” they are being deceptive. Actual wattage needed varies depending on the quality of the light used. Top of the line LED’s smoke everything else on the market but you’re not gonna find them from overseas companies. HLG, Spyder Farm, CHILled tech, California Lightworks all use top-end diodes. Mars Hydro and lights like it do NOT despite their claims to the contrary. With high end lighting you can run 25 to 30 watts per square foot for good results. Cheap lights require 50 watts per.
That was a few months veg. Was a mother plant for clones. Requires good fimming or toping. Lst to spread to edges. Flip when tent covered. edge to edge.
I’m using the 3x3 Ionboard AC Infinity from California. I like the Spider Farmer as well, though the AC Infinity uses less electricity and burns cooler. Samsung diodes algorithmically positioned in all three colors. Nice. Not cheap. Spider Farmer might be better, but even with an additional AC and dehumidifier, a circulator fan and two in-line fans (one intake and one exhaust) it’s a chore to keep my Spider Farmer tent cool where I can walk away for a day or two. So far my first Jack Herer grow is doing well. I have followed the ILGM process to get to week 13, and am scrogging. I haven’t a clue what yield I will get. ILGM says 16oz to 18oz (per plant, I think) for JH per 3x3 which is why I ask 1 plant or more to increase yield. If one will do in a 3x3 and I get overall the same yield as growing three, why grow more than one? Maybe two. I sprang this first time for three, figuring that I might get a superior yield if I played my cards right. I’m on week 13 now and theoretically have one week to go. Online forum said I should have at least another two weeks on top of my calculations based upon my photos, but that otherwise everything looks bueno awesome. Waiting now for the pistols to change color and the trichomes to cloud.
Now that I am nearing the end of my first grow, I am asking for setups for my next round, which will likely be three indicas, this time different suits.
This go round I am using soil and have tried to keep it organic, though that is going to take some more time to cultivate in the future. Next go round I’m simply using coco with perlite (Mother Earth), recharge and a basic nutrient set.
Next time I should probably remove more of the lower growth before flower so as to maximize more of the main buds growth, and also try my hand at fimming to increase yield.
Best way to improve yield is experience and limit mistakes. If you are chasing yield, the strain grown is certainly important. Of course autos are out.
My experience is coco out performs soil.
Adding microbes improved output.
My best harvest (weight) was from Jack’s 321& coco. Previously used Advanced Nutrients Iguana and Fox Farm Trio. Both were in soil.
