A lot of closed minded ignorant assholes in this thread that have apparently never heard the term "light recipe"... too bad "Researchers in the Netherlands are experimenting with “inter-lighting” to improve yields, especially in taller crops. HID lamps are still the primary overhead light...

University studies show that blue light and subtle red lights under the canopy during flower increase cannabis dry bud mass by 19.8% and pushes THC creation up by 4.0% and full spectrum colors under the canopy increased yields by 24.5% according to their empirical data. Tents/heat/and other...

I don't like or trust LED grow lights with a hundred little LEDs in them; about a hundred things that can go wrong IMO and I think its just a dumb design overall (especially the ones with computer fans in them). I like COB LEDs where I can have my array and if a COB or power supply goes bad, I...

There should be a "Hempy book" released put out by a pro Hempy grower that wants to make a million dollars... Flood and Drain, dirt/organic and DWC methods all have relative feeding regimens from seedling to end of flower explained in fine print on the back of the bottle, Hempy does not. This is...

Yes, I'm feeding around 0.5 - 0.6 EC once I place the 3 - 4 node seedlings in 4x4 rock wool cubes into the buckets for the first time waiting for roots to hit the Rez top feeding multiple times per day small amounts. One more question sorry, you said - " i add Mg to mine, no Ca." during veg" -...

I'm going to take your advice and get no where near 700+ ppm and watch the plants closely feeding regularly.. What I'm most sketched out about is placing 2 - 3 node two week old seedlings I have in 4 x 4" rock wool cubes into the 100% perlite Hempy Buckets and as those roots hit the Rez for the...

I'm switching from FND 4 x 8 tables using rock wool to all perlite Hempy buckets for the first time. Is there a ballpark ppm EC to shoot for in Hempy over time to not burn the Hell out of them? Like: Seedlings 150 - 200 ppm rising 50ppm each week until first week of 5 - 6 node veg around 400...

All Perlite, 4 gallon buckets they are in their first week of actual veg (5 - 6 nodes) and I'm feeding 400 ppm (0.8 EC) of nothing but GROW. PH 5.8 every time. Feeding every 2 - 3 days atm.

I'm switching from HPS to COBs... Dyna says - "Liquid GROW™, Foliage-Pro® and Liquid BLOOM™ are complete nutrients containing all 16 macro and micro nutrients your plants need to thrive. ... You do not need a Cal-Mag supplement when using Dyna-Gro™ nutrients." Is this true for cannabis under...

I have no AC dude... I just vent tent air from my 6 x 6 and 4 x 4 indoors to outdoors with my house AC doing all the work... these are like accordions and can fit every house window out there..

Dude... do you realize how much fiberglass from that insulation is going to be all over your smoke? That could give you lung cancer with the quickness.
