did already, on 3/19. and so that means, to be precise, that the girls started week 4 of bloom this past monday, and are technically at 4.5 weeks of bloom now.
the FSS EFDL lamps were the first lights i got for my grow, they were donated to me. all the plants in bloom now were started under those EFDL lamps and were only exposed to that light for the 4-5 weeks of veg. when i switched to bloom, i pulled the 200w FSS out of the tent and replaced it with a 600w HPS that was also donated, but that i was curious about comparing as much as i could against the 400w EFDL. at 3.5 weeks into bloom, the FSS 400w crapped out. it had been over the PDP and my grand daddy purp. i replaced it with the 200w, which due to being smaller, had to sit over the PDP alone, and the GDP got shuffled into the HPS area. i ordered the 2 Inda-Gro lamps on the 12th, the day after the failure of the FSS 400, and they got to me on the 17th. i pulled the 200w out and put the 420PAR in over the PDP, lifted it a bit, and moved the GDP back under it. i also moved the White Fire into the middle area, hoping that the fuller spectrum side light will help to stop some of that crazy etoliation. i figure that by the 24th, the differences will be apparent, and pictures will leave little doubt.
i also have some clones set up for a more precise test. i really don't like that i have 5 different strains that i am trying to gauge light differences off of, so i have a matched pair (literally identical size and node pattern, taken from matched tops) of WF clones and PDP clones set up in veg now (under the two 200w EFDLs). i will be doing them up in identical pots and soil all the way thru. straight Happy Frog soil, Ricks Monster Grow, Great White, Bio Canna full line + Rhizotonic, Hygrozyme, Canna Boost, Canna PK13/14, Tarantula, all in distilled water. their mommies went up to 16ml/gal on Bio Vega as well as Bio Flores, so i know what to expect in the next run. but also, the WF is the tallest one in the tent now, and the PDP is the shortest; i'll have the data to show how much the lights cause etoliation on a strain that seem to be prone to it and one that seems not to be. o, also... the plants under the HPS seem to be fond of the powdery mildew. i have been staying on top of it with Serenade, but in doing so i have noticed that to date, the PDP has not needed to be sprayed once. she has never shown a speck of PM. at first i thought that it was just her genetics being all bad ass and resistant to PM, but then i recalled that i never saw a trace of PM in veg, and the tent was running at 85F/70RH. only thing was that it was all EFDL light. now, it's only the ones under the HPS that have bits of PM showing. i re-treated them with Serenade and moved the GDP back out from under the HPS, and i'll keep an eye on her potentially picking up PM again under the 420PAR. at this point i'm beginning to suspect that it might be something more related to the light. if the GDP pulls PM again, i'll have to tend to think that the lack of PM on the PDP means that she really is just that bad ass, and i will have a hard time wanting to grow anything else from there on out.
also, please no powder mildew thread hijackers... i have a filter solution ready to employ, but i need to move the tent into a larger room first and want to just finish this crop. then i'll break down, clean and relocate with filtered air charging the tent. i figure that with the details that i'm noticing now, i might as well also allow me the time to split the hair a little. it would be really nice to know one way or another if these light spectrums have any impact on PM.
